Prince Albert Police are trying to piece together the final moments before a fatal crash in near the entrance of Little Red River Park on Highway 55. 

Officers say a 24-year-old was walking on the side of the road when he was struck by a vehicle. He was pronounced dead at the scene. 

"It was established that the pedestrian was outside a vehicle for whatever reason, and that reason is still under investigation, and an eastbound vehicle struck him," said Staff Sgt. Dave Schluff.

Schluff said the man was a passenger of a pickup truck, but he had gotten out of the vehicle at some point.

The woman driving the pickup remained in the vehicle and was unharmed.

Police have re-opened Highway 55 after they had closed a section in the area off  for most of Saturday morning while traffic reconstructionists gathered evidence. 

At this point it's not clear why the man left the vehicle.

Schluff is reminding all drivers and passengers who pull over on the side of the highway to use caution. 

"If you have a vehicle problem pull over as far as you can to the side of the road and be very weary of traffic because again the speeds are way greater than in the city," he said. 

The man's name has not been released. 

No charges have been laid in the crash.
