Determining fault in a head-on collision involves a detailed investigation by various parties, including the police, insurance adjusters, and possibly accident reconstruction experts. They will evaluate evidence such as traffic laws, witness statements, vehicle damage, and physical evidence from the scene. If available, traffic camera footage or surveillance videos may also play a crucial role. The position of vehicles, skid marks, and impact points help understand the collision’s dynamics. An attorney can assist in interpreting this evidence and working with experts to build a solid case establishing the fault.
