Police are investigating a dramatic accident in Cloverdale Thursday afternoon.
At about 3:30 p.m., a semi truck rear ended a five-ton truck on 176 Street, just south of Fraser Highway.
The five-ton truck toppled on its side into a ditch.
The semi then swerved into a pick up truck before it came to rest.
Two people in the semi and two people in the five ton truck were taken to hospital with non-life threatening injuries.
Speed and alcohol are not likely contributing factors.
"It appears that driver attention might be a factor," said Surrey RCMP Cpl. Scotty Schumann. "That's something that detectives will be looking at."
