Police Reports, Dashcam Video and Car Accident Evidence
The evidence in a car crash claim starts to scatter within hours. Vehicles get towed and repaired, video gets recorded over and witnesses become harder to find. A car accident attorney usually looks first at 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 crash report
Officers who respond to a crash 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. In many states, drivers must also report crashes involving injury, death or property damage above a set dollar 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, sometimes for a 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. An auto accident attorney will check the report against the photos and statements.
Dashcam video and photographs
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. Scene photos can show where the vehicles stopped and the debris and skid marks around them, while photos of injuries taken over several weeks can document healing.
What the vehicle itself recorded
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, 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 them. Under the Driver Privacy Act of 2015, EDR data generally belongs to the vehicle owner or lessee, and others https://deanpatq247.solsticebrief.com/posts/rear-end-and-t-bone-collisions-how-fault-is-decided 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 a car accident attorney may send a preservation letter asking that the vehicle be held until the data is downloaded.
Witnesses 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 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 is general information rather than legal advice, and no result can be predicted from it.
