What this actually means for you
Driving asks for your attention in a way almost nothing else in daily life does — full, continuous, and for the whole trip, not just the tricky parts. Some drivers believe that if they are impaired, they will drive slowly and reach their destination safely. It cannot be faked or crammed the night before a test. It is a habit you either build in your first months of driving or spend years unlearning the opposite.
Myths and Facts About Impaired Driving | Alcohol and Cannabis Effects

I will drive slowly
Some drivers believe that if they are impaired, they will drive slowly and reach their destination safely. It is far from the truth; moving slowly, especially on highways, is extremely dangerous and can get them in trouble with the police.
By driving slowly, the driver makes it difficult for vehicles behind them. They may begin to tailgate or aggressively overtake them.
If the driver is impaired, stay away from the wheel.
The same applies to taking back roads.
If he can, so can I
Some people think that if one person can drive after having a drink, they should.
The driver must realize that everyone is different and responds to situations differently.
For example, alcohol – one driver may remain attentive and focused with a 0.08 BAC. However, another driver may be unable to open his eyes with a 0.02 BAC.
The driver must know their limits and accommodate them accordingly. Do not take any chances with safety.
Sobering up
It can take up to three hours for the effects of alcohol to kick in fully. The time it takes to sober up depends on the individual, which can take up to 24 hours.
The driver must be aware of their capacity, know how their body reacts to alcohol, and accommodate accordingly.
Also, it will take time to sober up. Drinking water or ‘'recovery fluids will not help; you must not drive thinking you have sobered up.
Peer pressure
Some people may think they have no choice when faced with pressure from friends to drink.
The driver always has a choice; they can deflect their requests with any excuse and accept that the driver will not drink while driving.
If the driver does end up drinking, ensure they arrange for another mode of transport.
Wine
Some people consider wine to be less alcoholic than other drinks. However, this is false; wine is just as capable as any other drink of disorienting the driver.
Please do not underestimate alcohol when mixing it with driving.

Using this on Ontario roads — and on your road test
Ontario law treats this seriously: distracted driving penalties are steep, and novice drivers face licence suspensions on top of fines. But the legal risk is honestly the smaller one — a car at 60 km/h covers the length of a basketball court in about two seconds, and a lot can step into that space. In the GTA the demands never stop: transit stops, cyclists, pedestrians looking at their own phones, delivery riders filtering through traffic. Set the car up before you move — seat, mirrors, phone away and silent, route planned — so that once you are rolling, your attention has only one job.
