A head-on collision on Glover Road Wednesday night sent two people to hospital, Langley RCMP say.
Police were called about an erratic driver westbound on the Trans Canada Highway just after 10 p.m., said Cpl. Holly Largy, spokesperson for the local RCMP.
The red Mazda RX8 had just left the highway and headed down Glover Road.
After crossing Crush Crescent, the car was seen to make a complete U-turn and drive into the oncoming lane.
It slammed into a northbound vehicle, Largy said.
The Mazda driver, a 63-year-old Pitt Meadows man, was taken to hospital and is in critical condition.
A 28-year-old Langley woman in the other car was also hospitalized, but her injuries are less serious, Largy said.
The investigation is ongoing, but police believe the Mazda driver may have been impaired by drugs at the time of the crash, Largy said.
Any witnesses or anyone with additional information who have not yet spoken to the police are asked to call the Langley RCMP at 604-532-3200.
