Evidence is the foundation of any accident claim. Without it, a valid claim becomes very difficult to prove. The problem is that the most important evidence often disappears quickly — and the other side's lawyers are working from day one.
Evidence at the Scene
The most valuable evidence is often gathered in the minutes and hours immediately after an accident. If you are physically able to do so, collect the following at the scene:
- Photos and video of the scene — All vehicles from every angle, road conditions, skid marks, debris, traffic signals, weather, and visible injuries
- Witness names and contact information — Neutral witnesses who saw the accident are valuable; their accounts carry significant weight because they have no stake in the outcome
- Police report number — The responding officer's report creates an official record of the crash, identifies the parties, and often documents traffic violations or the officer's initial assessment
- Other driver's information — Full legal name, driver's license number, license plate, insurance company and policy number, vehicle make and model
Medical Evidence
In any personal injury claim, medical records are among the most important evidence. They do more than document your injuries — they establish the connection between the accident and your condition.
- Emergency room records — The initial treatment record establishes the timing and nature of your injuries
- All treatment records — Every follow-up visit, specialist appointment, physical therapy session, and procedure
- Doctor's notes linking injuries to the accident — Explicit documentation that your injuries were caused by the accident, not a pre-existing condition
- Bills and receipts — Every cost associated with your treatment, including medication, medical equipment, and transportation to appointments
- Future treatment recommendations — If your doctor recommends ongoing care, those recommendations form the basis for future medical damages
Lost Income Evidence
If your injuries caused you to miss work, you need documentation to support a lost wages claim:
- Pay stubs — Recent pay stubs establishing your regular income before the accident
- Employer letter — Confirmation from your employer of the days missed and your rate of pay
- Tax returns — For self-employed individuals, tax returns establish your typical annual income
Evidence preservation matters most in the first 24-72 hours after an accident.

Other Important Evidence
Beyond the scene and medical records, several other categories of evidence can be critical depending on the type of accident:
- Surveillance footage — From nearby businesses, traffic cameras, and intersection cameras; must be requested quickly before it is overwritten
- Black box data — Commercial vehicles and many newer passenger vehicles have event data recorders that capture speed, braking, and steering data in the seconds before a crash
- Cell phone records — If distracted driving is a factor, cell phone records can establish whether the other driver was texting or calling at the time of impact
- Maintenance records — For commercial vehicles, maintenance logs can reveal whether known mechanical problems were ignored
What Disappears Fast
Some of the most powerful evidence has a very short window before it is gone permanently:
- Surveillance video — Most commercial systems overwrite footage within 24 to 72 hours; a preservation letter must be sent immediately
- Skid marks and debris — Cleared from the road within hours, sometimes by the time law enforcement finishes their investigation
- Witness memories — Details fade quickly; the longer you wait, the less reliable witness accounts become
- Scene conditions — Weather, lighting, and road conditions at the time of the accident cannot be re-created later
