Legal Blood Alcohol Limit By State

What is the Legal Limit in your State?

In every state, it is a crime to operate a motor vehicle while under the influence of alcohol or drugs; however, drunk driving penalties differ by state.

Depending on where you live, your state may impose enhanced DUI penalties for certain BAC levels.

Many states have also enacted zero tolerance laws for underage drinking and driving, but zero doesn't always mean zero. In some states, zero means .01% or greater and in others is means .02% or greater. In a few states, zero actually means zero.
