Frequently Asked Questions
Why do chain-reaction crashes happen?
They typically start when one vehicle slows or stops unexpectedly, and the vehicles behind it do not have enough space or time to react, resulting in a chain of collisions.
How can drivers avoid being caught in a pile-up?
Keeping a safe following distance, watching brake lights several cars ahead, and slowing early when traffic bunches up can help drivers react before a chain reaction reaches them.
What should I do if I'm stopped near a crash on the highway?
Stay inside your vehicle if it's safe to do so, turn on hazard lights, and avoid standing in traffic lanes. If you must get out, move well onto the shoulder away from moving vehicles.
What to Do After a Multi-Vehicle Crash in Montclair, CA
After a multi-vehicle crash, check yourself and any passengers for injuries before stepping out of the vehicle, and move to the shoulder if it's safe. Call 911 even if damage looks minor, since injuries like whiplash or internal bruising aren't always obvious right away. Exchange information with the other drivers involved, take photos of the vehicles and surroundings if you're able, and ask for a copy of the CHP incident report once it's available. A follow-up visit with a doctor in the days that follow is worth it, even if you feel fine at the scene.
