Replacing a Lost CDL in Connecticut

The Connecticut Department of Motor Vehicles (DMV) won't issue a replacement commercial driver's license by mail; if you're in state, you must apply in person at your local DMV office. However, if you're out of state, you can voluntarily surrender or downgrade your CDL by mail.

Because it's illegal to drive a commercial vehicle without a CDL, it's important you apply for a replacement as soon as possible. Also, be sure to report your lost CDL to local and state authorities to help fight identity theft.

Out-of-State CT Driver with Lost CDL

If you're currently out of state and lose your CDL, contact the CT DMV for replacement instructions.

You MIGHT be allowed to order a duplicate CDL by mail, or you MIGHT have to wait until you can visit a CT DMV office in person (as is the case for CDL renewals). The CT DMV will explain your options based on your situation.

Regardless of how you're able to order your replacement CDL, remember that while you're out of state:

  • It's illegal to operate your commercial truck without your valid CDL on you.
  • An identity thief could get hold of your lost CDL, so it's wise to report it to the local and state authorities—both in Connecticut and the state you're currently in.
