  1. A
    0.02%
  2. B
    0.04%
  3. 0.08%Answer
  4. D
    0.10%

Answer

A Blood Alcohol Concentration (BAC) of 0.08%0.08\% or higher is the statutory legal threshold for non-commercial drivers aged 21 and older.
For adult drivers aged 21 and older operating non-commercial motor vehicles, statutory traffic safety laws establish that a Blood Alcohol Concentration (BAC) of 0.08%0.08\% or higher constitutes per se legal impairment.

Step-by-Step Solution

1
Identify the driver classification and age group from the scenario.
The driver is 25 years old (adult) operating a non-commercial vehicle.
Statutory BAC limits vary depending on whether the driver is under 21, operating a commercial vehicle, or an adult driving a standard vehicle.
2
Recall the legal BAC threshold established for adult non-commercial drivers.
The statutory per se limit for adult non-commercial drivers is 0.08%0.08\%.
Testing at or above 0.08%0.08\% BAC legally establishes driving under the influence without requiring additional proof of impaired vehicle control.
