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 harder to find. A car accident attorney usually looks first at the police report, photos, video and the data stored in the vehicles. Here is how each source fits into a claim.
The crash report
When officers respond to a crash, they 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, whether that is 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. 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 check the report against the photos and statements.
Video and photo evidence
Dashcam footage can capture the seconds 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. Photos taken at the scene show vehicle positions, debris, skid marks and road signs, 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, 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 https://caraccidentlawyers.wiki/geography/united-states/georgia/metro-atlanta/johns-creek/ 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 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
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 link 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.
