Evidence After a Car Crash: Police Reports and Dashcam Video

How Crash Reports and Dashcam Video Shape an Auto Accident Claim

Evidence from a car crash starts to disappear within hours. Cars are towed and repaired, video is overwritten and witnesses become harder to find. A car accident attorney usually looks first at the police report, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.

The crash report

Officers who respond to a crash usually prepare a crash report, sometimes called a police report. It usually records who was driving each vehicle and which insurer covers it, and it often includes a diagram, a short narrative and any citations. 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 city police department, a sheriff's office or the state highway patrol, often for a small fee.

Insurers rely heavily on the crash report, but it does not decide 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. A car crash attorney will compare the report with the photos and statements.

Photos and dashcam footage

Dashcam footage can capture the seconds before a crash more clearly than any witness. Keep the original file with its timestamp, rather than a phone recording of the screen, and make a backup copy. Traffic cameras and nearby businesses may also have recorded the crash, though many systems record over footage within days or weeks. Photos taken at the scene show vehicle positions, debris, skid marks and road signs, and photos of injuries taken over several weeks can show how they changed.

The event data recorder

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, measured in seconds, not 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 https://kameronkdqn741.talesignal.com/posts/who-is-liable-in-a-car-crash them. Under the Driver Privacy Act of 2015, EDR data generally belongs to the vehicle owner or lessee, and access by others is limited to situations such as owner consent or a court order.

EDR data can be lost when a car is repaired or sold for salvage. Total loss vehicles are often moved to salvage auctions within weeks, so an automobile accident attorney may send a preservation letter asking that the vehicle be held until the data is downloaded.

Witnesses and medical records

Witnesses with no stake in the claim often carry weight. Collect their names and phone numbers at the scene when it is safe. Medical records connect 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. Pain levels, missed work and appointments are worth noting in a journal while the details are fresh.
