Despite campaigns and activism from groups like MADD (Mothers Against Drunk Driving), a lot of people still drive while under the influence of alcohol.
Canadian police caught 90,000 impaired drivers in 2011, according to Stats Canada, and the rate of impaired driving was up 2 per cent from 2010, CBC News reported in January.
And according to some estimates, an average of 800 Canadians are killed by drunk drivers each year, The Globe and Mail reports.
Sometimes it seems like shock tactics are needed to remind people that driving drunk can be deadly - and that's where videos like this one, a British ad titled #PubLooShocker, come in.
It was created by the UK's Department for Transport in collaboration with ad agency Leo Burnett London.
The video (which features paid actors, by the way, not unsuspecting members of the public), shows three guys using the facilities at a pub, when they get a grisly surprise.
It makes for one creepy trip to the washroom. Judging by some of the comments on YouTube, there's disagreement about whether this ad is an effective way to combat drunk driving.
For instance, romanmir01 writes, "This does NOTHING to stop drinking and driving, but here is a possible impact for you: people will no longer visit public washrooms or if they do, they won't wash their hands there."
Others were much more supportive of the ad: "The idea is to mimic how drunk driving can effect your night out," said user Bruno Rodriguez. "I think it's pretty damn effective."
Whether or not it will deter drunk drivers remains to be seen - but the ad is certainly getting a lot of attention, racking up nearly four and a half million views since its release on June 6.
