RCMP are investigating a serious, single-vehicle crash that sent a woman to hospital.

On Saturday around 4:15 a.m., police were on patrol on Roblin Boulevard in the RM of Headingley when they spotted a vehicle in the ditch.

According to police, the car was travelling eastbound when the vehicle hit a driveway approach and flipped into the ditc, where it hit a large tree and a light pole.

The 24-year-old male driver was able to get out, but the 25-year-old female passenger was trapped inside and had to be extracted from the vehicle, RCMP said.

The woman was transported to Winnipeg hospital with serious injuries, where she remains in stable condition.

Police believe alcohol is a factor in the crash. They said both the man and woman were wearing seatbelts.

A Forensic Collision Reconstructionist is assisting with the ongoing investigation.
