The SQ and Montreal police launched spot checks this week in an effort to stop the prevalence of drunk driving during the holidays.

The Surete du Quebec set up a roadblock on Friday night right on westbound Ville Marie Expressway – and for anyone trying to bypass it, Montreal police were waiting along St-Antoine St.

Drivers should get used to the annual roadblocks, said Andre Durocher of the Montreal police.

“This is the beginning of the holiday season. This is the season to be jolly, but also to be sober… when you take your vehicle. Don't drink and drive,” said Durocher.

As many as 75 per cent of the people arrested for DUI are first-time offenders. Most of the time, they're barely over the legal limit.

“Imagine you've gone on all your life without a criminal record and you get caught because you had one glass too many. It's not worth it,” said Durocher.

Police officers are trained to spot people who may have been drinking. Technology also allows police to spot people who may have consumed drugs. 

Some people pulled over this weekend were surprised to find out how strict the laws are, and how little it takes to raise a red flag, though most agreed with the police operation.

Everything's fine when you have nothing to hide,” said one driver.

The operation did create some traffic jams, and motorists were not aware of what was going on until they reached the actual roadblock, but most showed understanding at a time when few have patience for drunk drivers.

“We need to get them off the road,” said another driver.

Expect these spot checks to appear randomly throughout the holiday season.

If you’re driving, don’t drink. And if you’re drinking there are many safer options to get home: take a taxi, call a friend, use public transportation, or use Operation Nez Rouge.
