According to Arizona law, a person may be presumed impaired with a BAC of what level?

In Arizona, a blood alcohol concentration (BAC) of .08 or more is the level at which an individual is presumed to be impaired for the purposes of driving. This legal standard aligns with many other states in the U.S., which also set the .08 BAC threshold as a clear indicator of impairment. This means that if a driver is found to have a BAC at or above this level, they can be charged with driving under the influence (DUI) regardless of additional evidence of impairment.

It is important to note that lower BAC levels can still lead to charges depending on the facts of the case, especially for drivers under the legal drinking age or those operating commercial vehicles, which may have stricter standards. However, the .08 BAC level serves as the primary benchmark for general adult drivers in Arizona according to state law.
