Frequently Asked Questions
What should I do immediately after a car accident?
Move to a safe spot if possible, check for injuries, and call 911. Exchange information with other drivers and avoid discussing fault at the scene. Seek a medical check even if you feel fine, since some injuries aren't immediately obvious.
Where do most traffic accidents happen?
Many crashes occur on highways and interstates during peak travel times, usually involving multiple vehicles in a single lane or merge area. Interchanges and lane-blocking incidents like this one can cause sudden slowdowns that catch following drivers off guard.
What injuries are most common in car accidents?
Neck and back strain, whiplash, and bruising from seatbelts or airbags are common, along with cuts from broken glass. More serious crashes can cause broken bones or head injuries, which is why medical evaluation after any collision is important.
What to Do After a Car Accident in Olympia, WA
If you're involved in a crash on a highway like I-5, try to get your vehicle out of traffic lanes if it's safe to do so, and turn on hazard lights to warn oncoming cars. Stay inside your vehicle if traffic is still moving nearby until help arrives. Once you're safe, get checked by a medical provider, keep a copy of the police report, and hold onto any photos or notes from the scene. Even in Olympia's lighter traffic stretches, a northbound I-5 lane closure can back up quickly, so patience and caution matter for everyone waiting behind the scene.
