What Evidence Should I Collect After a Car Accident?
The evidence you gather at the scene — and in the days that follow — can make or break your injury claim. Here's a complete evidence checklist for accident victims.
Evidence Is the Foundation of Every Injury Claim
In personal injury law, the burden of proof rests with the injured party. You must demonstrate that the other party was at fault, that you were injured, and that your injuries caused your damages. Every piece of evidence you collect strengthens your ability to meet that burden.
Scene Evidence (Collect Immediately)
Photographs and Video
Your smartphone camera is one of your most valuable tools. Photograph everything from multiple angles: all vehicles and their positions, visible damage to each vehicle, skid marks and road debris, traffic signals and signs, weather and road conditions, your own injuries, and the broader accident scene.
Driver and Witness Information
Collect the full name, address, phone number, driver's license number, license plate, and insurance information from every driver involved. Gather the same contact information from any witnesses — their accounts are invaluable if liability is disputed later.
The Police Report
If law enforcement responds to the scene, get the report number. Request the full written report from your local police department once it's available. The report documents the officer's observations and any citations issued.
Medical Evidence (Gather Promptly)
Emergency Room and Urgent Care Records
Every medical visit related to your accident should be documented. Request copies of all records — intake notes, diagnoses, imaging results (X-ray, MRI, CT), treatment plans, and discharge summaries.
Follow-Up Treatment Records
Records from your primary care physician, specialists, physical therapists, chiropractors, and mental health providers all support your claim. Ask each provider to document how your injuries affect your daily functioning.
Prescription Records and Medical Bills
Keep all bills, explanations of benefits from your health insurer, and prescription receipts. These document your economic damages.
Financial Evidence
Pay Stubs and Employer Documentation
If your injuries caused you to miss work, document your lost wages. This typically requires pay stubs from before the accident and a letter from your employer confirming the dates and hours missed.
Repair Estimates and Receipts
Get multiple repair estimates for your vehicle. Keep all receipts for rental cars, towing, and other out-of-pocket costs related to the accident.
Ongoing Evidence (Preserve Throughout Your Case)
A Pain and Symptom Journal
Starting immediately after the accident, keep a daily journal documenting your pain levels, symptoms, and how your injuries affect your life. Record activities you cannot perform, sleep disruptions, emotional struggles, and the impact on your relationships. This contemporaneous record carries significant weight in negotiations and litigation.
Communications with Insurance Companies
Keep records of all calls (note the date, time, and what was discussed), emails, and letters to and from any insurance company involved in your claim.
Social Media and Digital Communications
Be careful what you post online. Insurance companies monitor social media. Avoid posting anything that could be used to contradict your claimed injuries or activities.
Black Box and Digital Evidence
Modern vehicles often contain event data recorders (EDRs, or 'black boxes') that record speed, braking, and other data in the seconds before a collision. This evidence is often critical in disputed liability cases, particularly in truck accidents. An attorney can send a preservation letter to prevent this data from being overwritten or destroyed.
Surveillance and Traffic Camera Footage
Nearby businesses, traffic cameras, and dashcams may have captured the accident. This footage is often overwritten within days. Acting quickly — or having an attorney send a preservation demand — can secure this critical evidence.
Frequently Asked Questions
What if I forgot to take pictures at the scene?
Return to the scene as soon as possible to photograph road conditions and the location. Request the police report, contact witnesses, and focus on gathering strong medical documentation of your injuries.
How long should I keep accident evidence?
Retain all evidence until your case is fully resolved — through settlement or final judgment. For serious injuries, that can mean years. Store digital copies in a secure cloud location as a backup.
