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

In Arizona, the legal blood alcohol concentration (BAC) limit for drivers aged 21 and over is set at 0.08%. This limit is consistent with the nationwide standard established in many states to indicate impaired driving. At or above this BAC level, a driver is presumed to be unable to operate a vehicle safely, which can lead to legal penalties, including fines, license suspension, and possible imprisonment.

Maintaining this limit is essential for road safety, as alcohol affects cognitive functions, motor skills, and reaction times, significantly increasing the risk of accidents. Understanding and adhering to this BAC limit is crucial for all drivers to ensure they are operating their vehicles legally and safely.

Other options reflect BAC levels that are either below the legal limit or above, which do not apply to the standard policy for legal intoxication for drivers in Arizona.
