Police Reports, Dashcam Video and Car Crash Evidence
Evidence from a car crash starts to disappear within hours. Cars are towed and repaired, video is overwritten and witnesses become hard to reach. A car accident attorney 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
Officers who respond to a crash usually prepare a crash report, sometimes called a police report. It usually records who was driving each vehicle and which insurer covers it, and it often includes a diagram, a short narrative and any citations. 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.
Insurers rely heavily on the crash report, 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 check the report against the photos and statements.
Dashcam video and photographs
Dashcam footage can capture the seconds before a crash better than a witness can. 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.
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 https://lanehseq953.currentvale.com/posts/rear-end-and-t-bone-collisions-how-fault-is-decided and occupant information for a brief period, measured in seconds, not 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 others may access it only in limited situations, such as with the owner's consent or a court order.
EDR data can be lost if the car is repaired or crushed. Total loss vehicles are often moved to salvage auctions within weeks, so a car accident attorney may send a preservation letter asking the insurer or tow yard to hold the vehicle until the data is downloaded.
Witness statements and medical records
Witnesses with no stake in the claim often carry weight. 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. A simple file with the claim number and a log of every call with 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.
