A new law says that 2 hours AFTER you've been driving. Police can show up at your home, force you to do a breathalizer and charge you with drunk driving. Had a long day at work in the Summer and headed home for a nice BBQ and a beer? You better hope you don't drink too much or you could be charged with drunk driving, AFTER you've gone home and are unwinding, even if you didn't have a drop of alcohol in your system when you were on the road. I don't drink much at all, so this doesn't effect me. This, however, is the microcosm of more to come. Police in Canada can now demand breath samples in bars, at home It may sound unbelievable, but Canada’s revised laws on impaired driving could see police demand breath samples from people in bars, restaurants, or even at home. And if you say no, you could be arrested, face a criminal record, ordered to pay a fine, and subjected to a driving suspension. You could be in violation of the impaired driving laws even two hours after you’ve been driving. Now, the onus is on drivers to prove they weren’t impaired when they were on the road.
