Justice LOHR
delivered the Opinion of the Court.
This case arises out of an airplane accident and presents issues concerning the scope of the “inherently dangerous activity” exception to the rule that one who employs an independent contractor is not liable for torts committed by the independent contractor or its servants. In an action by the children of a passenger killed in a crash of a single engine plane against Union Rural Electric Association (UREA), which engaged a contract flight service to make the wintertime mountain flight that resulted in the passenger’s death, the district court entered judgment for the plaintiffs based on a jury verdict. The Colorado Court of Appeals reversed and directed that the action be dismissed. Huddleston v. Union Rural Elec. Ass’n, 821 P.2d 862 (Colo.App.1991). The court held that as a matter of law the activity of the contractor was not inherently dangerous and that the district court therefore erred ,in denying the motion of UREA for a directed verdict. Id. We granted certiorari and now reverse and remand for a new trial.
I
Some of the pertinent facts have been stipulated, and others appear in the record without contradiction. UREA is a rural electric cooperative corporation that supplies power to customers in certain Colorado counties along the front range. Early in 1987, legislation proposed by UREA was pending in the Colorado General Assembly, and UREA had hired an organization of [285]*285which James Huddleston was a part to provide lobbying services. In furtherance of the effort to secure passage of the legislation, UREA wished to seek the support of other rural electric cooperatives. One such organization was San Miguel Power Association, which served certain areas on Colorado’s western slope. At least a week before a meeting of the board of directors of San Miguel Power Association scheduled for January 28, 1987, in Nucía, Colorado, UREA’s executive secretary called Charles L. Brooks, who operated a charter airplane service, and arranged for him to transport UREA representatives to the meeting. They agreed on the use of a single engine aircraft. On January 28, Brooks piloted a single engine Cessna aircraft on a trip from the Jefferson County airport, with Nucía as the destination. On board were two directors of UREA and James Huddle-ston. The plane subsequently crashed into a mountain near Nucía killing all occupants of the aircraft.1
Judith Huddleston, the wife of decedent James Huddleston, brought this action in Boulder County District Court as parent and next friend of the couple’s two children, Jami N. Huddleston and Jenifer B. Huddleston. The plaintiffs asserted a claim for negligent hiring of pilot Brooks and also asserted that UREA was accountable for Brooks’ negligence on the basis of respondeat superior because the activity in which Brooks was engaged was “inherently dangerous,” thereby qualifying for an exception to the general rule that an employer of an independent contractor is not liable for injuries resulting from the negligence of the contractor.2
UREA moved to dismiss the claim grounded on respondeat superior on the basis that as a matter of law “aviation is not inherently dangerous and the operation of a charter service does not subject the party who charters the plane to vicarious liability.” As part of the same motion, UREA sought summary judgment on the negligent hiring claim. The district court granted the motion for summary judgment on the negligent hiring claim.3 It concluded, however, that it could not find as a matter of law that the activity in question was not inherently dangerous, and therefore denied the motion to dismiss the re-spondeat superior claim.
The case was tried to a jury. Prior to trial, the parties stipulated that the crash that caused the death of James Huddleston occurred as a direct and proximate result of the negligence of Brooks. They also stipulated that Brooks was an independent contractor and not an employee of UREA.4
After presentation of all the evidence, UREA moved for a directed verdict, again asserting that as a matter of law the activity in which Brooks was engaged was not inherently dangerous. The district court denied the motion, and the jury subse[286]*286quently returned a verdict for the plaintiffs in the amount of $525,000. The court entered judgment against UREA based on the jury verdict.
UREA appealed to the Colorado Court of Appeals. The court held that “the proper test to determine whether an activity is ‘inherently dangerous’ is whether danger ‘inheres’ in performance of the activity no matter how skillfully performed” and that “if there is a way to perform the ... activity without danger, ... then the activity is not ‘inherently dangerous.’ ” Huddleston, 821 P.2d at 864 (citations omitted). Relying on the proposition that construction of a contract is a matter of law for a court to decide, the court then defined the activity for which Brooks was hired according to its interpretation of the agreement between Brooks and UREA. Id. at 865. It found that the parties had agreed that Brooks would safely transport Huddleston to Nuc-ía by a single engine airplane, and that Brooks was not required by contract to proceed with the flight in the event of adverse weather conditions. Id. at 866. Taking notice that air transportation, in general, is far safer than automobile transportation, and applying what it found to be the proper test for determining whether an activity is inherently dangerous, the court held that reasonable minds had to agree that the contracted-for activity was not inherently dangerous. Id. Therefore, according to the court of appeals, “UREA was not vicariously liable under the ‘inherent danger’ exception to the general rule of employer non-liability,” and the district court erred in denying UREA’s motion for a directed verdict. Id.
We granted certiorari to review the court of appeals’ judgment, and now hold that the court of appeals erred both by applying an incorrect test to determine whether an activity is inherently dangerous and by defining that activity only or primarily according to its interpretation of the independent contractor’s contractual obligations. We further hold that the plaintiffs produced sufficient evidence at trial to create an issue of fact for the jury as to whether all the elements of the “inherently dangerous activity” exception to the general rule of nonliability for the negligence of an independent contractor were proven by a preponderance of the evidence. However, because the jury instructions did not adequately apprise the jury of the elements of the inherently dangerous activity exception, we remand to the court of appeals with directions that it order a new trial in this case.

In Western Stock Center, Inc. v. Sevit, Inc., 195 Colo. 372, 578 P.2d 1045 (1978), we again recognized the “inherently dangerous activity” exception to the general rule that employers of independent contractors are not liable for the torts of their contractors. Id. at 378, 578 P.2d at 1050. See Garden of the Gods Village v. Hellman, 133 Colo. 286, 295, 294 P.2d 597, 602 (1956). We now reaffirm the inherently dangerous activity exception5 and further [287]*287articulate guidelines for its application. We consider first the policy objectives behind the exception and then the legal bases from which the exception is derived. We conclude that the court of appeals misinterpreted the exception in this case.
A
The inherently dangerous activity exception is based on two primary policy concerns. The first is that employers whose enterprises directly benefit from the performance of activities that create special and uncommon dangers to others should bear some of the responsibility for injuries to others that occur as a result of the performance of such activities. See Fleming James, Jr., Vicarious Liability, 28 Tul.L.Rev. 161, 169-70, 172 (1954) (explaining that a policy behind vicarious liability in general has been that those for whose benefit and at whose direction risks are imposed on others should share the cost of losses incurred as a result of such risks).6 This accords with basic intuitions of fairness, and it is also consistent with what is often efficient economically.7 The second is that it is sound public policy with regard to inherently dangerous activity “to have another layer of concern in order to try to ensure that activity that is inherently dangerous gets enough attention so that we reduce the number of people who are injured.” Tr. at 158-59, Huddleston v. Union Rural Electric Ass’n (Boulder County Dist.Ct. Feb. 6, 1990) (No. 88CV2012) (Bellipanni, J., ruling from the bench on defendant’s motion for a directed verdict). In other words, with regard to inherently dangerous activities, it is desirable that employers have an added incentive to encourage their independent contractors to take all reasonably feasible precautions against injury to others.
B
As a general rule, a person hiring an independent contractor to perform work is not liable for the negligence of the independent contractor. E.g., Thayer v. Kirchhof, 83 Colo. 480, 484, 266 P. 225, 226-27 (1928); see Restatement (Second) of Torts § 409 (1964). In Garden of the Gods, however, this court adopted the widely recognized rule that “[wjhen work to be done is dangerous in itself, or is of a character inherently dangerous unless proper precautions are taken, an employer cannot evade liability by engaging an independent contractor to do such work.” Garden of the Gods, 133 Colo. at 295, 294 P.2d at 602. In Western Stock, we drew upon section 427 of the Restatement (Second) of Torts and [288]*288described an inherently dangerous activity as one “ ‘involving a special danger to others which the employer knows or has reason to know to be inherent in or normal to the work,'” Western Stock, 195 Colo. at 378, 578 P.2d at 1050 (quoting from section 427 of the Second Restatement), but then added, somewhat paradoxically, that the work or activity “must only present a foreseeable and significant risk of harm to others if not carefully carried out.” Id. We now are persuaded that Western Stock does not adequately identify the legal criteria by which to determine whether an activity may properly be characterized as “inherently dangerous” for purposes of the rule of vicarious liability. Instead of relying solely upon Western Stock as the standard for resolving whether an activity is inherently dangerous, we must therefore look to several provisions of the Restatement (Second) of Torts and related case law to supply the appropriate analytical framework for answering that question.
Section 427 of the Restatement (Second) of Torts carves out a limited exception to the general rule of nonliability for the negligence of an independent contractor by providing as follows:
One who employs an independent contractor to do work involving a special danger to others which the employer knows or has reason to know to be inherent in or normal to the work, or which he contemplates or has reason to contemplate when making the contract, is subject to liability for physical harm caused to such others by the contractor’s failure to take reasonable precautions against such danger.
(Emphasis added.) As framed, section 427 creates a rule of vicarious liability making the employer liable for the negligence of the independent contractor in failing to guard against a special danger, irrespective of whether the employer has itself been at fault. See Restatement (Second) of Torts, introductory note at 394. However, this rule of vicarious liability “applies only where the harm results from the negligence of the contractor in failing to take precautions against the danger involved in the work itself, which the employer should contemplate at the time of his contract,” id. § 427 cmt. d, and does not apply “where the negligence of the contractor creates a new risk, not inherent in the work itself or in the ordinary or prescribed way of doing it, and not reasonably to be contemplated by the employer.” Id. Section 427, in other words, does not apply to the “ ‘collateral negligence,' ” id., of the independent contractor, where “collateral negligence”8 means the following: It is negligence of the independent contractor that occurs after the independent contractor has departed from the ordinary or prescribed way of doing the work, when such departure is not reasonably to have been contemplated by the employer, and when such negligence would not have occurred but for such a departure. In the event that such a departure is by itself a negligent act or omission on the part of the independent contractor, that too is “collateral negligence.” What is common in either case is that “collateral negligence” is negligence not reasonably to have been contemplated by the employer, [289]*289in contrast to negligence reasonably to have been contemplated as a recognizable risk associated with the ordinary or prescribed way of doing the work under the circumstances.
Although the comments to section 427 of the Restatement (Second) of Torts do not define “special danger,” id. § 427, helpful insight into the meaning of this term can be gleaned from other sections of the Restatement, such as section 416, which is closely related to section 427 and represents a different form of the same general principle stated in section 427. See id. § 416 cmt. a. Section 416 of the Restatement (Second) of Torts states:
One who employs an independent contractor to do work which the employer should recognize as likely to create during its progress a peculiar risk of physical harm to others unless special precautions are taken, is subject to liability for physical harm caused to them by the failure of the contractor to exercise reasonable care to take such precautions, even though the employer has provided for such precautions in the contract or otherwise.
(Emphasis added.) Comment d to section 416 defines a “peculiar risk” as “a risk differing from the common risks to which persons in general are commonly subjected by the ordinary forms of negligence which are usual in the community.”
Comment b to section 416 incorporates by reference comment b to section 413 with respect to the meaning of both “peculiar risk” and “special precautions.”9 When these comments are read together, it is clear that the independent contractor’s failure to take precautions against an ordinary or customary danger does not create the type of “special or peculiar danger” to which the “inherently dangerous” activity exception applies. Id. § 413 cmt. b. Rather, it is the work itself, or the particular circumstances under which the work is to be performed, that must create the special type of danger that is not ordinarily present in the type of activities to which persons are generally subjected in the community. See, e.g., Wilson v. Good Humor Corp., 757 F.2d 1293, 1304 (D.C.Cir.1985) (inherent danger depends on the nature of the work and the fact-specific circumstances under which the work is to be performed); Stark v. Weeks Real Estate, 94 Cal.App.3d 965, 156 Cal.Rptr. 701, 705 (1979) (peculiar risk is a risk peculiar to the work to be done and arises out of its character and place of performance); Lunde v. Winnebago Indus., Inc., 299 N.W.2d 473, 476 (Iowa 1980) (the peculiar risk must inhere in the work itself as performed in its usual or normal manner); Reilly v. Highman, 185 Kan. 537, 345 P.2d 652, 656 (1959) (contemplated conditions under which the work is to be done and the known circumstances attending it are important considerations in determining whether work constitutes an inherently dangerous activity). For purposes of the “inherently dangerous” activity exception, therefore, the focus is on dangers recognizable in advance or contemplated by the [290]*290employer as being “inherent” in the activity, or the. circumstances of performance, when carried out in its ordinary way, and not on risks created by or following from the contractor’s unforeseeable departure from the ordinary or prescribed way of performing the work under the circumstances.
Against this backdrop of the Restatement (Second) of Torts and related case law, we conclude that an activity will qualify as “inherently dangerous" when it presents a special or peculiar danger to others that is inherent in the nature of the activity or the particular circumstances under which the activity is to be performed, that is different in kind from the ordinary risks that commonly confront persons in the community, and that the employer knows or should know is inherent in the nature of the activity or in the particular circumstances under which the activity is to be performed. In addition, although an activity may be inherently dangerous, an employer will not be liable for injuries caused by the collateral negligence of its independent contractor in performing that activity.
C
The court of appeals held that because the activity for which Brooks was hired could have been performed without danger, such activity could not have been inherently dangerous. Huddleston, 821 P.2d at 866. Accord id. at 864 (“[T]he proper test to determine whether an activity is ‘inherently dangerous’ is whether danger ‘inheres’ in performance of the activity no matter how skillfully performed” and “if there is a way to perform the ... activity without danger, ... then the activity is not ‘inherently dangerous.’ ”) (citations omitted).
This, however, is not the correct test, for an activity may be inherently dangerous even if it can be performed safely by taking proper precautions, Restatement (Second) of Torts § 427 cmt. b (“[i]t is not ... necessary to the employer’s liability that the work be of a kind which cannot be done without a risk of harm to others”). In other words, the court of appeals erred by selecting a test that requires an activity to be more dangerous than it needs to be in order to be classified as inherently dangerous for the purpose of applying the inherently dangerous activity exception to the general rule that employers are not liable for the torts of their independent contractors.10
Ill
Once the correct standard by which to determine whether an activity is inherently dangerous has been identified, it is still necessary to define the activity to which that standard should be applied. The court of appeals took the approach that the activity to which the standard is to be applied should be defined by the independent contractor’s contractual obligations to the em[291]*291ployer, and that, therefore, the definition of the activity in question is a matter of the interpretation of a contract. As we shall explain, this approach is flawed because it fails to recognize that when the inherently dangerous activity exception applies and the negligence of the independent contractor is not collateral to the work, the law invokes the theory of respondeat superior, according to which an employer may be liable for the tort of its agent even if the agent acted in violation of the employer’s express instructions. See infra part III B. But before we do that, the decision of the court of appeals also raises an issue regarding the interpretation of oral contracts which, although we need not resolve it, deserves comment in order to obviate the potential for confusion. See infra part III A.
The court of appeals thought that “[t]he issue before [it was] ... whether the specific terms and details of the contracted activity were ... in dispute based on the evidence and, if not, whether reasonable minds could differ on whether ... the contracted activity was ‘inherently dangerous.’ ” Huddleston, 821 P.2d at 865. In taking that approach, the court began with a rule that “inasmuch as contract construction is a matter of law, the appellate court is not bound by the findings and conclusions of the trial court.” Id. (citing Buckley Bros. Motors, Inc. v. Gran Prix Imports, Inc., 633 P.2d 1081 (Colo.1981)). In Gran Prix Imports, however, we were faced with the interpretation of a writing, and our holding was that “the determination of ambiguity in a document is a question of law and ... this court is not bound by the findings of the trier of fact.” Gran Prix Imports, 633 P.2d at 1083 (emphasis added). Accord Fibreglas Fabricators, Inc. v. Kylberg, 799 P.2d 371, 374 (Colo.1990) (“Interpretation of a written contract and the determination of whether a provision in the contract is ambiguous are questions of law, and this court need not defer to the trial court’s interpretation of the contract.”) (emphasis added); Pepcol Mfg. Co. v. Denver Union Corp., 687 P.2d 1310, 1313 (Colo.1984) (“Interpretation of a written contract is generally a question of law for the court.”) (emphasis added).
In contrast with Gran Prix Imports, Pepcol, and Fibreglas Fabricators, there is no evidence in this case that there is a document to interpret or that there ever was a written agreement between Brooks and UREA concerning the flight to Nucia.11 Furthermore, this court has not yet ruled on the specific and proper allocation of functions between the court and a jury when the issue is the interpretation or construction of a purely oral agreement.12 [292]*292Nor need we reach today the issues of whether the court of appeals correctly took it upon itself to construe the oral agreement or whether, when faced with construing the agreement, the court of appeals interpreted it correctly. Instead, we simply start with the assumption, without expressing any opinion on the matter, that the court of appeals correctly determined that there was a contract between Brooks and UREA, that the contract required “that Brooks safely transport Huddleston and two UREA board members from Jefferson County to Nucia on January 28, 1987,” Huddleston, 821 P.2d at 866 (emphasis added), and that it “was not a condition of the contract that Brooks proceed with the flight regardless of existing weather conditions.” Id.
In Western Stock, we held that when the inherently dangerous activity exception is applicable, “ ‘the law invokes the theory of respondeat superior, imposing the master-servant relationship upon the parties engaged in the activity.’ ” Western Stock, 195 Colo. at 378, 578 P.2d at 1050 (quoting Epperly v. City of Seattle, 65 Wash.2d 777, 399 P.2d 591 (1965)). Under the theory of respondeat superior, “[a]n employer may be held responsible for tortious conduct by an employee only if the tort is committed within the course and scope of employment.” Destefano v. Grabrian, 763 P.2d 275, 286 (Colo.1988). Generally, “[a]n employee is acting within the scope of his employment if he is engaged in the work which has been assigned to him by his employer or he is doing what is necessarily incidental to the work which has been assigned to him or which is customary within the business in which the employee is engaged.” Id. at 287. Moreover, it is widely recognized that “[i]f the tortious act is within or incident to an employee’s authorized duties, the employer is liable even if the employee acted in violation of the employer’s instructions.” Fahey v. Rockwell Graphic Systems, Inc., 20 Mass.App.Ct. 642, 482 N.E.2d 519, 527 (1985), rev. denied, 396 Mass. 1103, 485 N.E.2d 188 (1985).13 In short, “[a]n act, although forbidden, or done in a forbidden manner, may be within the scope of employment,” Restatement (Second) of Agency § 230 (1958), and “[a] master cannot avoid responsibility for the negligence of a servant by telling him to act carefully.” Id. § 230 cmt. b.
In the case before us, therefore, it is not dispositive if UREA’s agreement [293]*293with Brooks required that Brooks carefully or safely transport Huddleston to Nucía aboard a single engine plane. Rather, if the negligence of Brooks occurred while Brooks was acting within the scope of the work for which he was hired, and if the negligence was not collateral to that work, then, if it was recognizable to UREA that the work as performed would be inherently dangerous, even if the negligence of Brooks violated his contractual obligations and UREA’s express instructions, UREA would still be liable under the inherently dangerous activity exception for injuries directly and proximately caused to third persons by such negligence.14 If this were not the rule, an employer could always avoid liability under the inherently dangerous activity exception simply by inserting into its agreements standard language to the effect that its independent contractor promises to perform safely and to take all necessary precautions. Consequently, when determining whether the work that an independent contractor was hired to perform was inherently dangerous, the trier of fact must take into account more than just the manner in which an oral or written contract legally obligates the contractor to perform such work. The important point is that while an independent contractor may have a legal obligation to take a particular precaution as a matter of contract law, as a matter of fact the employer may nevertheless know or contemplate, or may nevertheless have reason to know or to contemplate, that the work to be performed is inherently dangerous. The court of appeals erred, therefore, insofar as it defined the activity in question only or primarily according to the terms of Brooks’ contractual obligations, rather than in terms of what, as a matter of fact, UREA knew or had reason to know about the type of dangers associated with the work it was hiring Brooks to perform. Cf. Ballinger v. Gascosage Elec. Coop., 788 S.W.2d 506, 511 (Mo.1990) (explaining that under the inherently dangerous activity exception, the employer “remains liable for the torts of the contractor[] simply for commissioning the activity. The liability attaches without any need for showing that the employer is in any respect negligent. It is purely vicarious.”) (overruled by Zueck v. Oppenheimer Gateway Properties, 809 S.W.2d 384, 390 (Mo.1991), but only to the extent that Ballinger also holds that the inherently dangerous activity exception applies to employees of independent contractors covered by workers’ compensation).
IV
Having determined that the court of appeals erred in its definition of inherently dangerous activity, and that it also erred by applying that definition to an activity defined only or primarily according to an interpretation of Brooks’ contractual obligations, we now address whether the plaintiffs produced sufficient evidence at trial to create an issue of fact for the jury as to whether all the elements of the inherently dangerous activity exception were proven by a preponderance of the evidence.
We acknowledge that the determination of whether an activity is inherently dangerous will ultimately depend on the state of the evidence bearing on that issue. Depending on the state of the evidence, a court may or may not be required to rule as a matter of law that the activity does or does not qualify as inherently dangerous. See generally Kopeikin v. Merchants Mortgage and Trust Corp, 679 P.2d 599, 601 (Colo.1984); Gossard v. Watson, 122 Colo. 271, 275, 221 P.2d 353, 356 (1950). If the state of the evidence is such that when viewed in a light most favorable to the [294]*294plaintiff, the court is convinced that a jury could not find that all the following elements have been proven by a preponderance of the evidence, then it should direct a verdict against the plaintiff and in favor of the employer: (1) that the activity in question presented a special or peculiar danger to others inherent in the nature of the activity or the particular circumstances under which the activity was to be performed; (2) that the danger was different in kind from the ordinary risks that commonly confront persons in the community; (3) that the employer knew or should have known that the special danger was inherent in the nature of the activity or in the particular circumstances under which the activity was to be performed; and (4) that the injury to the plaintiff was not the result of the collateral negligence of the defendant’s independent contractor. Of course, if a jury could reasonably find from the evidence, when viewed in the light most favorable to the plaintiff, that all of the above elements have been proven by a preponderance of the evidence, then the issue of whether the activity is inherently dangerous should be submitted to the jury.
At trial, the plaintiffs’ expert witness on aviation testified that in light of the particular circumstances surrounding the flight in question, it was his opinion that the flight was “very dangerous” if it was not carefully carried out. The jury also heard evidence to the effect that Brooks was hired to fly a single engine airplane, that such an airplane was unpressurized and uncertified for flights into icy conditions, that flying in the Colorado mountains safely in the wintertime requires a skilled understanding of sometimes difficult and unpredictable weather patterns, that the airport at Nucía did not have a Federal Aviation Administration approved instrument approach procedure, that Brooks filed an instrument flight plan, and that representatives of UREA took into consideration the risk involved in flying a small plane in the wintertime in the mountains of Colorado. The jury also heard evidence to the effect that the type of aircraft flown by Brooks is a good, reliable “work horse type airplane” capable of safely flying in Colorado all year around under proper conditions. There was no evidence introduced that, in general, Brooks was not a capable pilot.
We are satisfied that contracting with a charter airplane service to fly passengers in the wintertime is not per se an inherently dangerous activity. However, when the evidence bearing on the particular circumstances under which the flight was to be performed in this case is viewed in a light most favorable to the plaintiff, we are also convinced that the evidence created an issue of fact for the jury as to whether all the elements of the “inherently dangerous activity” exception to the general rule of nonliability for the negligence of an independent contractor were proven by a preponderance of the evidence.
V
Our last step is to consider whether the jury was properly instructed on the meaning of “inherently dangerous activity,” and on how to apply that concept in this case. We conclude that it was not.
Understandably, the trial court relied heavily on the precise language employed in Western Stock (part of which we characterize today as “somewhat paradoxical”) and was reluctant even to attempt to dissect into its individual elements the meaning of section 427 of the Restatement (Second) of Torts. As a result the jury was not instructed to consider separately any of the elements of the inherently dangerous activity exception that we identify today, and the jury was given no instruction at all on the issue of whether the accident was caused by the collateral negligence of Brooks. The jury instructions in this case were therefore “ ‘so erroneous or so confusing or misleading as probably to lead the jury into error of such proportion as to require a new trial.’ ” Rego Co. v. McKown-Katy, 801 P.2d 536, 539 (Colo.1990) (quoting Coleman v. United Fire and Casualty Co., 767 P.2d 761, 764 (Colo.App.1988)).15
[295]*295VI
For the foregoing reasons, we reverse the judgment of the court of appeals and remand to that court with directions to order a new trial.
