RCMP and Alberta sheriffs plant to crack down on driving infractions over the Labour Day long weekend.

Traffic units across the province will be out on the roads watching for speeders, impaired drivers and people not wearing seatbelts, said Sheriff Jason Graw.

It has already been a busy summer for traffic officers. Over the Heritage Day long weekend, RCMP handed out close to 3,500 speeding tickets.

Graw says a lot of people ignore the rules of safe driving during holidays.

"Driving is a serious and complex task. Long weekends in Alberta are typically the busiest times for us. We see a rise in serious injury and fatal collisions caused by alcohol, for example, on long weekends,” he said.

About 90 per cent of collisions in Alberta are caused by driver error, Graw said.
