Question

Difficulty: MediumBlood Alcohol Concentration (BAC) Limits and Thresholds

When operating a commercial motor vehicle that requires a Commercial Driver License (CDL), a driver is legally considered impaired per se if their Blood Alcohol Concentration (BAC) reaches or exceeds 0.04%.

Answer: Answer

Answer

The statement is True. Operating a commercial motor vehicle with a BAC of 0.04% or higher constitutes per se driving under the influence.
The statement is True because traffic safety laws enforce a 0.04% per se Blood Alcohol Concentration limit for drivers operating commercial motor vehicles.

Step-by-Step Solution

1
Identify the driver classification and vehicle operation type in the statement.
The statement specifies a motorist operating a commercial motor vehicle that requires a CDL.
Traffic laws categorize statutory BAC thresholds based on driver age and vehicle classification.
2
Recall the statutory BAC limit applicable to commercial motor vehicle operation.
The statutory per se BAC limit for commercial vehicle operation is 0.04%.
Due to the size, weight, and risk associated with commercial transport, commercial operators are held to a lower BAC limit than standard non-commercial drivers (0.08%).
3
Compare the recalled threshold with the value given in the statement.
The statement correctly identifies 0.04% as the per se BAC limit.
Because the stated threshold aligns exactly with statutory driver knowledge regulations, the statement is True.
