Frequently Asked Questions
What typically causes crashes involving three or more vehicles?
These incidents usually start with one vehicle slowing, stopping or losing control, which gives following drivers too little time or space to react before additional vehicles collide.
Why does one crash sometimes trigger a chain reaction involving multiple cars?
Limited following distance, high speeds, and reduced visibility (from weather, glare, or traffic backups) can turn a single collision into a chain-reaction event before drivers behind can brake or steer clear.
What should drivers do if they come upon a crash scene on the highway?
Slow down well before reaching the scene, watch for emergency vehicles and personnel in the roadway, and follow any detour or lane-closure instructions from responders to avoid adding to the hazard.
