Renewing Your CDL in Montana

Don’t risk waiting too long to get your commercial driver’s license (CDL) renewed. The Montana Motor Vehicle Division (MVD) has a few different options for renewing your CDL so read on to find the best option for you.

How to Renew a CDL in Montana

Commercial driver’s licenses need to be renewed every 4 years for drivers between the ages of 21 and 70 years old.*

In Montana, you can either renew your commercial driver’s license:

  • By mail.
  • In person.

You are able to renew your commercial driver’s license up to 6 months before it expires.

Once your license does expire, you still have 12 month to renew it before you will need to reapply and take the tests again. However, your CDL will not be valid until it is renewed.

* If you are not within this age range, you can take a look at the Montana MVD CDL guide to see how often you will need to renew based on your age.

By Mail

You can renew your MT commercial driver’s license by mail if you are:

  • A Montana resident who is currently out of town and does not plan on being back before the expiration date.
  • Living in a county that does not offer driver’s license services.
  • NOT renewing a commercial driver license with a HAZMAT endorsement on it*.

Once you verify that you qualify to renew by mail, make sure to have your:

Send the above items in an envelope to:

Motor Vehicle Division
P.O. Box 2014340
Helena, MT 59620

*NOTE: If you have a HAZMAT endorsement on your CDL, you CANNOT renew through mail unless you are planning on dropping it. To retain your HAZMAT endorsement, you MUST renew in person.

In Person

You need to renew your MT commercial driver license in person if you:

  • Have a HAZMAT endorsement.
  • Plan to renew through a full-service driver’s license exam station.

To renew your license at a rural, limited-service driver’s license exam station, you must:*

You’ll then take the receipt with you to your renewal appointment at the limited-service exam station.

If you reside in a county that does not offer driver’s license services, you can renew by:

  • Going to a full-service driver’s license exam station.
  • Going to a limited service exam station.
  • Mail—but the next time you renew, it will need to be in person.

*You may need to bring documents proving your name, address, and/or Social Security number. To find out exactly what you need to bring, give your county treasurer’s office a call.

Medical Requirements for a MT CDL

As a commercial driver, it’s important that you keep your Medical Examiner’s Certificate (Form MCSA-5876) current to avoid being downgraded to a standard driver’s license. The MVD has an online portal to check the status of your MEC.

You must submit a copy of your updated MEC to the Montana MVD before your current certificate expires.

You can mail your MEC to the address below:

Motor Vehicle Division
Attn: CDL Help Desk
P.O. Box 201430
Helena MT 59620

All physicals must be done by a medical professional from the National Registry of Certified Medical Examiners. See our page on applying for a Montana CDL for more details on medical certification.

MT CDL Renewal Fees

The fees for renewing your Montana CDL vary and are based on:

  • Endorsements.
