Renewing Your CDL in Wyoming

How to Renew

In Wyoming, you cannot renew a commercial driver license (CDL) with a HAZMAT endorsement through the mail. You must appear in person to take the endorsement tests. CDL without a HAZMAT endorsement may be renewed through the mail. Before your CDL expiration date, you should receive a renewal notice.

It is imperative that you keep the agency updated on any changes of address so the renewal document manages to find you in the place you currently inhabit.

Where to Send the Renewal Form

Once you complete the renewal form, you will need to dispatch it back to the division along with a copy of your current DOT medical certificate and a renewal fee. Mail all documents to:

  • Driver Services
  • 5300 Bishop Blvd
  • Cheyenne, WY 82009

Note that renewal by post is only offered every other cycle; thus, once every 8 years.

Renewing Hazardous Material Endorsements

If you are renewing a hazardous materials (hazmat) endorsement the service is not available by mail. You will still need the DOT Medical Examination Report (Form 649-F), but you will also need your "threat potential" assessed by the Transportation Safety Administration (TAS). The requirements involve a trip to a local TSA office for fingerprinting.

Information for the background check can be submitted online through the TSA website or by calling the TSA Help Desk at (855) 347-8371. A fee is charged for the service, payable via e-check, credit or debit card. If those means of payment are not viable, you can take a money order made out to one of the TSA offices when you go for fingerprinting.

Identification, a primary and a secondary form, as noted on the approved TSA list , are necessary to have the prints taken and verified.

TSA will notify you by letter regarding the results of the background check. If you are in the clear, then the next step involved is gathering all the documents necessary to extend the CDL (the letter from TSA, DOT medical exam, and renewal card) and visiting the nearest exam office.

The renewal cost is for a CDL is $40. You will need to add $11 if you have a motorcycle endorsement.
