Evidence After a Car Crash: Police Reports and Dashcam Video

Police Reports, Dashcam Video and Car Accident Evidence

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, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.

What the police report contains

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. 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, 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. States differ on whether an officer's opinions can be used at trial. 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 accident lawyer will compare the report with the photos and statements.

Photos and dashcam footage

Dashcam video can show the moments before a crash more clearly than any witness. Save the original file with its date and time stamp, rather than a phone recording of the screen, and store a backup copy. Nearby businesses, buses and traffic cameras may have recorded the crash too, 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.

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, seconds rather than minutes, surrounding 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 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 https://rowanyyna325.stonefielddigest.com/posts/how-fault-works-in-rear-end-and-t-bone-car-accidents-2 attorney may send a preservation letter asking that the vehicle be held until the data can be 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 gaps in treatment are often used by insurers 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.
