PALLADINO, Judge.
Joan and Giovanni Misc. and Lorraine and Anthony Cifelli, Sr., individually and as parents and natural guardians of [266]*266minors Anthony Cifelli, Jr. and Christina Cifelli (collectively, Claimants) appeal that portion of the September 25, 1990 order of the Court of Common Pleas of Luzerne County (trial court) which granted summary judgment in favor of Ross Township Police Department (Township) and dismissed Township as a defendant. We affirm.
On December 20, 1985, Claimants filed a complaint against Township seeking compensation for injuries which Claimants received in a February 3, 1984 motor vehicle accident on a section of state-designated highway Route 118 which was within the physical boundaries of Ross Township.1
The complaint alleged that Claimants’ injuries were caused by Township’s negligence in:
(a) Failing to post or place flares, warning signs or lights, or other traffic control devices sufficient to warn oncoming traffic of the icy roadway and of the existence of the vehicles blocking the roadway;
(b) Failing to block the roadway or otherwise prevent traffic from using the roadway made dangerous by its icy condition;
(c) Allowing vehicles assisting at the site of the earlier accident to park on the roadway and block off the lanes of travel without allowing a lane of travel for oncoming vehicles.
Claimants’ Complaint, paras. 46 and 47, at R. 9a-10a.
Pursuant to Pa.R.C.P. No. 1035, Township, after depositions and interrogatories, filed a motion for summary judgment based on Township’s immunity from suit. Claimants relied on the exception to governmental immunity at 42 Pa.C.S. § 8542(b)(4), i.e., dangerous condition of traffic signs, lights or other traffic controls under the care, custo[267]*267dy or control of Township. On September 25,1990, the trial court issued an opinion and order which granted summary judgment to Township, and from which Claimants appeal.
Our scope of review is limited to determining whether the trial court committed an error of law or abused its discretion in entering summary judgment. Peters Township School Authority v. United States Fidelity and Guaranty Co., 78 Pa.Commonwealth Ct. 365, 467 A.2d 904 (1983). Claimants’ appeal raises two issues: (1) whether the trial court erred in granting summary judgment to Township because Claimants failed to allege facts sufficient to support a cause of action in negligence against Township, see 42 Pa.C.S. § 8542(a), and therefore Township’s actions could not fall within the exception to governmental immunity at subsection 8542(b)(4), and (2) whether the trial court abused its discretion by denying the request of Claimants for leave to amend their complaint so that Claimants could amplify their factual allegations against Township and thereby attempt to avoid summary judgment in favor of Township.
I. Summary Judgment Standards
As explained in Peters Township School Authority,
[a] summary judgment may be properly entered only where the moving party has established that there remains no genuine issue of material fact and that it is entitled to judgment as a matter of law____ In determining whether to enter a summary judgment, a court must view the record in the light most favorable to the non-moving party____ The moving party’s burden to prove that its right to a summary judgment is clear and free from doubt is a heavy one.
Id., 78 Pa.Commonwealth Ct. at 369, 467 A.2d at 906; accord Pa.R.C.P. No. 1035(b).
On appeal, Claimants have not asserted any disputes as to the facts material to a resolution of this case. 2 Claimants [268]*268contend that the trial court’s entry of summary judgment in favor of Township was improper because, pursuant to the principles of governmental immunity enunciated in what is commonly called the Political Subdivision Torts Claim Act (Act), 42 Pa.C.S. §§ 8541-8564, Township was not entitled to judgment as a matter of law.
To preclude the entry of summary judgment in favor of Township, Claimants had to allege facts sufficient to show Township’s liability to Claimants for the injuries resulting from the February 3, 1984 motor vehicle accident in Ross Township. 42 Pa.C.S. §§ 8541-8542. Specifically, through the parties’ pleadings, depositions, answers to interrogatories, admissions on file and supporting affidavits, see Pa. R.C.P. No. 1035(a), Claimants had to show (1) that they had a cause of action in negligence against Township, 42 Pa.C.S. § 8542(a), and (2) that Township’s negligent acts fell within the exception to governmental liability listed at 42 Pa.C.S. § 8542(b)(4).
II. Negligence
Claimants assert that, in conformity with 42 Pa.C.S. § 8542(a)(1), either a statutory or a common-law cause of action in negligence against Township was created (1) by Township’s failure to place any traffic-control devices on Route 118, (2) by Township’s alleged inadequate placement of traffic-control devices on Route 118, or (3) by Township’s alleged failure to use police officers to regulate traffic on Route 118 by means other than traffic-control devices. The elements of a cause of action in negligence are a statutory or common-law duty requiring the actor to conform to a certain standard of conduct, the actor’s breach of the duty by failing to conform to the mandated standard of conduct, and an injury (actual loss or damage) to another’s interests proximately caused by the actor’s breach of duty. Morena v. South Hills Health System, 501 Pa. 634, 462 A.2d 680 (1983); Farber v. Engle, 106 Pa.Commonwealth Ct. 173, 525 A.2d 864 (1987).
[269]*269A. Statutory Duty
Under sections 6109 and 6122 of the Vehicle Code, 75 Pa.C.S. §§ 6109 and 6122, a township is authorized to regulate traffic on state-designated highways within its physical boundaries by means of official traffic-control devices or police officers. However, sections 6109 and 6122 do not impose an affirmative statutory duty on a township to regulate traffic on a state-designated highway. Mindala v. American Motors Corp., 518 Pa. 350, 543 A.2d 520 (1988) (no absolute duty to act is created by section 6109); Bruce v. Department of Transportation, 138 Pa.Commonwealth Ct. 187, 588 A.2d 974 (1991) (section 6122 is discretionary); Bendas v. Township of White Deer, 131 Pa.Commonwealth Ct. 138, 569 A.2d 1000 (1990) (section 6122 is not obligatory); Buffalini v. Shrader, 112 Pa.Commonwealth Ct. 228, 535 A.2d 684 (1987) (section 6109 is permissive).
Consequently, in the present case, Township did not owe a statutory duty to Claimants to regulate traffic on Route 118 either by erecting official traffic-control devices on Route 1183 or by using police officers to direct traffic on Route 118.
B. Common-Law Duty
Claimants argue that, given the dangerous condition of Route 118 on February 3, 1984, Township had a common-law duty to regulate traffic on Route 118 through the proper use of traffic-control devices or police officers.
1. Traffic-Control Devices
Pennsylvania’s appellate courts have repeatedly denied the existence of a common-law duty on the part of a township or other local government body to erect official traffic-control devices. Bendas; Farber; see Mindala.
[270]*270Nevertheless, it is well settled that, if a township or other local government body exercises its discretionary authority under sections 6109 and 6122 to erect an official traffic-control device, the township or other local government body then has a common-law duty to utilize and maintain the device properly. Bendas; Farber.
Claimants assert that, on February 3, 1984, Township erected official traffic-control devices on Route 118 by putting flares on the highway to warn approaching motorists of dangerous highway conditions and that, in so doing, Township acted negligently by inappropriately positioning the flares. Claimants do not offer any support for their assertion that flares constitute official traffic-control devices, and our research has not disclosed any.
The phrase “official traffic-control devices” is defined in section 102 of the Vehicle Code, 75 Pa.C.S. § 102, and in the PennDOT regulation at 67 Pa.Code § 211.1 as “[s]igns, signals, markings and devices not inconsistent with this title [i.e., the Vehicle Code which is Title 75 of Pennsylvania Consolidated Statutes] placed or erected by authority of a public body or official having jurisdiction, for the purpose of regulating, warning or guiding traffic.” Flares are not explicitly discussed in any of the statutory or regulatory provisions concerning official traffic-control devices.
The PennDOT regulations at 67 Pa.Code §§ 211.21-32 define the word “signs” by stating the dimension, lettering, construction material, message content, symbol design, and placement requirements for traffic signs and by listing several, different, permissible types of traffic signs such as speed limit signs, stop signs, and truck weight limit signs. The regulation at 67 Pa.Code § 211.27 details the acceptable kinds of illumination that may be used to make the message or symbol on a traffic sign more visible. It is apparent from the PennDOT regulations that flares constitute neither traffic signs nor acceptable forms of illumination which may accompany traffic signs.
[271]*271The word “signals” is defined in the PennDOT regulation at 67 Pa.Code § 211.1 to encompass “[a]ny power-operated traffic control device, except a sign, barricade warning light, flashing arrow board, or steady bum electric lamps, by which traffic is warned or is directed to take some specific action.” Because traffic signals are power-operated traffic-control devices, flares cannot qualify as traffic signals.
The phrase “traffic control signal” is separately defined in the PennDOT regulation at 67 Pa.Code § 211.1 as a “device, whether manually, electrically, or mechanically operated, by which traffic is alternately directed to stop and permitted to proceed.” Inasmuch as flares do not alternately stop and permit the flow of traffic, flares are not traffic control signals.
The word “markings” is defined in the PennDOT regulation at 67 Pa.Code § 211.1 as “[a]ll lines, patterns, words, colors, or other devices, except signs and power operated traffic control devices, set into the surface of, applied upon, or attached to the pavement or curbing or to objects within or adjacent to the roadway.” Pavement and curb markings include such items as center-line and two-lane street markings, pedestrian crosswalk markings, parking space markings, and highway exit ramp markings. 67 Pa.Code §§ 203.71-.72 and 211.1131-.1214. The PennDOT regulation at 67 Pa.Code § 211.1135 mandates that pavement markings be yellow, white or red in color and further states that black may be used in combination with the three specified colors for contrast to increase the visibility of the markings. Indisputably, flares cannot be deemed “markings.”
Flares are expressly described in the PennDOT regulations at 67 Pa.Code §§ 167.3-.5 and .8 as liquid-burning, warning devices which must be carried as emergency equipment on certain types of vehicles to alert oncoming motorists to dangers posed by the stopping or disabling of these vehicles on a roadway or road shoulder.
[272]*272The differences between the aforementioned statutory and regulatory provisions governing official traffic-control devices and the regulatory provisions exclusively governing flares further indicate that flares are not official traffic-control devices. Whereas official traffic-control devices must be “placed or erected by authority of a public body or official having jurisdiction,” 75 Pa.C.S. § 102; 67 Pa.Code § 211.1, flares are to be positioned on a roadway by the driver of a stopped or disabled vehicle. 67 Pa.Code § 167.8. Moreover, section 6122 of the Vehicle Code states that, generally, a township must obtain approval from PennDOT before erecting an official traffic-control device on a state-designated highway whereas the regulation at 67 Pa.Code § 167.8 does not require a vehicle driver to receive approval from PennDOT or any other authority before placing flares on a roadway. In fact, the regulation at 67 Pa.Code § 167.8 does not allow any opportunity for a driver to secure approval before using flares because the regulation mandates that a driver place flares or other sanctioned emergency warning devices on a roadway “as soon as possible, but in any event within 10 minutes” after the driver’s vehicle becomes stopped or disabled upon the roadway.
Additional guidance in interpreting the expression “official traffic-control devices” is provided by subsection 3111(a) of the Vehicle Code, 75 Pa.C.S. § 3111(a), which requires the driver of any non-emergency vehicle to “obey the instructions of any applicable official traffic-control device” unless otherwise directed by a uniformed police officer or other appropriate official. Citing subsection 3111(a), we held in Garrett that a bus stop did not qualify as an official traffic-control device because “[o]ne cannot ‘obey the instructions of’ a bus stop.” Id., 127 Pa.Commonwealth Ct. at 497, 562 A.2d at 391. Similarly, one cannot obey the instructions of a flare inasmuch as a flare does not specify any particular action which a driver must perform.
Given the distinct statutory and regulatory provisions concerning the definitions and uses of official traffic-control devices and flares, we are compelled to conclude that flares [273]*273are not official traffic-control devices. The Township cannot be charged with a common-law duty to utilize and maintain properly an instrumentality which we conclude is not an official traffic-control device. Therefore, we must also hold that Claimants have not established a cause of action in negligence against Township based on Township’s February 3, 1984 placement of flares on Route 118.
2. Police Regulation of Traffic
Next, we consider whether, on February 3, 1984, Township had a common-law duty to regulate traffic on Route 118 by the reasonable use of police officers and the reasonable means at the officers’ disposal. We deem the Pennsylvania supreme court’s analysis in Mindala to be dispositive in this regard.
In Mindala, several motorists were involved in an automobile accident at the intersection of two state-designated highways in a township in Lancaster County. On the day of the accident, a stop sign was missing from the intersection. The stop sign had been erected by the Commonwealth. Twenty-four hours prior to the accident, the township police had been informed that the stop sign was missing from the intersection. The township police travelled to the intersection to verify that the stop sign was missing. The township police did nothing to alert motorists to the potential danger at the intersection caused by the missing stop sign.
The supreme court acknowledged that under the Vehicle Code, the township did not owe a statutory duty to the motorists involved in the accident. Nevertheless, “[b]alancing the motorists’ need for protection with the resulting burden imposed upon the [t]ownship police,” the supreme court concluded that the township did have a common-law duty to protect the motorists. Id., 518 Pa. at 362, 543 A.2d at 526.
The supreme court reasoned that “[s]ince the township police possessed statutory authority to regulate traffic [pursuant to the Vehicle Code], had knowledge of a dangerous situation [i.e., 24 hours’ advance notice that a stop sign was [274]*274missing from the highway intersection], and the capability to rectify the problem [by using a portable stop sign which the police possessed, by activating warning devices on a police patrol car, by having township police officers direct traffic, by summoning help from the nearby state police barracks], a [common-law] duty was created to reasonably exercise that authority and the failure to do so violated that duty.” Id., 518 Pa. at 363, 543 A.2d at 527; accord Socarras v. City of Philadelphia, 123 Pa.Commonwealth Ct. 197, 552 A.2d 1171, petition for allowance of appeal denied, 522 Pa. 608, 562 A.2d 829, and petition for allowance of appeal denied sub nom. Petition of City of Philadelphia, 522 Pa. 605, 562 A.2d 828 (1989).
Observing the similarity between the facts in Mindala and the factual allegations in the present case, we conclude that Claimants have averred sufficient facts to show that, on February 3, 1984, Township owed a common-law duty of care to Claimants to regulate traffic on Route 118 through the reasonable use of police officers and the reasonable means at their disposal. Like the police in Mindala, Township police had statutory authority under the Vehicle Code to regulate traffic on the state-designated highway in question (here, Route 118 within Township’s boundaries). Like the police in Mindala, Township police had knowledge of dangerous conditions on the state-designated highway in question (here, the dangerous conditions of Route 118 caused by the icy roadway surface and the presence of automobiles involved in an earlier accident on Route 118).4 Like the police in Mindala, Township police were capable of correcting or reducing the problem on [275]*275Route 118 with a minimal use of manpower and resources (here, flares, warning lights on police patrol cars, warning lights on other emergency vehicles at the accident scene).
In Mindala, the Pennsylvania supreme court held that a reasonable exercise of a township’s authority to use police officers to regulate traffic pursuant to 75 Pa.C.S. § 6109 would fulfill the common-law duty of a township to protect motorists from a known dangerous highway condition, i.e., the lack of a stop sign where two state-designated highways intersected in the township’s physical boundaries. The supreme court listed several examples of acts that, under the facts of Mindala, would have qualified as a reasonable exercise of the township’s authority to regulate traffic in order to protect motorists from the known highway danger: the utilization of the township’s portable stop sign, the activation of warning devices on a police patrol car positioned at the intersection, the dispatching of township police officers to direct traffic at the intersection, the summoning of help from the nearby state police barracks. Inasmuch as the township police in Mindala did not attempt any corrective measures to protect motorists from the known highway danger, the supreme court held that the township police in Mindala had breached their common-law duty to regulate traffic by the use of police officers. Accord Socarras.
Regarding Township’s fulfillment or breach of its common-law duty to Claimants on February 3, 1984, the following scenario in the present case is pertinent. At approximately 9:00 p.m. on February 3, 1984, Route 118 in Township’s boundaries was the scene of an accident that did not involve Claimants (the earlier accident). R. 127a-131a, 149-152a. At approximately 10:05 p.m. on February 3, Township police were notified of the earlier accident’s occurrence. R. 30a. By approximately 10:15 p.m., Township police arrived at the scene of the earlier accident. R. 64a. To warn approaching motorists of danger on Route 118, Township police placed flares along Route 118 on either side of the earlier accident scene, R. 42a-45a and 65a, and used the [276]*276flashing emergency lights on their patrol car to warn approaching motorists of danger. R. 41a. Additionally, other emergency vehicles (two ambulances, two fire police vehicles, and a tow truck) at the earlier accident scene operated their flashing emergency lights. R. 38a-41a. Two flood lights mounted on telescoping poles and tripods were also used to illuminate the scene of the earlier accident. R. 51a. At 11:45 p.m., Claimants’ accident occurred at the scene of the earlier accident on Route 118. R. 36a.
Comparing the facts in Mindala with the factual allegations in the present case, we conclude that Claimants have not established that Township breached its common-law duty to Claimants to regulate traffic on Route 118 on February 3, 1984, by the use of police officers and the reasonable means at their disposal. The significant difference between Mindala and the present case is that, whereas the police in Mindala had 24 hours’ advance notice of a dangerous highway condition and failed to take any remedial measures to protect motorists, Township police had merely one hour and 40 minutes’ advance notice5 of the dangerous Route 118 conditions and took several remedial measures to protect motorists.
Given the very limited (one hour and 40 minutes) notice which Township police had of the dangerous condition of Route 118 on February 3, 1984, Township’s use of flares and flashing emergency lights on police and other emergency vehicles constituted a reasonable exercise of Township’s authority to regulate traffic in order to protect motorists from the known highway danger and thus fulfilled Township’s common-law duty to Claimants. For this reason, we further hold that Township was entitled to summary judgment as a matter of law under 42 Pa.C.S. § 8542(a)(1) inasmuch as Claimants failed to make sufficient factual averments to establish Township’s negligence in regulating [277]*277traffic on Route 118 by the use of police and the reasonable means at their disposal.6
Because Claimants’ factual allegations have been insufficient to establish any cause of action in negligence against Township, liability cannot be imposed on Township under the governmental immunity exception at 42 Pa.C.S. § 8542(b)(4). Mindala; 42 Pa.C.S. § 8542(a).
III. Leave to Amend Complaint
Claimants maintain that the trial court abused its discretion by refusing to grant them leave to amend their complaint in order to “specifically allege a ‘dangerous condition of traffic controls’ if such language was essential to set forth a cause of action against Ross Township Police Department.” Claimants’ Appellate Brief at 22; Claimants’ Motion for Trial Court Reconsideration, para. 7, at R. 182a.
Relying on Connor v. Allegheny General Hospital, 501 Pa. 306, 461 A.2d 600 (1983), Claimants assert that, when a party is merely attempting to amplify allegations contained in its original pleadings, amendment of a complaint should be liberally allowed so that the party may fully develop its theories. Accord Bendas.
Because we have held that Township lacked a duty to erect traffic-control devices on state-designated highway Route 118 and that Township’s February 3, 1984 use of flares on Route 118 did not constitute an erection of traffic-control devices on Route 118, it is obvious that the proposed amendment of Claimants’ complaint would not state a cause of action in negligence against Township. Garrett. Consequently, we conclude that the trial court did not abuse its discretion by denying Claimants leave to amend their complaint. See Connor.
Accordingly, because we have determined that the trial court properly entered summary judgment in favor of [278]*278Township, we affirm the trial court’s order of September 25, 1990.
ORDER
AND NOW, April 13, 1992, the September 25, 1990 order of the Court of Common Pleas of Luzerne County in the above-captioned matter is hereby affirmed.
