What happens if testing shows a commercial driver has a detectable amount of alcohol below 0.04 percent?
- A.Nothing, any amount under 0.04 is acceptable
- B.The driver is placed out of service for 24 hours
- C.The driver loses the CDL permanently on the spot
- D.Only a written warning is issued
Correct answer
B. The driver is placed out of service for 24 hours
Why
Even below the 0.04 legal limit, any measurable alcohol in your system removes you from a safety-sensitive function for 24 hours. Alcohol and commercial driving simply do not mix at any level.
