What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in Arizona?

In Arizona, the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 is established at 0.08%. This is a standard limit that aligns with many other states in the United States, and it is significant because it defines the maximum allowable level of alcohol a driver can have in their system while operating a vehicle.

A BAC of 0.08% indicates that there is enough alcohol in a person's bloodstream to impair their ability to drive safely and increases the likelihood of accidents. Law enforcement actively conducts sobriety checkpoints and other measures to enforce this law, and penalties can be severe for those caught driving with a BAC at or above this limit.

Understanding this limit is crucial for safe driving practices and helps reinforce the importance of responsible alcohol consumption.
