Colorado CDL Practice Test

Under what condition can you receive a 24-hour suspension while operating a CMV?

1. If your BAC is 0.00%

2. If your BAC is 0.02%

3. If your BAC is between .00000001 to .04%

4. If your BAC is over 0.08%

The correct answer is: If your BAC is between .00000001 to .04%

The correct condition for receiving a 24-hour suspension while operating a Commercial Motor Vehicle (CMV) is when your Blood Alcohol Concentration (BAC) falls between .00000001 to .04%. Operating a CMV with any detectable amount of alcohol indicates impairment, and the regulations in place are strict to maintain safety on the roads. A BAC within this range suggests that there are trace amounts of alcohol present, even if not enough to be considered legally intoxicated under personal vehicle operation laws. However, for commercial drivers, the standards hold them to a higher level of sobriety due to the increased responsibility they carry when operating larger vehicles. This regulation is in place to ensure that commercial drivers are fully alert and can safely handle their vehicle, protecting both themselves and others on the road. The other options do not align with the legal BAC thresholds for commercial drivers. A BAC of 0.00% would not warrant a suspension, nor would a BAC of 0.02% in most contexts, as it doesn't cross into the threshold that necessitates a suspension. A BAC over 0.08% is generally recognized as a legal limit for driving under the influence for non-commercial operators, which is a higher threshold than the one associated with a
