Why Can Secondary Crashes Happen After an Initial Collision?
A secondary crash can occur when drivers approach the scene of an earlier collision and encounter stopped vehicles, debris, or lane restrictions. Reduced visibility can make these hazards harder to see in time. Traffic may also slow suddenly as drivers pass the first crash scene.
Drivers approaching an active crash should reduce speed and leave additional space from vehicles ahead. Sudden braking or lane changes can create new risks. Staying focused on the roadway is especially important when emergency vehicles or damaged cars are nearby.
Freeway crashes can also create debris across several lanes. Tow truck crews and emergency workers may need to close lanes while vehicles are removed. Drivers should follow temporary traffic controls and allow extra room around response activity.
