After a T-bone collision, it is very common for both drivers to insist they had the right-of-way, and it will take a review of the evidence to establish who was at fault. An experienced car accident attorney will build a case for liability using resources like: The Police Report: Police officers called to the scene of a T-bone accident will write their preliminary assessment of what caused the crash, including whether the drivers were speeding or under the influence of alcohol. The report will also document important information like contact details for witnesses, a diagram of how the cars were situated right after the crash, and any important physical evidence found at the scene. Video of the crash: Footage of the point of impact is often available from traffic cameras, dash cams, or even the exterior security cameras of local businesses. Witnesses: When there is a hotly disputed argument about who had the right-of-way, the statements from bystanders or fellow motorists can help resolve what happened in the lead-up to the collision. Forensic Car Accident Experts: Your car accident lawyer can hire accident reconstructionists to analyze the evidence and provide expert testimony about the causes of the crash and who should be liable. Data from on-board devices: The monitoring recorders that come standard with modern vehicles will preserve crucial information about the car's behavior immediately before a crash. Your car accident lawyer can download, analyze, and use this data to establish key facts about the collision.
