Opinion
BAXTER, J.
California has, in various statutes, limited the circumstances in which a peace officer may effect a custodial arrest for minor offenses. (E.g., Pen. Code, §§ 818, 827.1, 853.5, 853.6; Pub. Resources Code, § 5786.17; Veh. Code, §§ 40302, 40302.5, 40303, 40303.5, 40304, 40305, 40305.5.) California also has, by the passage of Proposition 8 in 1982, limited the circumstances in which a trial court may exclude relevant evidence as a sanction for the violation of these state statutes. (Cal. Const., art. I, § 28, subd. (d).) As we have previously observed, state statutes limiting police discretion are not inconsistent with the state constitutional provision limiting the exclusion of evidence as a sanction for their violation. The “substantive scope” of state statutes governing the ability of peace officers to effect a custodial arrest for minor offenses “remains unaffected by Proposition 8.” (In re Lance W. (1985) 37 Cal.3d 873, 886 [210 Cal.Rptr. 631, 694 P.2d 744].) “What Proposition 8 does is to eliminate a judicially created remedy for violations of the search and seizure provisions of the federal or state Constitutions, through the exclusion of evidence so obtained, except to the extent that exclusion remains federally compelled.” (Id. at pp. 886-887.)
In this case, the only remedy defendant Conrad Richard McKay seeks is the exclusion of a baggie of methamphetamine that was found in his sock during a search incident to his arrest for the infraction of riding his bicycle in the wrong direction on a residential street. Defendant argues that a custodial arrest for a fine-only offense, such as a traffic infraction, violates the Fourth Amendment prohibition on unreasonable seizures. He also argues, in the event the Fourth Amendment does not bar such arrests categorically, that his custodial arrest nonetheless violated the federal Constitution by the deputy’s failure to comply with Vehicle Code section 40302, subdivision (a) (section 40302(a)), the state statute that governs the arrest procedure for this infraction.
We conclude, in accordance with United States Supreme Court precedent, that custodial arrests for fine-only offenses do not violate the Fourth Amendment and that compliance with state arrest procedures is not a component of the federal constitutional inquiry. We also conclude, in the alternative, that the arrest here complied with section 40302(a). Accordingly, we affirm the judgment of the Court of Appeal.
[606]*606I
Background
Around 6:00 p.m. on June 19, 1999, Los Angeles County Deputy Sheriff Valento observed defendant riding a bicycle in the wrong direction on a residential street. Deputy Valento initiated a traffic stop, intending to issue defendant a citation for violating Vehicle Code section 21650.1.1 The deputy asked defendant for identification. Defendant said he did not have any identification with him and instead told the deputy his name and date of birth. Deputy Valento took defendant into custody, pursuant to section 40302(a), based on his failure “to present his driver’s license or other satisfactory evidence of his identity for examination.” During a search incident to that arrest, Deputy Valento found, in defendant’s left sock, a baggie containing an off-white substance he believed to be methamphetamine.
After placing defendant in the back of the patrol car, Deputy Valento entered the name and date of birth defendant had provided into the patrol car’s computer and received an address that matched the address defendant had given him and a general description that was consistent with defendant’s appearance.
Defendant was charged with possession of methamphetamine (Health & Saf. Code, § 11377, subd. (a)) and alleged to have suffered a prior strike conviction. He moved to suppress the evidence, pointing out that he had given his name and date of birth to Deputy Valento, who was subsequently able to “check it out through the computer.” After the trial court denied the motion to suppress, relying on People v. Monroe (1993) 12 Cal.App.4th 1174 [16 Cal.Rptr.2d 267] (Monroe), defendant pleaded guilty, admitted the prior, and was sentenced to the doubled term of 32 months. A divided panel of the Court of Appeal, once again relying on Monroe, affirmed his conviction.
II
Defendant was arrested for violating section 21650.1, which requires a bicycle to be operated “in the same direction as vehicles are required to be driven upon the roadway.” This infraction is punishable by a fine not to exceed $100. (§§40000.1, 42001, subd. (a)(1).) There is no dispute that Deputy Valento was justified in stopping defendant based on this violation. Rather, defendant argues that a custodial arrest for such a minor offense violated the Fourth Amendment. If such arrests are valid, he then argues that [607]*607once he provided his name and date of birth, the deputy lacked authority to effect a custodial arrest under section 40302(a) and that this asserted violation of state law thereby violated the federal Constitution.
A
Appellant’s first contention, he now concedes, is foreclosed by Atwater v. Lago Vista (2001) 532 U.S. 318 [121 S.Ct. 1536, 149 L.Ed.2d 549] (Atwater), which upheld a custodial arrest for a violation of Texas’s seatbelt law, an offense punishable by a fine of not less than $25 nor more than $50. (Id. at p. 323 [121 S.Ct. at p. 1541].) Under Atwater, all that is needed to justify a custodial arrest is a showing of probable cause. “If an officer has probable cause to believe that an individual has committed even a very minor criminal offense in his presence, he may, without violating the Fourth Amendment, arrest the offender.” (Id. at p. 354 [121 S.Ct. at p. 1557].) We must therefore conclude that there is nothing inherently unconstitutional about effecting a custodial arrest for a fine-only offense. (U.S. v. McFadden (2d Cir. 2001) 238 F.3d 198, 204 [upholding search incident to arrest for riding a bicycle on the sidewalk].)
B
Although Atwater permits the police to effect custodial arrests for even the most minor of offenses, many states—including California—have sought to limit this broad discretion by statute, local ordinance, or departmental regulation. Defendant relies in particular on section 40302(a), which requires the officer to effect a custodial arrest for nonfelony Vehicle Code offenses when the offender fails to present a driver’s license “or other satisfactory evidence of . . . identity for examination.” Defendant claims that his oral statements to the deputy constituted “satisfactory evidence of . . . identity” under section 40302(a), rendering his arrest unauthorized under California law. The Attorney General, on the other hand, contends that the deputy complied with California law in that section 40302(a) requires an officer to accept only a driver’s license or its functional equivalent.
Before we resolve the dispute over the construction of section 40302(a), though, we must first determine whether compliance with state arrest procedures affects the validity of an arrest under the federal Constitution. Neither the majority nor the dissent below considered this threshold issue, nor did the majority and dissent in Monroe. The issue, however, cannot be ignored. [608]*608With the passage of Proposition 8, we are not free to exclude evidence merely because it was obtained in violation of some state statute or state constitutional provision. “ ‘Our state Constitution . . . forbids the courts to order the exclusion of evidence at trial as a remedy for an unreasonable search and seizure unless that remedy is required by the federal Constitution as interpreted by the United States Supreme Court.’ ” (People v. Camacho (2000) 23 CalAth 824, 830 [98 Cal.Rptr.2d 232, 3 P.3d 878], quoting In re Tyrell J. (1994) 8 Cal.4th 68, 76 [32 Cal.Rptr.2d 33, 876 P.2d 519].)2
Thus, in order to prevail, defendant must show as an initial matter that a Los Angeles County deputy sheriff’s compliance with state procedure is pivotal to the validity of an arrest under the federal Constitution. We requested supplemental briefing to determine whether defendant’s arrest, notwithstanding its constitutionality under Atwater, became unconstitutional because it assertedly was not authorized by section 40302(a).3
[609]*609This is a rickety foundation on which to base a federal constitutional argument. It is a well-settled part of “ ‘Our Federalism’ ” that “the National Government will fare best if the States and their institutions are left free to perform their separate functions in their separate ways.” (Younger v. Harris (1971) 401 U.S. 37, 44 [91 S.Ct. 746, 750, 27 L.Ed.2d 669].) “[A]nxious though it may be to vindicate and protect federal rights and federal interests,” the federal government “always endeavors to do so in ways that will not unduly interfere with the legitimate activities of the States.” (Ibid.) For this reason, the United States Supreme Court has repeatedly resisted efforts to invoke the federal Constitution to force state officials to comply with state law. (See Woolhandler, The Common Law Origins of Constitutionally Compelled Remedies (1997) 107 Yale L.J. 77, 161 [“Such a decision seems inevitable if there is any continuing wish to maintain a federal system”].) Rather, where state officials have been derelict under state law, the high court has reminded us that the illegality of such conduct “under the state statute can neither add to nor subtract from its constitutional validity. Mere violation of a state statute does not infringe the federal Constitution. [Citation.] And state action, even though illegal under state law, can be no more and no less constitutional under the Fourteenth Amendment than if it were sanctioned by the state legislature.” (Snowden v. Hughes (1944) 321 U.S. 1, 11 [64 S.Ct. 397, 402, 88 L.Ed. 497].)
To assert (as defendant does) that state law can transform constitutional police conduct into its opposite would unravel our federal system, since treating a state law violation as a violation of the Constitution “is to [610]*610make the federal government the enforcer of state law.” (Archie v. City of Racine (7th Cir. 1988) 847 F.2d 1211, 1217 (in bank).) This, of course, is precisely what the federal Constitution forbids. “A federal court’s grant of relief against state officials on the basis of state law, whether prospective or retroactive, does not vindicate the supreme authority of federal law. On the contrary, it is difficult to think of a greater intrusion on state sovereignty than when a federal court instructs state officials on how to conform their conduct to state law.” (Pennhurst State School & Hosp. v. Halderman (1984) 465 U.S. 89, 106 [104 S.Ct. 900, 910, 79 L.Ed.2d 67] (Pennhurst).) “If the alchemist’s wand can transmute a violation of state law into a violation of the Constitution, Pennhurst will be for naught, federal enforcement of state law the order of the day.” (Archie v. City of Racine, supra, 847 F.2d at p. 1217.)
It will come as no surprise, then, that the United States Supreme Court has never ordered a state court to suppress evidence that has been gathered in a manner consistent with the federal Constitution but in violation of some state law or local ordinance.4 To the contrary, the high court has repeatedly emphasized that the Fourth Amendment inquiry does not depend on whether the challenged police conduct was authorized by state law.
In Cooper v. California (1967) 386 U.S. 58 [87 S.Ct. 788, 17 L.Ed.2d 730] (Cooper), for example, the defendant complained that the search of his vehicle was not authorized by California’s forfeiture statute and was thus unconstitutional. The court found instead that the state law inquiry and the constitutional inquiry were distinct: “the question here is not whether the search was authorized by state law. The question is rather whether the search was reasonable under the Fourth Amendment.” (Id. at p. 61 [87 S.Ct. at p. 790]; see also Sibron, supra, 392 U.S. at p. 61 [88 S.Ct. at p. 1902].) More recently, the court has observed that although individual states may construe their own laws as imposing more stringent constraints on police conduct than does the federal Constitution, “[w]e have never intimated . . . that whether or not a search is reasonable within the meaning of the Fourth Amendment depends on the law of the particular State in which the search occurs.” (Greenwood, supra, 486 U.S. at p. 43 [108 S.Ct. at p. 1630].) “In determining whether there has been an unreasonable search and seizure by state officers, a federal court must make an independent inquiry, whether or not there has been such an inquiry by a state court, and irrespective of how any such inquiry may have turned out. The test is one of federal law, neither [611]*611enlarged by what one state court may have countenanced, nor diminished by what another may have colorably suppressed.” (Elkins v. United States (1960) 364 U.S. 206, 223-224 [80 S.Ct. 1437, 1447, 4 L.Ed.2d 1669] (Elkins).)
Our determination of the validity of the search under the federal Constitution thus does not depend on whether “it was authorized by state law” (Cooper, supra, 386 U.S. at p. 61 [87 S.Ct. at p. 790]) or “the law of the particular State in which the search occurs” (Greenwood, supra, 486 U.S. at p. 43 [108 S.Ct. at p. 1630]). According to Elkins, supra, 364 U.S. at page 224 [80 S.Ct. at page 1447], the test “is one of federal law”—and, in this case, was disposed of by Atwater. Therefore, we need not consider whether defendant’s arrest complied with section 40302(a).
Defendant, however, argues that a different line of Supreme Court authority makes state procedure relevant to the constitutional calculus. He begins with United States v. Di Re (1948) 332 U.S. 581 [68 S.Ct. 222, 92 L.Ed. 210] (Di Re). Di Re was convicted in federal court of knowingly possessing counterfeit gasoline coupons, which were found on his person following his arrest “by a state officer accompanied by federal officers who had no power of arrest.” (Id. at p. 591 [68 S.Ct. at p. 227].) The government sought to justify the search as incident to the arrest. The court stated that because “[n]o act of Congress lays down a general federal rule for arrest without warrant for federal offenses” (ibid.), the rule would be that “the law of the state where an arrest without warrant takes place determines its validity.” (Id. at p. 589 [68 S.Ct. at p. 226].) The law of New York, where the arrest occurred, permitted an arrest where “ ‘a felony has in fact been committed’ ” and the officer “ ‘has reasonable cause for believing the person to be arrested to have committed it.’ ” (Id. at p. 589, fn. 7 [68 S.Ct. at p. 226].) Finding no probable cause to effect the arrest, the court affirmed the order suppressing the evidence seized during the search incident. (Id. at pp. 593-595 [68 S.Ct. at pp. 228-229].)
Drawing on Di Re’s adoption of state law as a general federal rule of arrest, defendant submits that Di Re compels us to measure the constitutionality of this warrantless arrest under California law in general and under section 40302(a) in particular. If Di Re had grounded its adoption of state law on the federal Constitution, defendant’s submission would be sound. Unfortunately for defendant, the court did not do so.
A review of Di Re reveals that its adoption of state arrest procedure was a matter of statutory construction, not constitutional compulsion. The court [612]*612derived its rule for arrests without a warrant from congressional enactments for arrests with a warrant. “By one of the earliest acts of Congress, the principle of which is still retained, the arrest by judicial process for a federal offense must be ‘agreeably to the usual mode of process against offenders in such State.’ There is no reason to believe that state law is not an equally appropriate standard by which to test arrest without warrant, except in those cases where Congress has enacted a federal rule. Indeed the enactment of a federal rule in some specific cases seems to imply the absence of any general federal law of arrest.” (Di Re, supra, 332 U.S. at pp. 589-590 [68 S.Ct. at p. 226].) The court thus was faced with an issue squarely within its supervisory power: the choice of law by which to measure the validity of arrests in federal prosecutions. Nowhere in its discussion did the court rely on or even mention the federal Constitution. Rather, the high court, in a federal prosecution, exercised its supervisory role over the federal courts—as the lower federal courts and other state courts have concluded. (E.g., U.S. v. Wright (6th Cir. 1994) 16 F.3d 1429, 1435 (Wright); Fields v. City of South Houston, Texas (5th Cir. 1991) 922 F.2d 1183, 1189-1190, fn. 7; Street v. Surdyka (4th Cir. 1974) 492 F.2d 368, 372, fn. 7; People v. Dyla (1988) 142 A.D.2d 423, 434-435 [536 N.Y.S.2d 799, 806].) Commentators, too, have noted Di Re's nonconstitutional foundation. (E.g., 1 LaFave, Search and Seizure, supra, § 1.5(b), p. 138 [“a close inspection of the Di Re decision indicates that the use of state law there was ‘based on nonconstitutional considerations’ ”]; 2 Ringel, Searches and Seizures, Arrests and Confessions (2d ed. 1979) § 23.9, p. 23-71 [“Suppression of evidence resulting from the illegal, but not unconstitutional, arrest is not mandated”].) Accordingly, the high court has cited this aspect of Di Re only in other federal prosecutions. (See United States v. Watson (1976) 423 U.S. 411, 420-421, fn. 8 [96 S.Ct. 820, 826-827, 46 L.Ed.2d 598]; Miller v. United States (1958) 357 U.S. 301, 305-306 [78 S.Ct. 1190, 1193-1194, 2 L.Ed.2d 1332]; Johnson v. United States (1948) 333 U.S. 10, 15 & fn. 5 [68 S.Ct. 367, 370, 92 L.Ed. 436].)5
Without Di Re, defendant is left only with dicta. In Ker v. California (1963) 374 U.S. 23 [83 S.Ct. 1623, 10 L.Ed.2d 726] (Ker), a plurality of the high court observed that “the lawfulness of arrests for federal offenses is to be determined by reference to state law insofar as it is not violative of the Federal Constitution. [Citations.] A fortiori, the lawfulness of these arrests by state officers for state offenses is to be determined by California law.” (Id. at p. 37 [83 S.Ct. at p. 1632] (lead opn. of Clark, J.).) Since the police [613]*613had complied with California law (id. at p. 38 [83 S.Ct. at p. 1632]), the plurality’s observation was dictum.
In Michigan v. DeFillippo (1979) 443 U.S. 31 [99 S.Ct. 2627, 61 L.Ed.2d 343] (DeFillippo), the court stated that “whether an officer is authorized to make an arrest ordinarily depends, in the first instance, on state law.” (Id. at p. 36 [99 S.Ct. at p. 2631].) This statement is as true as it is unremarkable— state law “is relevant to the validity of the arrest and search only as it pertains to the ‘facts and circumstances’ we hold constituted probable cause for arrest.” (Id. at p. 40 [99 S.Ct. at p. 2633]; accord, Ryan v. County of DuPage (7th Cir. 1995) 45 F.3d 1090, 1093 [“the legality under the Fourth Amendment of an arrest for violating state law depends on that law in the following sense: there must be probable cause to believe that a state crime has been committed”].) In any event, this statement too was dictum, since (as the court immediately noted) “Respondent does not contend . . . that the arrest was not authorized by Michigan law.” (DeFillippo, supra, at p. 36 [99 S.Ct. at p. 2631].)
When we balance it against the forceful reasoning of Pennhurst, Elkins, Cooper, and Greenwood, we cannot accept the dicta in these two opinions as a pronouncement from the United States Supreme Court that compliance with state arrest procedures is a prerequisite to the validity of an arrest under the federal Constitution. Had the court intended to condition the constitutionality of an arrest on state law, it had ample opportunity to say so in Atwater. But Atwater nowhere rested its holding on the circumstance that Texas had by statute authorized a custodial arrest for a seatbelt offense. Indeed, the court’s announcement of its holding betrayed no reliance on state law: “If an officer has probable cause to believe that an individual has committed even a very minor criminal offense in his presence, he may, without violating the Fourth Amendment, arrest the offender.” (Atwater, supra, 532 U.S. at p. 354 [121 S.Ct. at p. 1557], italics added.)6
As for the federal courts of appeals, “[n]early every circuit to address the issue is in accord.” (U.S. v. Le (10th Cir. 1999) 173 F.3d 1258, 1264, [614]*614fn. 2.) The First,7 Second,8 Fourth,9 Fifth,10 Sixth,11 Seventh,12 Eighth,13 Ninth,14 and Tenth15 Circuits have each held that, once the officer has probable cause to believe a violation of law has occurred, the constitutionality of the arrest does not depend upon compliance with state procedures that are not themselves compelled by the Constitution. So have a number of state courts. (E.g., State v. Jolin (Me. 1994) 639 A.2d 1062, 1064 [“evidence obtained from an extraterritorial arrest based on probable cause should not per se be excluded”]; Commonwealth v. Lyons (1986) 397 Mass. 644 [492 N.E.2d 1142, 1144-1146] [refusing to suppress a photograph taken following an arrest that was illegal under state law]; People v. Burdo (1974) 56 Mich.App. 48 [223 N.W.2d 358, 360] [“defendant’s arrest was not constitutionally invalid, but rather merely statutorily illegal; therefore the per se exclusionary rule is not applicable” (fn. omitted)]; State v. Eubanks (1973) 283 N.C. 556 [196 S.E.2d 706, 709] [“We hold that nothing in our law requires the exclusion of evidence obtained following an arrest which is constitutionally valid but illegal for failure to first obtain an arrest warrant”]; State v. Droste (1998) 83 Ohio St.3d 96 [697 N.E.2d 620, 623] [“We have stated on many occasions that absent a violation of a constitutional right, the
[615]*615violation of a statute does not invoke the exclusionary rule”]; State v. Rodriguez (1993) 317 Or. 27 [854 P.2d 399, 409] [“Because the arrest in this case did not violate the Fourth Amendment, the guns discovered in the subsequent consent search were not subject to suppression under the Fourth Amendment, even if the arrest violated Article I, section 9, of the Oregon Constitution”]; Penn v. Commonwealth (1991) 13 Va.App. 399 [412 S.E.2d 189, 193-194] [“the fact that Virginia has adopted a more stringent statutory requirement for warrantless misdemeanor arrests committed outside the officer’s presence does not mean that Penn has acquired a constitutional right”], affd. (1992) 244 Va. 218 [420 S.E.2d 713]; but see State v. Martin (Minn. 1977) 253 N.W.2d 404, 405-406.)16
The majority view is sound. What would be gained, after all, by invoking the federal Constitution to exclude evidence seized following an arrest merely because, in violation of state law, a nonuniformed police officer failed to display a badge (e.g., Drewitt v. Pratt (4th Cir. 1993) 999 F.2d 774, 111 [the violation of Virginia law “did not rise to a violation of a federal constitutional magnitude”]), a uniformed officer effected an arrest beyond the officer’s territorial limit (e.g., People v. Wolf (Colo. 1981) 635 P.2d 213, 217-218 [denying the suppression motion “[d]espite the fact that the Denver police violated the statutes governing their authority to arrest”]), or a deputy’s commission suffered from technical administrative deficiencies (e.g., U.S. v. Jones (5th Cir. 1999) 185 F.3d 459, 462-463 [state law deficiency “does not affect our analysis” of the constitutional issue])? “The exclusionary rule was created to discourage violations of the Fourth Amendment, not violations of state law.” (U.S. v. Walker, supra, 960 F.2d at p. 415.) Constitutionalizing the myriad of technical state procedures that govern arrests would not only trivialize Fourth Amendment protections but would discourage states from even enacting such rules. (Cf. United States v. Caceres, supra, 440 U.S. at pp. 755-756 [99 S.Ct. at pp. 1473-1474].)
Against this array of authority, defendant has identified only one court that has excluded evidence under the authority of the federal Constitution for an officer’s failure to comply with state arrest procedures. In U.S. v. Mota, supra, 982 F.2d 1384 (Mota), the Ninth Circuit held that the failure of state [616]*616police officers to comply with state procedures rendered the arrest unreasonable under the Fourth Amendment and suppressed the fruits of a subsequent search incident to the arrest. (Id. at pp. 1388-1389.) The Mota brothers were arrested for operating a food cart without a business license in violation of a Santa Ana municipal ordinance. A search incident to arrest uncovered 41 counterfeit $20 bills. (Id. at pp. 1386-1387.) California law, however, did not authorize a custodial arrest for this infraction unless the arrestee had refused to present satisfactory evidence of identity or sign a written promise to appear. (Id. at pp. 1388-1389.)
In suppressing the evidence based on this violation of state procedure, the Ninth Circuit acknowledged its prior rulings that application of the exclusionary rule is a matter of federal law (Mota, supra, 982 F.2d at p. 1387) and that “in the context of a suit brought under 42 U.S.C. § 1983, . . . state law governing an arrest is irrelevant to determining whether the arrest deprived an individual of rights secured by the federal constitution or a federal statute” (ibid., citing Barry v. Fowler (9th Cir. 1990) 902 F.2d 770, 772 (Barry)). Conceding that other circuits had ruled otherwise, the court nonetheless deemed itself bound by Di Re, DeFillippo, and Ker (which it failed to note was a plurality opinion) to exclude the evidence. (Mota, supra, at pp. 1387-1388.) We find Mota unpersuasive.
First, as discussed above, Di Re, DeFillippo, and Ker do not constitutionalize state arrest procedures. Much more on point, we think, are Cooper and Greenwood (which were not cited in Mota) and Atwater (which was decided after Mota), all of which emphasize that state procedures are irrelevant to the Fourth Amendment inquiry.
Second, Mota’s holding that the custodial arrest was constitutionally unreasonable because it failed to comply with state procedure is utterly inconsistent with the Ninth Circuit’s earlier holding in Barry that “state law governing an arrest is irrelevant to determining whether the arrest deprived an individual of rights secured by the federal constitution or a federal statute.” (Mota, supra, 982 F.2d at p. 1387.)
Defendant attempts to reconcile these inconsistent rulings by quoting Professor LaFave as suggesting that the Ninth Circuit “might have more precisely said that though the arrest was constitutional despite the violation of state law, the incidental search was not because [United States v.] Robinson [(1973) 414 U.S. 218 [94 S.Ct. 467, 38 L.Ed.2d 427]] imposes as a prerequisite not just a constitutional arrest but, more demandingly, a ‘lawful custodial arrest.’ ” (1 LaFave, Search and Seizure, supra, § 1.5(b), p. 141.) What defendant fails to include is Professor LaFave’s cogent rebuttal to this [617]*617alternative interpretation: “[I]t must be asked whether the court was correct in reaching the essential conclusion that the Robinson test mandates ‘reference to state law governing the arrest.’ That is, when the Court in Robinson said ‘lawful custodial arrest,’ did the Court really mean an arrest which is lawfully custodial in a state law sense? Some of the Supreme Court’s language suggests otherwise. Just before the ‘lawful custodial arrest’ holding, there appears this sentence: ‘A custodial arrest of a suspect based on probable cause is a reasonable intrusion under the Fourth Amendment; that intrusion being lawful, a search incident to the arrest requires no additional justification.’ That seems to say that ‘lawful’ refers not to the limitations of state law but rather to an overarching principle that all it takes to make a custodial arrest reasonable in a Fourth Amendment sense is that it be based on probable cause. And thus it must be concluded that both of the alternative interpretations of the Mota holding are open to question.” (Id. at § 1.5(b), pp. 141-142; cf. United States v. Caceres, supra, 440 U.S. at pp. 751-755 [99 S.Ct. at pp. 1471-1473] [refusing to suppress taped conversations that were obtained in violation of Internal Revenue Service regulations that were not themselves compelled by the Constitution].)
Conditioning a search incident to arrest on the degree to which an otherwise constitutional arrest complies with state procedure, moreover, makes no sense. The justification for a search incident to arrest rests on “(1) the need to disarm the suspect in order to take him into custody, and (2) the need to preserve evidence for later use at trial.” (Knowles v. Iowa, supra, 525 U.S. at p. 116 [119 S.Ct. at p. 487].) Neither the need to disarm the suspect nor the need to preserve evidence depends upon the arrest’s compliance with state law.
Third, Mota’s reliance on Welsh v. Wisconsin (1984) 466 U.S. 740 [104 S.Ct. 2091, 80 L.Ed.2d 732] is misplaced. Welsh held that “an important factor to be considered when determining whether any exigency exists [to effect a warrantless arrest in the home] is the gravity of the underlying offense for which the arrest is being made.” (Id. at p. 753 [104 S.Ct. at p. 2099].) In that case, the offense was “a noncriminal violation” subject to a civil forfeiture proceeding. (Id. at p. 746 [104 S.Ct. at p. 2095].) Welsh, however, nowhere suggests that the validity of a warrantless arrest not based on exigent circumstances depends on a weighing of “the state’s assessment of the gravity of the offense justifying the arrest” or “the state’s expression of disinterest in allowing warrantless arrests for mere infractions.” (Mota, supra, 982 F.2d at pp. 1388-1389.) Any doubt on this score was resolved by Atwater, in which the court said: “we confirm today what our prior cases have intimated: the standard of probable cause ‘appliefs] to all arrests, without the need to “balance” the interests and circumstances involved in particular situations.’ ” (Atwater, supra, 532 U.S. at p. 354 [121 S.Ct. at p. 1557].)
[618]*618Last, MotcCs analogy between inventory searches and arrests is faulty. Mota sought guidance from another Ninth Circuit decision, U.S. v. Wanless (9th Cir. 1989) 882 F.2d 1459, which construed South Dakota v. Opperman (1975) 428 U.S. 364 [96 S.Ct. 3092, 49 L.Ed.2d 1000] and Colorado v. Bertine (1987) 479 U.S. 367 [107 S.Ct. 738, 93 L.Ed.2d 739] to require compliance with local police department procedures to uphold an inventory search. Leaving to one side the issue of whether the high court’s directive that inventory searches “be conducted according to standardized criteria” (Bertine, supra, 479 U.S. at p. 374, fn. 6 [107 S.Ct. at p. 742]) necessarily requires compliance to the letter with every local procedure, those cases cannot be read to undermine an arrest that—unlike an inventory search, an administrative inspection, or a random traffic stop—is justified by probable cause. (See Whren v. United States (1996) 517 U.S. 806, 811-812, 817-818 [116 S.Ct. 1769, 1773-1774, 1776-1777, 135 L.Ed.2d 89].) The absence of standardized local procedures is not fatal to an arrest or a search incident thereto. As the United States Supreme Court explained in upholding the search incident to an arrest for another minor traffic violation, “Though the officer here was not required to take the petitioner into custody by police regulations . . . and there did not exist a departmental policy establishing the conditions under which a full-scale body search should be conducted, we do not find these differences determinative of the constitutional issue. [Citation], It is sufficient that the officer had probable cause to arrest the petitioner and that he lawfully effectuated the arrest and placed the petitioner in custody.” (Gustafson v. Florida (1973) 414 U.S. 260, 265 [94 S.Ct. 488, 491-492, 38 L.Ed.2d 456] (Gustafson).)
In sum, we find Cooper, Elkins, Gustafson, Greenwood, and Atwater more persuasive and conclude that so long as the officer has probable cause to believe that an individual has committed a criminal offense, a custodial arrest—even one effected in violation of state arrest procedures—does not violate the Fourth Amendment. In this case, then, it is of no moment that defendant’s arrest assertedly violated the procedures set forth in section 40302(a) since (as defendant concedes) Deputy Valento had probable cause to believe defendant had violated a provision of the Vehicle Code.
By this decision, we in no way countenance violations of state arrest procedure. As we explained at the outset, Proposition 8 left intact the substantive scope of state statutory and constitutional rights against arrest for minor offenses. Violation of those rights exposes the peace officers and their departments to civil actions seeking injunctive or other relief. (Garrett v. City of Bossier City (La.Ct.App. 2001) 792 So.2d 24, 26-28 [although the arrest for a seatbelt offense was constitutional under Atwater, the arrest’s failure to comply with state procedure supported a private civil suit]; see [619]*619generally People v. Mayoff (1986) 42 Cal.3d 1302, 1318 [233 Cal.Rptr. 2, 729 P.2d 166] (plur opn. of Grodin, J.).) Violation of those state rights also may subject the offending officer to an internal investigation, additional training, and departmental discipline. (See Heffeman, Foreword: The Fourth Amendment Exclusionary Rule as a Constitutional Remedy (2000) 88 Geo. L.J. 799, 865 [“A direct sanction imposed on individual officers—internal police discipline, for example—is likely to channel police behavior into patterns of legal conduct far more effectively than does the indirect sanction of exclusion”].) What we cannot do, out of respect for the supremacy clause and Proposition 8, is “ ‘impose such greater restrictions as a matter of federal constitutional law when [the United States Supreme] Court specifically refrains from imposing them.’ ” (Arkansas v. Sullivan (2001) 532 U.S. 769, 772 [121 S.Ct. 1876, 1878, 149 L.Ed.2d 994], italics omitted, quoting Oregon v. Hass (1975) 420 U.S. 714, 719 [95 S.Ct. 1215, 1219, 43 L.Ed.2d 570].)
Moreover, by removing the threat that relevant evidence will be excluded for violation of their rules, our decision today may have the salutary effect of encouraging state and local governments as well as individual police departments to seize the opportunity Atwater presents to craft careful and detailed regulations governing the ability of officers to arrest for minor offenses. (See People v. Mayoff, supra, 42 Cal.3d at pp. 1318-1319; cf. County of Sacramento v. Lewis, supra, 523 U.S. atp. 841, fn. 5 [118 S.Ct. atp. 1714].) Thus, eliminating the sanction of exclusion does not mean that affected individuals or the public generally are without remedy against a wayward officer. “We, the judiciary, cannot claim that we and we alone wield the only power or possess the only wisdom to enforce rules.” (People v. Hoag (2000) 83 Cal.App.4th 1198, 1215 [100 Cal.Rptr.2d 556] (conc. opn. of Morrison, J.).)
Even if compliance with state procedure were a predicate to the constitutionality of defendant’s arrest under the Fourth Amendment, he still would not be entitled to relief in this proceeding, since (as we conclude) his arrest did not violate section 40302(a).
Our state law authorizes custodial arrests for violations of the Vehicle Code, but not in all circumstances. If the violation is declared to be a felony, the offender is to be dealt with in like manner “as upon arrest for the commission of any other felony.” (Veh. Code, § 40301; see Pen. Code, § 836.) For certain enumerated nonfelony offenses, the officer has the discretion to take the offender to “the nearest or most accessible” magistrate with jurisdiction over the offense or to issue a citation and, upon the offender’s signature of a promise to appear, release the offender. (§§ 40303, [620]*62040304.) For the remaining offenses (except driving under the influence), the officer must follow the cite-and-release procedure, unless the offender fails to present a driver’s license or other satisfactory evidence of identity for examination, refuses to give a written promise to appear in court, or demands an immediate appearance before a magistrate, in which case the officer must take the offender to the magistrate. (§ 40302; People v. Superior Court (Simon) (1972) 7 Cal.3d 186, 199-200 [101 Cal.Rptr. 837, 496 P.2d 1205].) The Legislature thus “in effect presumes that in the vast majority of cases the violator will not be taken into custody.” (Simon, supra, at p. 199.)
The parties agree that the arrest here is governed by section 40302, which states in pertinent part: “Whenever any person is arrested for any violation of this code, not declared to be a felony, the arrested person shall be taken without unnecessary delay before a magistrate within the county in which the offense charged is alleged to have been committed and who has jurisdiction of the offense and is nearest or most accessible with reference to the place where the arrest is made in any of the following cases: ffl] (a) When the person arrested fails to present his driver’s license or other satisfactory evidence of his identity for examination.” The parties disagree over whether Deputy Valento complied with this provision. The Attorney General argues that defendant’s custodial arrest was justified under section 40302(a) by his failure “to present his driver’s license or other satisfactory evidence of his identity for examination.” Defendant, on the other hand, argues that section 40302(a) cannot be used to justify his arrest because he told the officer his name and birthdate and thus provided “other satisfactory evidence of his identity.” This case therefore turns on the meaning of the requirement in section 40302(a) that the offender “present his driver’s license or other satisfactory evidence of his identity for examination.”
One part of the statute requires little construction. An offender may avoid a custodial arrest by presenting a driver’s license to the officer for examination. So long as the license is current, valid, and raises no suspicion that it has been altered or falsified, section 40302(a) does not require a custodial arrest. On this point, there is no dispute.
There is likewise no dispute that at least one category of identification qualifies as “other satisfactory evidence of . . . identity”—those forms of documentary evidence that are the functional equivalent of a driver’s license. This would include a state-issued identification card (§ 13005) and other current, reliable documentary evidence of identity that, like a driver’s license, bears the person’s photograph, physical description, current mailing address, and signature, and is serially or otherwise numbered. (See Veh. Code, § 12811; cf. Civ. Code, § 1185, subd. (c) [defining “‘satisfactory [621]*621evidence’ ” to identify the person acknowledging an instrument before a notary].)
Here, of course, defendant did not present a driver’s license or other documentary evidence of his identity. He contends, though, that “[n]othing in the code section provides that the person to be cited must present documentary evidence of his identity,” merely “satisfactory evidence of. . . identity.” Defendant offers an incomplete reading of the statute.
“ ‘In analyzing statutory language, we seek to give meaning to every word and phrase in the statute to accomplish a result consistent with the legislative purpose . . . .’” (California Teachers Assn. v. Governing Bd. of Rialto Unified School Dist. (1997) 14 Cal.4th 627, 634 [59 Cal.Rptr.2d 671, 927 P.2d 1175], quoting Harris v. Capital Growth Investors XIV (1991) 52 Cal.3d 1142, 1159 [278 Cal.Rptr. 614, 805 P.2d 873].) The statute here directs the offender to “present his driver’s license or other satisfactory evidence of his identity for examination.” (§ 40302, subd. (a), italics added; cf. Tenn. Code Arm. § 40-7-118(c)(3) [“No citation shall be issued under the provisions of this section if [¶] . . . [¶] . . . [t]he person arrested cannot or will not offer satisfactory evidence of identification . . . .”].) By the italicized language, the Legislature plainly contemplated that the evidence of identity be capable of presentation and examination, acts that are ordinarily performed on tangible objects. Prior to the 1968 amendment, this section permitted a custodial arrest “[w]hen the person arrested fails to exhibit his driver’s license or other satisfactory evidence of identity.” (Stats. 1963, ch. 1341, § 1, p. 2864, italics added.) The 1968 amendment (Stats. 1968, ch. 647, § 1, p. 1332) was “intended to clarify that either the driver’s license or identification must be given to the officer rather than merely exhibited, which in some instances has been complied with by showing it through a closed window. The license and identification must be examined to assure validity and the presence of license restrictions.” (Cal. Highway Patrol, Enrolled Bill Rep. on Assem. Bill No. 1122 (1968 Reg. Sess.) prepared for Governor Reagan (July 12, 1968), p. 1, italics added.)
This interpretation of section 40302(a)’s requirement that the offender “present” a license or other evidence of identity “for examination” is consistent with the Legislature’s use of this language in other statutes. (See Stillwell v. State Bar (1946) 29 Cal.2d 119, 123 [173 P.2d 313] [“it is a well-established rule of construction that when a word or phrase has been given a particular scope or meaning in one part or portion of a law it shall be given the same scope and meaning in other parts or portions of the law”].) Section 12951, subdivision (b), for example, provides that “[t]he driver of a motor vehicle shall present his or her license for examination upon demand [622]*622of a peace officer enforcing the provisions of this code.” Section 4462, subdivision (a) requires the driver to “present the registration or identification card or other evidence of registration of any or all vehicles under his or her immediate control for examination upon demand of any peace officer.” There can be little doubt that in both circumstances the driver is expected to surrender the specified document to the peace officer for examination, not merely to recite the information contained therein. When the Legislature uses the same language in section 40302(a), we can infer that the same result is intended.
By construing section 40302(a) in this manner, we do not intend to foreclose the exercise of discretion by the officer in the field in deciding whether to accept or reject other evidence—including oral evidence—of identification. It would be absurd to require an officer to effect a custodial arrest of an offender who is able to convince the officer, by any means, of his or her identity and willingness to appear in answer to the citation. An officer may, for example, be personally acquainted with the offender or obtain independent corroboration of the offender’s identity from others present. In these and other circumstances in which the officer is convinced of the offender’s identity, a custodial arrest would be unnecessary. We therefore hold that an officer has broad discretion to effect a custodial arrest under section 40302(a) unless the offender has presented a current and valid driver’s license or other reliable documentary evidence of identification.
The question then arises to what extent the officer’s exercise of discretion can be reviewed by a court. The mere fact that discretion has been entrusted to the officer, of course, does not warrant invalidation or revision of the statute. (U.S. v. Trigg (7th Cir. 1989) 878 F.2d 1037, 1041 [“The Court, however, has never indicated that the discretionary exercise of the arrest power, a power that is contingent upon a prior determination of probable cause, is constitutionally significant”].) Indeed, section 40303 leaves it completely to “the judgment of the arresting officer” whether to employ the cite-and-release procedure or to effect a custodial arrest for the offenses listed in subdivisions (a) through (q). Section 40304 does the same for non-Vehicle-Code traffic misdemeanors. Inasmuch as California could, consistent with the federal Constitution, authorize a custodial arrest for all Vehicle Code violations, the fact that it has delegated some discretion to police officers to evaluate the sufficiency of the proffered evidence of identity is, despite Justice Brown’s protestations (see cone. & dis. opn., post, at pp. 632, 635-636), of no constitutional concern. (See Gustafson, supra, 414 U.S. at p. 265 [94 S.Ct. at pp. 491-492].) As with all discretionary enforcement decisions, the officer’s choices may be challenged as being based on invalid criteria, such as race, religion, or other arbitrary classification, including the exercise of protected statutory or constitutional rights. [623]*623(See Wayte v. United States (1985) 470 U.S. 598, 608 [105 S.Ct. 1524, 1531, 84 L.Ed.2d 547].)17
Defendant interprets the statute to impose additional limits on an officer’s discretion. In his view, the officer should be required to conduct sufficient inquiries calculated to elicit satisfactory evidence of identity and to accept verifiable oral evidence of identity, and the officer’s failure to do so should be reviewed in the same manner as other police conduct under the Fourth Amendment. The fundamental problem with this interpretation, of course, is that the statute does not require the officer to act as defendant suggests. Rather, the statute plainly puts the burden of presenting satisfactory evidence of identity on the offender. Once the officer has made some inquiry that has put the offender on notice to produce evidence of his or her identity, the officer has done all that is required by the statute.
Moreover, defendant’s proposal that the officer be required to ask a specific set of questions would facilitate the use of false identities. If, as defendant asserts, requiring the officer to ask for the offender’s name, address, and date of birth “does not impose a heavy or unreasonable burden on the officer in the field,” it follows that the unscrupulous offender could just as easily memorize those three bits of information, parrot it back to the officer, and thus evade responsibility for any number of Vehicle Code offenses, since the physical description available through a computer database may well be too general to adequately confirm the offender’s identity. (See Lee v. Superior Court (2000) 22 Cal.4th 41, 43 [91 Cal.Rptr.2d 509, 989 P.2d 1277] [petitioner evaded traffic citation by falsely identifying himself, as his deceased brother]; accord, Cal. Highway Patrol, Enrolled Bill Rep. on Assem. Bill No. 219 (1995-1996 Reg. Sess.) prepared for Governor Wilson (July 3, 1995) p. 1 [“there have been several occasions where individuals have misrepresented themselves when they did not have photographic identification to substantiate their identity”].) If, on the other hand, the essential litany of questions is left undefined, then the officer is without guidance as to the number of questions that should be sufficient to elicit satisfactory evidence of identity or the quantum of evidence that an officer should know would be sufficient to establish identity in each instance. Case-by-case adjudication to flesh out the prerequisites for compliance with section 40302(a) does not properly credit the state’s “essential interest in readily administrable rules” or comply with the high court’s directive “to draw standards sufficiently clear and simple to be applied with a fair prospect of surviving judicial second-guessing months and years after an arrest or search is made.” (Atwater, supra, 532 U.S. at p. 347 [121 S.Ct. at pp. 1553-1554].)
[624]*624We likewise conclude that the statute does not support judicial oversight of officer discretion beyond what we have articulated above. (See People v. Superior Court (Simon), supra, 7 Cal.3d at p. 201 [“At the very least, he must be able to convince the officer . . . [of] his true identity .... When he cannot do so the officer has no assurance the promise will be honored, and under those circumstances subdivision (a) prohibits the use of the citation procedure.” (Italics added.)].) Unlike the cases meriting application of the exclusionary rule, an officer acting under section 40302(a) is hardly engaged in “ ‘ “the often competitive enterprise of ferreting out crime.” ’ ” (People v. Amador (2000) 24 Cal.4th 387, 396 [100 Cal.Rptr.2d 617, 9 P.3d 993].) Indeed, it is in the interest of the police to limit petty-offense arrests, which carry costs that are simply too great to incur without good reason. (Atwater, supra, 532 U.S. at p. 352 [121 S.Ct. at p. 1556]; accord, People v. Grant (1990) 217 Cal.App.3d 1451, 1455 [266 Cal.Rptr. 587] [describing the California Highway Patrol’s policy against custodial arrests when the driver merely fails to carry a license while driving].) Defendant’s complaint that “an officer should not be able to ignore readily available proof of identity” overlooks the fact that the officer has no incentive to do so.
It is one thing for a court to review an officer’s decision to reject a driver’s license or other documentary evidence of identification, since the item itself can be brought to the magistrate to support the officer’s belief it had been altered or falsified. It is quite another to review an officer’s decision to reject oral evidence of identification, since that decision will be based entirely on the officer’s assessment of the offender’s credibility—an assessment involving intangible factors that may be difficult to reproduce in the courtroom. There is a world of difference in making that judgment as a matter of discretion “and making the same judgment when the question is the lawfulness of the warrantless arrest itself. It is the difference between no basis for legal action challenging the discretionary judgment, on the one hand, and the prospect of evidentiary exclusion or . . . personal [42 United States Code] § 1983 liability for the misapplication of a constitutional standard, on the other.” (Atwater, supra, 532 U.S. at p. 350 [121 S.Ct. at p. 1555].)
Furthermore, transferring the locus of discretion from the officer in the field to the courtroom, as defendant suggests, would have perverse results. Under section 40302(a), a custodial arrest is mandatory when the offender fails to present a driver’s license or other satisfactory evidence of identity. Under our construction of the statute, which reserves wide discretion to the officer to determine what evidence is satisfactory, the officer is authorized to use the cite-and-release procedure whenever the officer is satisfied with the evidence of identity the offender has presented. If, instead, the determination [625]*625of what evidence is satisfactory will be made by the magistrate under the case law as it evolves, the officer will be compelled by section 40302(a) to effect a custodial arrest whenever the evidence offered by the offender does not meet the standard set forth in the case law—even if the officer is otherwise convinced of the offender’s identity.
Defendant’s final argument is not without some initial commonsense appeal: “If a person is not required by law to carry identification, he cannot be constitutionally arrested for not doing so.” The flaw in defendant’s argument, though, is that he was not arrested because of his failure to carry identification. Rather, he was arrested for committing a Vehicle Code infraction. A bicyclist is subject to all provisions of the rules of the road “applicable to the driver of a vehicle” (§ 21200, subd. (a)) and is subject as well to division 17 of the Vehicle Code, which includes section 40302. (§§ 231, 21200, subd. (a).) Here, of course, defendant was not arrested merely because he failed to produce a license. He was arrested because he violated the Vehicle Code. At that point, the need to obtain reliable evidence of identification and ensure compliance with a promise to appear is equally great for a bicyclist as for a driver of a motorized vehicle. Although only the latter is obligated to have a license in his or her possession at all times while driving on the road (§ 12951, subd. (a)), both are required to produce satisfactory evidence of identity for examination when stopped for a violation of the law. If enforcement of those laws duly enacted by the Legislature is to occur, it could hardly be otherwise. (See People v. Mercurio (1970) 10 Cal.App.3d 426, 430 [88 Cal.Rptr. 750] [“The statute obviously is designed to insure that the violator will be held personally responsible for a Vehicle Code violation”].)
In sum, section 40302(a) entrusts the decision whether to accept nondocumentary evidence of identity to the discretion of the arresting officer. Because defendant makes no showing that Deputy Valento exercised his discretion in an unconstitutional manner, the arrest did not violate the statute.
