RCMP officers are investigating a head-on collision that took place on the Sea to Sky Highway near Whistler on Friday night.

Around 7 p.m. on January 10, Whistler RCMP received several calls about a two-vehicle collision on Highway 99 near Brandywine Falls in Whistler.

Whistler RCMP and emergency services responded and attended the scene.

Officers learned that a blue Toyota Prius was driving south on Highway 99. Unfortunately, the driver failed to negotiate a curve in the road, and the vehicle slid into oncoming traffic heading north, resulting in a collision with a red GMC Envoy.

Whistler Fire Rescue had to extricate one occupant from a vehicle who was taken to hospital with serious injuries.

Three other individuals, who sustained minor injuries, were able to exit their vehicles themselves.

Whistler RCMP stated that one of the vehicles was not equipped with winter tires, which may have contributed to the collision in addition to poor driving conditions caused by a recent snowfall.

Anyone who witnessed this collision and has not yet spoken to the police is asked to contact the Whistler RCMP at 604 932-3044 or Crime Stoppers.

Meanwhile on the same day, Squamish RCMP had conducted traffic stops for winter-tire checks on Highway 99. Officers checked 816 vehicles and all of them were found to be compliant with regulations.
