What Can Contribute to Multi-Vehicle Freeway Crashes?
Multi-vehicle crashes can happen when drivers have limited time to react to sudden hazards, disabled vehicles, or unexpected changes in traffic flow. Tire failures, debris, and rapid lane changes may also create conditions that increase the chance of additional vehicles becoming involved.
Freeway crash investigations generally include an examination of vehicle damage, roadway evidence, tire conditions, and the positions of the vehicles after impact. Investigators may also review witness statements, traffic camera footage, and road conditions to better understand the sequence of events and identify any factors that contributed to the collision.
