Proving a bicycle accident claim in Pennsylvania requires three things: evidence that the driver was negligent, evidence that their negligence caused the crash, and documentation of your damages.
Under Pennsylvania’s modified comparative negligence rule, which means your compensation is reduced by your percentage of fault, strong evidence is what keeps blame off you and money in your pocket.
The core categories of evidence in a Pennsylvania bicycle accident claim include:
- Physical evidence: Your damaged bicycle, helmet, torn clothing, and broken gear from the crash
- Photographic and video evidence: Scene photos, dashcam footage, traffic camera recordings, and business surveillance video
- Documentary evidence: The police report, traffic citations issued to the driver, and your medical records and bills
- Testimonial evidence: Eyewitness statements, 911 call recordings, and expert witness testimony
- Digital evidence: GPS data from cycling apps, the driver’s cell phone records, and vehicle black box data
- Financial evidence: Pay stubs, tax returns, and employer letters documenting your lost income
What Should You Do Right After the Crash to Protect Evidence?
The hours and days right after a bicycle accident are when the most important evidence is either preserved or lost for good. Taking the right steps protects both your health and your legal rights.
Get medical care immediately. Adrenaline can mask serious injuries like concussions or internal bleeding, and a gap in treatment gives insurers grounds to argue your injuries weren’t caused by the crash. Getting checked out right away creates an official medical record that ties your injuries directly to the accident.
Call the police and get a report. Pennsylvania law requires you to report any accident involving injury. State the facts clearly to the responding officer, but do not apologize or accept blame. Request a copy of the police report, it will be one of the first things an insurance company asks for.
Photograph everything you can. Use your phone to capture the positions of the car and your bike, license plates, skid marks, road debris, traffic signals, bike lane markings, and your visible injuries. Take wide shots and close-ups, both matter.
Preserve your bike, helmet, and clothing. Do not repair your bicycle, wash your clothes, or throw anything away. Your damaged gear can help an expert reconstruct the crash, show the angle of impact, and support your injury claim.
What Bike-Specific Evidence Can Strengthen Your Case?
Certain types of evidence are unique to bicycle accident claims and can be the difference between a denied claim and a full recovery.
How to Secure Traffic and Dashcam Footage Fast
Surveillance footage can be overwritten quickly, so you should act promptly to request its preservation. You need to act fast to identify nearby cameras at businesses, traffic lights, or residences and send a formal written preservation request.
This is called a “spoliation letter,” and it legally obligates the holder to save the footage. Our Pennsylvania bicycle accident attorneys send these letters immediately when retained, before the footage disappears.
Can Strava or Garmin Data Help Prove Your Claim?
Yes. GPS data from apps like Strava or Garmin provides an objective, time-stamped record of your ride. It can confirm your speed, your route, and your exact location at the moment of impact, proving you were riding lawfully and where you had every right to be.
Can Black Box Data or Phone Records Prove the Driver’s Fault?
Modern vehicles are equipped with an Event Data Recorder (EDR), a “black box” that records speed, braking, and steering input in the seconds before a crash. This data can prove the driver was speeding or never braked. Cell phone records can prove distracted driving.
Both typically require a subpoena to access, which is one of the most important reasons to have an attorney on your side early.
How Do Witnesses and 911 Calls Help?
Independent witnesses—people who have no stake in the outcome—carry significant weight with insurance companies and juries. If you can, collect names and phone numbers from anyone who saw the crash.
Additionally, 911 recordings can capture a driver’s unfiltered, spontaneous statements about what happened, which are often admissible as evidence.
What Pennsylvania Bike Laws Affect Fault and Evidence?
Knowing the specific traffic laws that apply to cyclists in Pennsylvania shapes which evidence matters most in your claim.
Pennsylvania’s Four-Foot Passing Law requires drivers to give cyclists at least four feet of clearance when passing. Evidence like dashcam footage, witness statements, and photos of vehicle position can prove a driver violated this rule.
Pennsylvania’s dooring law prohibits anyone from opening a car door into the path of an oncoming cyclist. If you were hit by a car door, photos of the door’s position and witness accounts can establish the driver’s liability.
Lighting requirements at night require a white front lamp and a red rear reflector when riding between sunset and sunrise. If you were hit at night without proper lighting, the insurance company will use this to shift blame onto you.
It does not automatically disqualify your claim, but it is a factor that must be addressed with other strong evidence.
How Does Comparative Negligence Affect Your Bicycle Claim?
Pennsylvania’s modified comparative negligence rule means you can still recover compensation as long as you are 50% or less at fault for the accident. Your final payout is reduced by your percentage of fault — and if you are found 51% or more at fault, you recover nothing.
Here is how fault percentages affect a $100,000 claim:
| Your Assigned Fault | Total Damages | Your Recovery |
| 0% | $100,000 | $100,000 |
| 20% | $100,000 | $80,000 |
| 50% | $100,000 | $50,000 |
| 51% or more | $100,000 | $0 |
Strong evidence is your best tool for keeping your fault percentage as low as possible. A single piece of video showing the driver ran a stop sign can shift the blame entirely onto them and protect your full recovery.
What Medical Evidence Do You Need for Your Injuries and Damages?
Medical evidence does two things in a bicycle accident claim: it proves your injuries are real, and it quantifies what those injuries cost you.
How to Document a Concussion or Traumatic Brain Injury
A Traumatic Brain Injury (TBI) occurs when a blow or jolt to the head disrupts normal brain function, one of the most common and serious injuries in bicycle accidents. Documenting a TBI requires more than just an emergency room visit.
You will need imaging results like CT scans or MRIs, reports from neuropsychological evaluations, and a written symptom journal documenting headaches, memory problems, and difficulty concentrating.
How to Prove Lost Wages and Future Care Costs
To recover compensation for your financial losses, you need clear documentation. This includes:
- Pay stubs and W-2s showing your income before the accident
- An employer letter confirming the days you missed and any lost opportunities
- A life care plan from a medical expert projecting the cost of future treatment and rehabilitation
- Vocational expert testimony quantifying how your injuries affect your ability to earn income in the future
What Tactics Do Insurers Use to Undermine Bicycle Claims?
Insurance companies are not on your side. Their adjusters start building a case against you immediately, and you need to know what they are looking for.
- Recorded statements: Adjusters may call and ask for a recorded statement, hoping you will say something that assigns blame to you. Never give a recorded statement without an attorney present.
- Social media activity: Investigators will look at your social media accounts for photos or posts they can use to argue your injuries are not as serious as you claim.
- Independent Medical Exams (IMEs): The insurer may send you to a doctor they hired. These doctors frequently produce reports that minimize your injuries.
- Gaps in treatment: Any missed appointment or delay in seeking care will be used to argue you were not truly hurt or that your injuries came from somewhere else.
Do Not Wait! Your Evidence Has a Deadline
After a bicycle accident, time works against you. Surveillance footage is erased, witnesses move on, and physical evidence at the scene disappears. Under Pennsylvania law, you have two years from the date of the crash to file a personal injury lawsuit.
If a government entity is responsible—for example, because a road was dangerously maintained—you may have as little as six months to file a formal notice of your claim.

Frequently Asked Questions
What If I Don’t Have Photos and the Police Report Is Inaccurate?
Even without photos and with an inaccurate police report, we can still build your case using accident reconstruction experts, witness statements, and surveillance footage, and we can formally challenge errors in the police report through a written supplemental request.
Does Not Wearing a Helmet Reduce Your Compensation in Pennsylvania?
Pennsylvania only requires helmets for cyclists under 12, so not wearing one as an adult does not legally bar your claim, but the insurance company will likely argue it contributed to your head injuries to reduce their payout.
How Do You Formally Request Business or Traffic Camera Footage?
You or your attorney must send a written preservation letter to the business or government agency that owns the camera, which legally obligates them to retain the footage before it is automatically overwritten, often within days of the crash.
Do Claims Against a Government Entity for a Road Defect Have a Shorter Deadline?
Claims against PennDOT or a local municipality require written notice of your intent to sue within six months of the accident, which is far shorter than the standard two-year statute of limitations.
Can GPS and Fitness App Data Be Used as Evidence in Pennsylvania?
Yes, GPS data from apps like Strava or Garmin is admissible in Pennsylvania and is regularly used to provide an objective record of your speed, route, and the exact time and location of the collision.
