Understanding the legal limit of .08 can help you make better choices about driving after having a few drinks. Nationwide, the .08 blood alcohol concentration (BAC) is a standard legal limit for drivers age 21 and over. Driving with a BAC at or above this level means you run the risk of being arrested or causing an accident that injures you or others.
While there are a number of factors playing into how many drinks you can have before you reach the legal limit, the number of shots, beers, cocktails, or glasses of wine is often much lower than people realize. The best choice is always to find another ride if you plan to drink. Even below the legal limit, alcohol will affect your ability to make safe driving decisions.
