CDL disqualifications: Conviction in court of driving any motor vehicle under the influence of alcohol or drugs
How long will my license be disqualified?
First incident: 1 year (3 years if the incident occurred while you were transporting hazardous materials.)
Second incident or more: For life
Entering into a deferred prosecution program is considered a DUI conviction for commercial driver license (CDL) disqualification purposes.
How to re-qualify
Pass the CDL knowledge and skills tests.
For a hazardous materials endorsement, pass a separate knowledge test. (We also may require you to show us a letter from the Transportation Security Administration stating you passed their background check.)
Pay a $35 re-qualification fee.
Second incident or more: You cannot re-qualify after a lifetime disqualification.
