Difficulty: MediumBlood Alcohol Concentration (BAC) Limits and Thresholds

Under standard traffic safety regulations, a driver aged 21 or older operating a personal non-commercial motor vehicle is legally below the statutory per se Blood Alcohol Concentration (BAC) limit if their chemical test result is 0.07%.

Answer: Answer

Answer

The statement is True. For drivers aged 21 or older operating a non-commercial vehicle, the standard statutory per se BAC threshold is 0.08%. A level of 0.07% is below this limit.
The statement is true because standard state traffic laws establish a statutory per se legal BAC limit of 0.08% for non-commercial drivers who are at least 21 years old. Therefore, a measured BAC of 0.07% remains under the standard statutory limit.

Step-by-Step Solution

1
Identify the driver classification and vehicle type in the statement
The driver is aged 21 or older operating a personal non-commercial vehicle.
BAC limits vary by driver category (e.g., adult non-commercial, commercial operator, underage driver).
2
Recall the statutory BAC limit for adult non-commercial drivers
The statutory per se impairment threshold for this driver category is 0.08%.
This is the established legal limit across standard state DMV regulations for adult non-commercial drivers.
3
Compare the tested BAC result to the statutory threshold
0.07% is strictly less than 0.08%.
Because 0.07% does not reach or exceed 0.08%, the driver is legally below the standard per se limit.
