There are many different reasons why a commercial driver’s license (CDL) could be suspended or revoked. One common reason is receiving a DUI. This happens whether you are operating your personal vehicle or a commercial motor vehicle at the time of the charge. Once a driver has received a DUI and their license gets revoked, they can’t operate a commercial motor vehicle. Tickets or convictions from out of state also hold reciprocity in the state of Connecticut. They are reported to the Department of Motor Vehicles and then transferred to your Connecticut driver’s license.


If one of these offenses occurs in conjunction with driving a vehicle that is transporting hazardous materials, the minimum disqualification will be for three years. If convicted twice for either driving under the influence or refusal or failure of a BAC test, the result would be a lifetime disqualification of your commercial driver license. A first offense of using a commercial vehicle while under the influence of a controlled substance will also result in a lifetime disqualification.

Disqualification will result from a conviction of any one of the following:

  • Operation under the influence of alcohol.
  • Refusal to take a blood, breath or urine test.
  • Failure of a blood, breath or urine test (0.04 or greater).
  • Evading the police.
  • Use of a commercial vehicle in conjunction with a felony conviction.

If your livelihood depends on your CDL license, you want to avoid a DUI conviction at all costs. If your license is revoked, you will be unable to work for a certain amount of time. Keep in mind that refusing to take a blood, breath, or urine test is not in your best interest, as this will automatically trigger the disqualification of your license.
