Evidence After a Car Crash: Police Reports and Dashcam Video
Evidence from a car crash starts to disappear within hours. Vehicles get towed and repaired, video gets recorded over and witnesses become harder to find. A car accident lawyer typically starts with the police report and any photos or video, then the data stored in the vehicles. Here is how each source fits into a claim.
The police report
When officers respond to a crash, they usually prepare a crash report, sometimes called a police report. It typically lists the drivers and vehicles involved, with insurance details for each, along with a diagram, a short narrative and any citations issued. Many states also require drivers to report crashes that involve injury, death or property damage above a set amount. Copies are usually available from the agency that responded, such as a https://archerxyuc692.lumenforgex.com/posts/rear-end-and-t-bone-collisions-fault-injuries-and-evidence city police department, a sheriff's office or the state highway patrol, sometimes for a fee.
Insurers rely heavily on the crash report, but it is not the final word on fault. States differ on whether an officer's opinions can be used at trial. If the report contains a factual error, such as a wrong plate number, the agency may accept a request for a correction or a supplement. An auto accident attorney will compare the report with the photos and statements.
Video and photo evidence
Dashcam video can show the moments before a crash better than a witness can. Keep the original file with its timestamp, instead of a phone recording of the screen, and store a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, though many systems record over footage within days or weeks. Photos taken at the scene show vehicle positions, debris, skid marks and road signs, while photos of injuries taken over several weeks can document healing.
The car's own black box
Many cars and light trucks carry an event data recorder (EDR). NHTSA describes an EDR as a device that records technical vehicle and occupant information for a brief period, seconds rather than minutes, around the time of a crash. Depending on the vehicle, the data may include speed and brake application as well as seat belt use. NHTSA's rule in 49 CFR Part 563 sets requirements for EDRs in light vehicles that have them. Under the Driver Privacy Act of 2015, EDR data generally belongs to the vehicle owner or lessee, and others may access it only in limited situations, such as with the owner's consent or a court order.
EDR data can be lost if the car is repaired or crushed. Insurers often move a total loss vehicle to a salvage auction quickly, so a car accident attorney may send a preservation letter asking that the vehicle be held until the data is downloaded.
Witness statements and medical records
Independent witnesses carry weight because they have no stake in the claim. Their names and phone numbers should be collected at the scene if it is safe to do so. Medical records link the injuries to the crash, and insurers often point to gaps in treatment to dispute a claim. Keeping the claim number in one place, with a log of each call to the adjuster, makes later questions easier to answer. A short journal of pain levels and missed work, written while the details are fresh, can also help. This article is general information, not legal advice, and no result can be predicted from it.
