A 3-minute lesson from the Florida course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Alcohol weakens every skill driving needs: judgment, reaction, vision and concentration. It works fast and starts with your judgment, so the first thing you lose is the ability to notice you're impaired.
Know the rule
Alcohol is absorbed into the lining of the stomach, passes directly into the bloodstream, and reaches your brain within minutes after you drink.
Even one drink can affect your driving and makes a crash much more likely. No one can drink alcohol and drive safely, however many years they have been driving.
After a party your friend insists he feels fine after 'only a couple.' His judgment is the first thing alcohol affects, so his opinion of himself can't be trusted. Take his keys and get him a rideshare or a sober driver.
