Bicycle Accident Fault in Pennsylvania: The Statute the Defense Still Gets Wrong

Bicycle Accident Fault in Pennsylvania: The Statute the Defense Still Gets Wrong

Open enough Pennsylvania bicycle files and the same citation keeps turning up in the answer, the expert report and the mediation statement: 75 Pa.C.S. § 3505, offered for the proposition that the cyclist had to ride as far right as practicable and failed to.

Pull the section. It does not say that, and it has not said that since Act 3 of 2012. The rule moved, and bicycle accident lawyers still working from the pre-2012 text concede a duty their client never owed.

What section 3505 covers now

Five things, none of them a far-right duty:

•        A general instruction to obey the rules of the road

•        Permission to ride the shoulder, in the same direction as traffic

•        A cross-reference for riders moving slower than prevailing speed

•        Permission to ride near the left curb on a one-way roadway with two or more marked lanes

•        A limit of two abreast

The positioning rule moved to § 3301(c). Paragraph (1) requires a pedalcycle travelling below the normal speed of traffic to keep to the right-hand lane then available, or as close as practicable to the right-hand curb or edge. Overtaking and preparing a left turn are carved out on the face of it.

Paragraph (2) then switches the rule off in two situations:

•        A pedalcycle using any portion of an available roadway due to unsafe surface conditions

•        A pedalcycle using a roadway no wider than one lane of traffic in each direction

That second one does most of the work. On an ordinary two-lane road, one lane each way, the positioning duty does not apply at all, and those are the roads where a large share of serious collisions happen. Section 3505(c) adds a further qualifier for riders below prevailing speed: the § 3301 rules govern unless it is unsafe to follow them.

None of this needs an expert to explain. It needs a deposition question, and where a report rests on the repealed version, a motion in limine.

Why lane position decides the right hook

Under § 3331(e), no turn by the driver of a motor vehicle shall interfere with a pedalcycle proceeding straight while operating in accordance with Chapter 35.

The condition at the end is where the defense will spend its time. Protection attaches to a cyclist operating in accordance with Chapter 35, so the fight becomes lighting, riding two abreast, entry from a sidewalk, and lane position. Showing that the § 3301(c) duty never attached removes the largest of those.

Section 3331(a) belongs in the same breath. A driver intending to turn right must approach and make the turn as close as practicable to the right-hand curb or edge. That is frequently inconsistent with the arc the driver took across the cyclist.

Passing distance and the centerline

Under § 3303(a)(3), the driver of a motor vehicle overtaking a pedalcycle in the same direction must pass to the left within not less than four feet, at a careful and prudent reduced speed. The duty falls on the driver of a motor vehicle, so a cyclist overtaking another cyclist sits outside it.

Under § 3307(b.1) it is then permissible to pass a pedalcycle in a marked no-passing zone, but only if done in accordance with §§ 3303(a)(3) and 3305. The centerline permission is conditional. A driver who crossed the line and still left two feet of clearance has not satisfied it, and the shorthand that a driver may simply cross to pass a cyclist drops the condition that matters.

Left turns need less work. A driver turning left within an intersection, or into an alley, private road or driveway, must yield to any vehicle approaching from the opposite direction which is so close as to constitute a hazard. That is § 3322. A pedalcycle is a vehicle under § 102, though not a motor vehicle, and § 3501(a) gives a rider on a roadway the rights and duties of a driver. The duty applies by definition, with no analogy required.

Lighting is the provision that runs the other way

Between sunset and sunrise, § 3507(a) requires:

•        A front lamp emitting a white beam visible at least 500 feet to the front

•        A red reflector facing rearward, visible at least 500 feet

•        An amber reflector on each side

Flashing white and red devices are permitted as supplements. Note that the rear requirement is a reflector, not a lamp, which is worth confirming against the text before a deposition where the point will be contested.

There is also no civil-evidence provision anywhere in § 3507. Unlike the helmet statute, nothing in it limits use of non-compliance at trial, and defense counsel argue unlit riding as comparative negligence as a matter of routine. Whether a violation amounts to negligence per se, or only evidence of negligence, does not appear to have been squarely resolved on appeal. Causation is a separate hurdle in any event, and a missing rear reflector has little to say about a left-cross collision at two in the afternoon.

Watch the framing on darkness too. Nationally, more pedalcyclist fatalities occurred in the dark, 52 percent, than in daylight, 44 percent, in 2024. PennDOT reports the opposite pattern for crashes in Pennsylvania, stating that bicycle crashes here mainly occur during daylight hours, in contrast to pedestrian crashes. Fatalities and crashes are different populations, and conceding the darker one by accident gives away a fact that is not in evidence.

How far the helmet provision reaches

Section 3510(a) requires a helmet only for riders under 12. Subsection (c) is the interesting one, because it is drafted in two registers.

Its first two clauses bar evidence of a violation or alleged violation of subsection (a), and bar instructing a jury that conduct constituted such a violation. Both are tied to the under-12 mandate. The last two clauses are not. They provide that failure to use a pedalcycle helmet shall not be considered as contributory negligence, and shall not be admissible as evidence in the trial of any civil action. No age qualifier appears, and no cross-reference back to subsection (a).

On the face of the statute, then, the contributory negligence bar and the admissibility bar are general, and they reach adult riders. That is the better reading of the text. No Pennsylvania appellate court appears to have squarely decided it, so brief it as a question of first impression. Expect the opposing brief to argue that the subsection must be read as a whole.

The fifty percent line, and who pays after it

Title 42 bars recovery, at § 7102(a), only where the plaintiff’s negligence was greater than the causal negligence of the defendants against whom recovery is sought, with damages diminished in proportion. Elder v. Orluck, 511 Pa. 402, 515 A.2d 517 (1986), confirms the comparison runs against the combined negligence of all defendants, not defendant by defendant. A plaintiff at exactly 50 percent recovers, reduced by half.

The Fair Share Act at § 7102(a.1) then makes each defendant severally liable, with exceptions. In a case against a driver and a municipality, the exception that matters most is § 7102(a.1)(3)(iii). Liability is joint and several where a defendant has been held liable for not less than 60 percent of the total apportioned to all parties. Below that line, an apportioned verdict against a thinly insured driver collects like an apportioned verdict.

Where cyclists sit better than motorcyclists

This is the part clients and referring lawyers most often have backwards, because the motorcycle rule is better known.

Section 1714 of Title 75 makes an operator or occupant of a recreational vehicle not intended for highway use, motorcycle, motor-driven cycle, motorized pedalcycle or like type vehicle required to be registered ineligible to recover first-party benefits. A bicycle is none of those. It is propelled solely by human power, which puts it outside the § 102 definition of a motor vehicle, and it requires no registration. The injured cyclist is not an ineligible claimant.

Recovery then follows the order of priority in § 1713(a), of which the first, second and fourth paragraphs can reach a cyclist:

•        (1) For a named insured, the policy on which he is the named insured

•        (2) For an insured, the policy covering the insured

•        (4) For a person who is not the occupant of a motor vehicle, the policy on any motor vehicle involved in the accident

Paragraph (3) covers occupants of an insured motor vehicle and has no application here. The practical result is that a cyclist carrying no policy of their own can still reach the striking vehicle’s first-party medical benefit, which § 1711(a) sets at a minimum of $5,000.

Two neighbouring sections shape what that benefit does to the tort case. Section 1720 bars subrogation or reimbursement out of the claimant’s tort recovery for those benefits, and § 1722 bars the claimant from recovering the same benefits again as damages from the tortfeasor. Both were partially repealed by Act 44 of 1993 as to workers’ compensation, and both otherwise stand.

There is a trap in the first clause of § 1714, and it has nothing to do with bicycles. An owner of a currently registered motor vehicle who does not have financial responsibility cannot recover first-party benefits at all. A client who owns an uninsured registered car is an ineligible claimant even when the injury happened on a bicycle. Ask about the garage at intake, not at the coverage fight.

What electric assist changes, and what it does not

Chapter 35 does not change. Since Act 154 of 2014, § 102 defines a pedalcycle as a vehicle propelled solely by human-powered pedals or a pedalcycle with electric assist, so § 3301(c), § 3303(a)(3), § 3307(b.1), § 3331(e), § 3507 and § 3510 reach an e-bike in identical terms. Section 3514 adds one rule of its own: no person under 16 may operate one.

Section 1714 does change, because the reasoning above does not survive the move. An e-bike is not propelled solely by human power, so the § 102 motor vehicle exclusion is not available and the argument has to run on the list instead. A pedalcycle with electric assist is not a motorcycle, not a motor-driven cycle, and not a motorized pedalcycle, which § 102 defines as a motor-driven cycle with operable pedals capped at 1.5 brake horsepower, 50 cubic centimeters and 25 miles per hour. Act 154 left the e-assist pedalcycle with no title, registration or insurance requirement, so it is not a like type vehicle required to be registered under this title either. The claimant is still eligible, by a narrower route.

Section 1713(a)(4) is the softer spot, since it turns on the claimant not being the occupant of a motor vehicle. No Pennsylvania appellate decision appears to address whether an e-assist rider is one. Where the client is a named insured or an insured under a household policy, plead (a)(1) or (a)(2) and keep (a)(4) as the fallback.

Check the machine against the definition before any of this matters. Over 100 pounds, over 750 watts, or capable of more than 20 miles per hour on motor power alone, and it is not a pedalcycle at all. It is then likely a motor-driven cycle or a motorcycle, which moves the client inside § 1714 rather than outside it, and takes the § 3510(c) helmet bar with it. Get the motor rating off the plate, the manufacturer’s class, and whether the firmware was unlocked, at intake rather than at the coverage fight.

Limited tort, and exclusions with nothing to grip

Whether a limited tort election binds a plaintiff hurt while riding a bicycle has not been settled by a Pennsylvania appellate court. The nearest authority is L.S. v. David Eschbach, Jr., Inc., 583 Pa. 47, 874 A.2d 1150 (2005), holding that the restrictions in § 1705 do not apply to pedestrians injured in motor vehicle accidents, because the section discusses only drivers and passengers of motor vehicles. A cyclist is likewise neither. The reasoning extends on its own terms, which makes it the argument to run, not a holding to plead.

On underinsured motorist coverage, note only that household vehicle and regular use exclusions operate on an insured occupying a vehicle, and a cyclist occupies nothing. The Gallagher line has narrowed considerably since 2019, through Erie Insurance Exchange v. Mione, 289 A.3d 524 (Pa. 2023), and Rush v. Erie Insurance Exchange, 308 A.3d 780 (Pa. 2024), so check the current state of it against the insuring agreement and the definition of insured on the actual form.

Road defect claims, the six-month clock, and the caps

A personal injury action must be commenced within two years under 42 Pa.C.S. § 5524(2). For a claim against a government unit, § 5522(a)(1) requires a written statement within six months of the injury, filed with the unit and, for a Commonwealth agency, with the Attorney General as well. That deadline arrives constantly in bicycle practice, because pavement edges, drain grates, trolley tracks and potholes are ordinary liability theories.

The six-month rule is quoted more harshly than it reads. Under § 5522(a)(2) the court shall excuse failure to comply on a showing of reasonable excuse. For government units other than the Commonwealth, § 5522(a)(3)(iii) adds that failure shall not be a bar where the unit had actual or constructive notice of the incident or condition. Neither escape is a reason to miss the date, and the constructive notice safe harbor does not reach the Commonwealth.

The harder question is which immunity exception the claim fits. A pothole or similar condition created by natural elements falls, as against PennDOT, under 42 Pa.C.S. § 8522(b)(5). That paragraph is expressly carved out of the broader highways exception at (b)(4), and it requires proof of actual written notice given early enough to have allowed protective measures. Against a municipality, § 8542(b)(6)(i) asks only for actual notice, or notice with which the agency could reasonably be charged.

Then check the ceiling before committing to the claim. Damages against the Commonwealth are capped by § 8528 at $250,000 per plaintiff and $1,000,000 in the aggregate. A local agency claim is capped by § 8553 at $500,000 in the aggregate. Section 8553(c)(2) then allows pain and suffering only on death, or on permanent loss of a bodily function, permanent disfigurement or permanent dismemberment where medical and dental expenses exceed $1,500. In a catastrophic injury on a defective road, the cap often decides whether the claim is worth bringing at all.

Road-condition claims in the northeastern counties turn on who maintains the road. Firms that take these cases, those handling Pennsylvania road-defect claims among them, settle the ownership question before the notice letter goes out. Case summaries published by any firm describe particular matters, and results depend on the facts of each case.

Experts, and the data the client is already carrying

Pennsylvania remains a Frye jurisdiction. Pa.R.E. 702(c) requires that the expert’s methodology be generally accepted in the relevant field, the standard entered Pennsylvania law through Grady v. Frito-Lay, Inc., 576 Pa. 546, 839 A.2d 1038 (2003), and the Supreme Court applied it most recently in Walsh v. BASF Corp., 234 A.3d 446 (Pa. 2020).

Retained reconstructionists examine paint and material transfer, rim and fork deformation, and the location and direction of frame damage to form opinions on impact geometry. SAE’s Collision Reconstruction Methodologies series carries a dedicated volume on bicycle reconstruction, Volume 9, which is the reference to put in front of an expert. Those are opinions for a qualified witness, and they do not belong in a brief unsupported.

Ride data is more useful, and more perishable. A Strava or Garmin file supports an opinion about how fast the cyclist was travelling much better than one about where in the lane they rode. Positional error on consumer devices is measured in feet, and so are lane widths. Two places to look before an expert relies on it are SAE Technical Paper 2021-01-0878 on bicycle GPS positional accuracy, and the EVU study on the accuracy of GPS fitness trackers. Offering this data for lane position invites the cross-examination that takes the rest of it down.

Two mechanical points are worth carrying into intake. Garmin’s incident detection sends an alert with a location to emergency contacts. It is not a crash recorder, and the evidentiary value sits in the ordinary activity file, which happens to run through the moment of impact. And Pa.R.E. 902(13) and 902(14), effective January 2020, make certified records generated by an electronic process, and certified data copied from a device, self-authenticating.

Have the client export their own data at intake, as well as sending preservation letters to the platforms, and do not wait on the platforms to answer. Tell the client not to delete activities, not to change privacy settings, and not to trade in the device or the bicycle. Where evidence does go missing, Schroeder v. Commonwealth, Department of Transportation, 551 Pa. 243, 710 A.2d 23 (1998), sets three factors: the fault of the party who altered or destroyed it, the prejudice to the opponent, and whether a lesser sanction will do.

The Pennsylvania numbers

PennDOT’s 2025 Crash Facts and Statistics reports 1,350 bicycle crashes, the highest total in five years, with 28 bicyclist deaths and 1,335 bicyclist injuries. Statewide traffic deaths that year were 1,047, the lowest figure on record. Year-over-year movement in the bicyclist fatality count is noise on a base that small, so the five-year shape is the honest way to cite it.

For national context, 1,103 pedalcyclists were killed in crashes with motor vehicles in 2024, down 6 percent from 1,173 in 2023. That is still well above the 829 killed in 2015, which was the low point of the decade. Injuries moved the other way, with an estimated 52,887 in 2024 against 49,989 the year before.
