Which situation would lead to a loss of your CDL for one year?

Speeding
Higher than .04% BAC while driving a CMV
Not wearing a seatbelt
Failing an inspection

The correct answer is: Higher than .04% BAC while driving a CMV

The situation leading to a loss of your Commercial Driver’s License (CDL) for one year is being found with a blood alcohol concentration (BAC) greater than .04% while operating a Commercial Motor Vehicle (CMV). Commercial drivers are held to a stricter standard regarding alcohol consumption due to the risks involved in driving large vehicles that can cause substantial harm in the event of an accident. A BAC above this threshold indicates impaired driving ability, which is taken very seriously in the transportation industry. This regulation is designed to promote safety both for the driver and for everyone else on the road. Penalties for violating this rule are severe because they aim to deter such behavior and ensure that commercial drivers maintain a high standard of responsibility. While situations like speeding, not wearing a seatbelt, or failing an inspection may lead to penalties or fines, they do not carry the same level of consequence regarding the immediate loss of a CDL.
