How to Prove Fault in a Car Accident
Proving fault is the foundation of any car accident injury claim. Without establishing that the other driver was negligent, you cannot recover compensation. Here is how fault is determined — and how to build the strongest possible case.
Key Evidence for Proving Fault
Police Report
The police report is the most important piece of evidence. It records the officer's assessment of fault, any citations issued, witness statements, and a diagram of the accident scene. Request a copy within 5–7 days.
Photos & Video
Photographs of vehicle damage, road conditions, skid marks, traffic signs, and injuries. Dashcam footage, traffic camera footage, and nearby security camera footage can be decisive.
Witness Statements
Independent witnesses who saw the accident are highly credible. Get their names and contact details at the scene. Your attorney can take formal statements later.
Medical Records
Medical records establish the link between the accident and your injuries. They also show the severity and timeline of your injuries, which directly affects settlement value.
Expert Witnesses
In complex cases, accident reconstruction experts can analyse physical evidence to determine speed, direction of impact, and fault. Medical experts can testify on injury causation.
Traffic Citations
If the other driver was cited for speeding, running a red light, or DUI, this is strong evidence of negligence and can be used in your civil claim.
Comparative Fault Rules by State
