Calgary police are warning drivers they'll be out in full force this holiday season to make sure people are not getting behind the wheel after drinking.
Police will be out both day and night conducting random traffic stops in their search for impaired drivers.
This year, they're dubbing it "Operation SAIL," which is an acronym for: Save An Innocent Life.
Faryal Shah started SAIL in honor of Arsh Brar — a fellow University of Calgary student killed by a drunk driver.
"I always talk about him and he was super-ambitious," Shah said. "He was definitely going places, (he was) so business-minded. He would have made the big bucks for sure. So it was not only a loss to us…it’s also a loss to society, and who knows what he could have done — what he could have become, and now we never will know either."
On Wednesday night, police set up a checkstop at Country Hills Blvd. and Beddington Trail NW between 9:30 p.m. and 11:30 p.m. One woman registered double the legal limit, while three people were handed 24-hour suspensions for registering a blood-alcohol level between .05 and .08.
Last year, Calgary police stopped 5,500 cars with the checkstop program, resulting in four impaired driving charges.
