Emergency crews responded to a three-vehicle crash on Highway 1 westbound east of Prest Road, just before noon on Monday following a major snowfall in Chilliwack.
Traffic slowed to a crawl as only one lane remained open for vehicles to pass. The cable barrier running down the median was damaged as a result of the collision.
One person was taken to hospital with injuries.
RCMP are advising motorists to stay off Highway 1, east of 232 Street.
Police have instructed tow companies not to remove vehicles that have gone off road at this point. Tow trucks are only removing vehicles that pose a hazard to the flow of traffic.
“I want to remind drivers they are required by law to slow down when passing emergency vehicles pulled over on the side of the road, or tow trucks,” says RCMP spokesperson Sgt. Peter Thiessen.
