Frequently Asked Questions
What typically causes a pile-up involving several vehicles?
These crashes sometimes start with one vehicle slowing or stopping suddenly, sometimes because of traffic ahead, debris, or a mechanical problem, and other drivers following too closely don't have time to react.
Why do chain-reaction crashes happen on highways like I-79?
High speeds and short following distances leave little time to stop once one vehicle brakes hard, so a single slowdown can trigger a series of collisions behind it.
What should I do if I come upon a crash scene on the highway?
Slow down well before reaching the scene, turn on hazard lights to warn drivers behind you, and move into a lane away from the crash if it's safe to do so. Avoid stopping to look, and follow any instructions from responders or signage directing traffic.
What to Do After a Multi-Vehicle Crash in South Fayette Township, PA
If you're involved in a multi-vehicle crash, try to move to a safe spot away from traffic if your vehicle is drivable and it's safe to do so. Check yourself and any passengers for injuries, and call 911 even if injuries seem minor, since some symptoms take hours to appear. Exchange information with other drivers involved and note any details you can, such as lane positions and what you saw happen. A medical check soon after the crash can catch injuries like whiplash or internal bruising before they worsen. Keep copies of any police report and medical records in case you need them later.
