Whislter RCMP expect to lay charges against a driver they suspect fell asleep at the wheel causing a four car pileup and closing down the Sea to Sky Highway last Thursday (July 19) afternoon.

The accident occurred north of Brandywine Falls shortly before 4 p.m. said Sgt. Rob Knapton shutting the highway for two hours before it could be reopened to single lane traffic only.

A northbound vehicle on the highway crossed the centre line, hitting a vehicle travelling southbound and continuing to his a second vehicle afterwards. That second vehicle was then hit by a third southbound vehicle that was unable to stop.

“It looks like the driver of the northbound vehicle likely fell asleep and crossed the centre line,” Knapton said adding the two passengers in that vehicle were not injured.

Lower Mainland traffic services were on scene but he said he expects charges, which could be criminal or motor vehicle act related, to be laid once that investigation is complete.

Three people were transferred to Vancouver General hospital by B.C. Ambulance Service helicopter one with a head injury.

Knapton said that person was suspected to have a concussion but is fine now and the other people were taken out of precaution, as one was an elderly female and the third diabetic.

“We were vey lucky with how everyone turned out – it could have been much worse than it was.”

Nine other individuals involved in the accident were treated at the scene scene.
