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 0.08%. This standard aligns with the national guideline set by the Federal government, which most states adopted to promote road safety and reduce alcohol-related accidents.

When a driver's BAC is at or above this limit, they are presumed to be impaired and can be charged with driving under the influence. It's important to note that even drivers with a BAC below 0.08% can still be charged with DUI if they exhibit impairment due to alcohol consumption.

Understanding this legal threshold is crucial for safe driving practices and compliance with state laws. Thus, knowing that the BAC limit is set at 0.08% emphasizes the significance of making responsible choices regarding alcohol consumption and driving.
