Police Reports, Dashcam Video and Car Crash Evidence

The evidence in a car crash claim starts to scatter within hours. Vehicles get towed and repaired, video is overwritten and witnesses become hard to reach. 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.

What the police report contains

When officers respond to a crash, they usually prepare a crash report, often called a police report. It usually records who was driving each vehicle and which insurer covers it, 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 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 check the report against the photos and statements.

Dashcam video and photographs

Dashcam video can show the moments 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. Nearby businesses, buses and traffic cameras may have recorded the crash too, but many systems overwrite 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 car's own black box

Many passenger vehicles have an event data recorder (EDR). https://caraccidentlawyers.wiki/reference/whiplash-and-soft-tissue-injuries/ 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 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 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.
