Why is drinking alcohol dangerous while driving?

Driving after drinking affects your ability to think clearly and judge what’s happening on the road. Alcohol dulls the brain’s judgment, so you’re less able to assess risks, decide when to brake or accelerate, and maintain steady control of your vehicle. You might feel you’re fine, but your awareness of how much you’ve had and your actual driving ability can be far from reality, leading to dangerous decisions and missed hazards. That’s why the best choice is that alcohol impairs judgment and makes it hard to know when you’ve had too much to drink. It doesn’t make you more careful about speed; in fact, it often causes erratic or unsafe speed changes. It also doesn’t improve your ability to judge distances; it worsens depth perception and reaction time. And it doesn’t reliably reduce sleepiness—alcohol typically decreases alertness and can make you more tired.
