Many drivers in Arizona enjoy a drink from time to time. However, it is always important to bear in mind the legal limits for blood alcohol concentration when driving. The limit is generally 0.08 percent, although it can be even lower for commercial drivers or drivers under the legal drinking age. If you are found driving with a BAC which is equal to or in excess of the limit, you could be charged with drunk driving.

Of course, you may be someone with a high alcohol tolerance. Some people take far longer to experience significant impairment from intoxication. However, it is vital to remember that DUI laws BAC tests are not concerned with how functional you are after drinking a certain amount of alcohol.
