Although the driver possesses a Commercial Driver License (CDL), the stricter statutory limit of 0.04%0.04\% applies exclusively when actively operating a commercial motor vehicle.

Adım Adım Çözüm

1
Identify the driver's age and the type of vehicle being operated
The driver is 35 years old (adult aged 21+) and is operating a private non-commercial vehicle.
Statutory BAC limits are determined by the classification of the vehicle being driven and the driver's age, rather than license class alone.
2
Determine the applicable legal per se BAC threshold
The applicable statutory limit is 0.08%0.08\%.
While CDL holders are held to a stricter 0.04%0.04\% BAC limit when driving a commercial motor vehicle, the standard adult 0.08%0.08\% limit applies when they drive a private passenger vehicle.
