A pedestrian was hit by a vehicle and remained on the ground in the 20600-block of Dewdney Trunk Road in Maple Ridge around 7:30 p.m. Saturday.
An SUV traveling eastbound hit a man when he stepped off the sidewalk.
According to a witness, crews arrived to find a pedestrian down on the ground in front of a bus stop.
The pedestrian was unconscious and transported to Royal Columbian Hospital with serious injuries, said Curtis Kreklau, South Fraser News Services.
A white van, parked just down the block from the scene, and a Mercedes SUV, at the scene, were examined by RCMP traffic analysts as they closed Dewdney for several hours to investigate.
The driver of the SUV is cooperating with police.
The man hit is still alive and the investigation is ongoing, said Ridge Meadows RCMP, who would not comment further on the his injuries.
Kreklau said the Maple Ridge incident was the third serious collision involving pedestrians Saturday, starting with a pedestrian hit in a rollover in Langley at 200 Street and 66 Avenue just before noon.
A pedestrian struck and killed in Surrey around 4:45 p.m., in the 14600-block 108 Avenue.
