Can I Drive the Morning After Drinking?

The 10-second answer

A hangover can affect your focus, choices, and movement. No set number of hours proves you can drive safely; when in doubt, don't.

The simple answer

Here's the careful truth. A hangover itself can make it harder to pay attention, make choices, and move well. Alcohol may still be in your body the next morning. There is no honest number of hours that proves you are safe to drive. If you have any doubt, don't drive. And never drive after drinking.
