What happened

The semi-truck was travelling eastbound on State Route 18 when its brakes failed, according to the Washington State Patrol. The truck then hit several vehicles, leaving seven vehicles involved in the crash.

Several people were hurt in the collision and were taken to hospital. No deaths were reported in the initial coverage. Troopers closed all eastbound lanes while emergency crews worked at the scene, and traffic was diverted. The highway reopened at about 10:40 am.

Why brake failure is so dangerous

A fully loaded semi-truck needs a far longer stopping distance than a car, and that distance grows sharply when brakes fail or fade on a downhill stretch. When a heavy truck cannot slow down, the driver has very few options: the truck keeps gaining speed, and any vehicles ahead have little time to move out of the way.

That is why commercial vehicles are subject to regular brake inspections and maintenance checks, and why drivers are trained to use lower gears and runaway-truck ramps where they are provided. Investigators will normally examine the truck's brake system, maintenance records and the driver's account as part of the follow-up to a crash like this one.

If you drive behind heavy vehicles

• Keep a generous following distance behind trucks — you need room to stop if they slow suddenly
• Never cut in front of a truck and brake sharply; a loaded truck cannot stop as quickly as a car
• On downhill stretches, stay alert for trucks moving faster than the flow of traffic
• If you see a truck in trouble, move away calmly if it is safe and call emergency services
