How many hours do you have to wait to drive after drinking alcohol?

There is no set amount of hours you can wait. Alcohol takes time to leave the body, so drinking coffee or waiting a few hours won’t make any difference. Depending on the amount of alcohol, you may even be unfit to drive the day after. However, due to the serious penalties of drunk driving in the United States, we strongly recommend that you wait a few extra hours if you're unsure.
