Evidence After a Car Accident: Police Reports and Dashcam Video
By @alexisnsaj856
The evidence in a car crash claim starts to scatter within hours. Cars are towed and repaired, video gets recorded over 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.
The police report
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, 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, sometimes for a fee.
Insurers rely heavily on the crash report, but it is not the final word on fault. Rules on using an officer's opinions at trial vary by state. 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.
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 https://martinrxsu450.lowescouponn.com/choosing-an-auto-accident-attorney-questions-to-ask and time stamp, rather than a phone recording of the screen, and make 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. 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 event data recorder
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. Insurers often move a total loss vehicle to a salvage auction quickly, so a motor vehicle accident lawyer 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
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. 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 article is general information, not legal advice, and it does not predict the result of any claim.
