Evidence After a Car Crash: Police Reports and Dashcam Video
By @andreapwb805
Evidence from a car crash starts to disappear within hours. Cars are towed and repaired, video gets recorded over and witnesses become hard to reach. A car accident lawyer usually looks first at 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 crash report
Officers who respond to a crash 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, whether that is a city police department, a sheriff's office or the state highway patrol, often for a small fee.
A crash report is influential in insurance claims, but it does not decide fault. Rules on using an officer's opinions at trial vary by state. 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 accident lawyer 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. Save the original file with its date and time stamp, 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. 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 passenger vehicles have 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 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 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 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 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 https://caraccidentlawyers.wiki/reference/rear-end-collisions/ 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. This article is general information, not legal advice, and it does not predict the result of any claim.
