Evidence After a Car Crash: Police Reports and Dashcam Video
By @edwinuvjj741
The evidence in a car crash claim starts to scatter within hours. Cars are towed and repaired, video is overwritten 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. This article explains how each source fits into a claim.
The police report
When officers respond to a crash, they usually prepare a crash report, often 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 city police department, a sheriff's office or the state highway patrol, sometimes for a fee.
A crash report is influential in insurance claims, but it is not the final word on fault. Rules on using an officer's opinions at trial vary by state. When a report has a factual error, such as a wrong plate number, the agency may accept a request to correct or supplement it. 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 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. Traffic cameras and nearby businesses may also have recorded the crash, but many systems overwrite footage within days or weeks. Scene photos can show where the vehicles stopped and the debris and skid marks around them, and photos of injuries taken over several weeks can show how they changed.
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, it may record speed and braking, along with seat belt use. NHTSA's rule in 49 CFR Part 563 sets requirements for EDRs in https://caraccidentlawyers.wiki/reference/georgia-deadlines/ light vehicles that have 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 if the car is repaired or crushed. Insurers often move a total loss vehicle to a salvage auction quickly, so a motor vehicle accident lawyer may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data can be downloaded.
Witness statements and medical records
Independent witnesses carry weight because they have no stake in the claim. 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. 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.
