Alberta RCMP say drugs and alcohol are believed to be factors in a crash west of Calgary on Friday that injured four people.
Emergency crews were called to a two-vehicle collision on Highway 1 and Highway 22, south of Cochrane, just after 9:30 a.m.
In a news release Friday, RCMP said early indications are that an eastbound car sideswiped a tractor trailer, causing the car to enter the ditch and roll.
RCMP allege the tractor trailer didn’t stop, but said the driver “may not have even been aware” of the crash.
Originally, EMS said two people sustained serious injuries and were taken to hospital and two men were treated on scene.
Later, EMS confirmed four men were taken to hospital, two of whom were treated for minor injuries at Foothills Medical Centre.
RCMP officers at the scene of the crash told Global News first responders had to administer Narcan to the driver before he could be transported to hospital. EMS confirmed Narcan had to be administered to one of the people in the car.
RCMP are asking anyone who may have witnessed the crash, or who may have found damage to their vehicle consistent with being sideswiped, to call the Cochrane detachment at 403-851-8000 or to report anonymously through Crime Stoppers.
