RCMP want to make sure motorists are safe this Labour Day long weekend.

Officers are reminding residents to watch their speed and not consume drugs or alcohol when they have plans to be behind the wheel.

Speed and impairment are a leading cause of death on Alberta roads.

According to RCMP, during the Labour Day weekend last year there were 394 collisions reported in Alberta with four of them being fatalities and 47 of them involving injuries.

Speeding was believed to be a factor in at least one out of five fatal MVC's in 2017 with alcohol or drug impairment being a factor in at least one out of three crashes.

Motorists are also being reminded to be patient on highways and give themselves plenty of time to arrive at their destinations.
