RCMP say a car and a commercial vehicle were travelling in opposite directions, and they collided on a curved stretch of the highway Sunday morning.
Collision analyst Sgt. Brian Nightingale says the conditions on the snow-covered highway are "treacherous."
He could not say if the victim was a driver or a passenger, or which vehicle they were travelling in.
Nightingale says Mounties hope to have traffic open to a single lane later Sunday.
Highway 1 was open 10 kilometres west of Salmon Arm to single-lane alternating traffic as of Sunday afternoon. (CFJC)
