What BAC range applies to Commercial Vehicle 2?

• A. 0.06-0.08
• B. 0.04-0.06
• C. 0.02-0.04
• D. 0.08-0.10

Answer: (A)

Different commercial vehicle categories have specific blood alcohol concentration (BAC) ranges used to gauge impairment for that class. For Commercial Vehicle 2, the assigned range is 0.06% to 0.08%. This means a driver whose BAC falls within that band is considered impaired under the rules for CV 2. The reason this is the right range is that it sits between lower impairment bands used for other classifications (such as 0.04%–0.06%) and higher bands (like 0.08%–0.10%), reflecting a distinct threshold chosen for CV 2. In this range, impairment is recognized enough to impact safe operation of heavier vehicles, without jumping to the higher impairment band.
