Answer

0.08%
For adult drivers aged 21 and older operating a standard non-commercial vehicle, driving with a Blood Alcohol Concentration (BAC) of 0.08% or higher is illegal per se in all states.

Step-by-Step Solution

Identify the driver's age category and license type
The driver is age 21 or older operating a non-commercial passenger vehicle.
Statutory BAC limits vary depending on age and commercial driver classification.
