Tougher penalties come into effect for drinking and driving in Alberta this weekend however Calgary Police say that won't mean a big change in their operations. Acting Inspector Michael Waterston says don't expect to see a festival of check stops all over the city when the new provincial penalties come into effect Saturday. He says the current policy of year-round checkstops four times a week will continue and officers will just have greater powers to get drivers off the road who blow between .05 and .08 with the new rules. He says clearly it is so important that individuals that do choose to go out and consume alcohol have a plan "B". Currently officers have discretion to hand out 24 hour license suspensions for blowing between .05 and .08, the new rules will see a three day suspension and three day vehicle seizure for the first offence. A second offence means a 15 day license suspension and your vehicle is gone for seven days and a third offence is a 30 day suspension.
