What Happens If You Let Your DOT Medical Card Expire?

July 19, 2025

For commercial drivers, maintaining a valid DOT medical card is not optional—it’s a federal requirement. If your DOT medical card expires, the consequences can be serious, affecting your ability to legally operate a commercial motor vehicle (CMV), retain your CDL, and keep your job.

In this blog, we’ll break down what happens when your DOT medical certificate expires, how it can impact your career, and what steps you need to take to regain compliance.

Why the DOT Medical Card Matters

The DOT medical exam, mandated by the Federal Motor Carrier Safety Administration (FMCSA), is designed to ensure that commercial drivers are physically and mentally fit to safely operate CMVs. Once you pass the exam, you’re issued a Medical Examiner’s Certificate (MEC), often referred to as the DOT medical card. This certification is typically valid for up to two years, although drivers with certain health conditions may receive shorter-term cards.

The FMCSA requires all commercial drivers to keep a valid and current medical card on file with their state’s Department of Motor Vehicles (DMV) or licensing agency.

What Happens When Your DOT Medical Card Expires?

Letting your DOT medical card expire can have several consequences, including:

1. You Are No Longer Authorized to Drive a CMV

As soon as your DOT medical card expires, you are no longer legally allowed to operate a commercial vehicle. Continuing to drive without a valid medical certificate puts you in direct violation of FMCSA regulations.

2. Your CDL May Be Downgraded

If your state’s DMV doesn’t receive updated medical certification by the required deadline, they may automatically downgrade your CDL to a non-commercial license. This process varies by state, but many jurisdictions allow as little as 30 days before taking this action.

3. You Risk Losing Employment

Most employers require drivers to keep their DOT certifications current. An expired card could result in temporary suspension, missed work, or even termination depending on company policy and the time it takes to get re-certified.

4. You Could Face Fines and Legal Penalties

Driving with an expired DOT medical card can result in fines, citations, or liability issues in the event of an accident or inspection. These violations can also affect your driving record and compliance history.

How Long Do You Have Before Your CDL Is Downgraded?

Each state sets its own rules regarding how long a driver has to submit their updated DOT medical card. For example:

  • Some states require submission prior to the expiration date.
  • Others allow a grace period of 30 to 60 days before initiating a downgrade.
  • In some cases, failure to submit in time may require you to retake CDL knowledge and skills tests.

Check with your state’s licensing office to confirm the exact timeline.

How to Fix an Expired DOT Medical Card

If your card has expired, follow these steps as soon as possible:

1. Schedule a DOT Physical Exam

Book an appointment with a certified medical examiner listed in the National Registry of Certified Medical Examiners. If you have a pre-existing medical condition, bring any required documents or test results.

2. Obtain Your New Medical Certificate

If you pass the exam, your provider will give you a new DOT medical card. Be sure to keep both a physical and digital copy.

3. Submit It to Your State DMV

Most states allow you to submit your updated card:

  • In person
  • By fax or email
  • Through an online DMV portal

Submit the certificate immediately after receiving it to avoid penalties or license downgrades.

4. Confirm Receipt and Compliance

Contact your DMV to confirm that your updated medical card was processed and that your CDL status is in good standing.

How to Avoid Letting Your DOT Card Expire

Avoiding expiration is simple with a little planning:

  • Know your expiration date: It’s printed on your DOT medical certificate.
  • Set a reminder: Schedule a renewal exam at least 30 to 60 days before your card expires.
  • Keep copies: Always retain proof of submission to the DMV.
  • Update your employer: Make sure your employer is aware of your medical certification status.

Final Thoughts

Letting your DOT medical card expire can have serious consequences for your license, livelihood, and legal standing as a commercial driver. The good news is that it’s easy to avoid expiration with early planning and timely submission.

If your card is nearing expiration—or has already expired—take immediate action. The sooner you complete your renewal and submit your documentation, the sooner you can get back on the road legally and safely.
