How Truck Drivers Can Renew Their DOT Medical Card in 2025

If you drive commercial trucks or manage a fleet, you already know how important your DOT medical card is. Without it, you can’t legally operate a commercial vehicle, and your CDL could be suspended. 

Renewing your DOT medical card on time is essential for staying on the road and avoiding costly interruptions. We’ll walk through everything truckers and fleet managers need to know about renewing DOT medical cards in 2025. 

Why DOT Medical Card Renewal Matters

DOT medical cards prove you meet the physical and mental requirements to safely operate commercial vehicles. The Federal Motor Carrier Safety Administration (FMCSA) sets strict expiration dates based on your health and exam results. When your medical card expires, so does your legal authority to drive.

Missing renewal deadlines can lead to your CDL being flagged or suspended, causing fines and lost income. For fleets, drivers without valid medical cards create operational challenges. Knowing when and how to renew your card ahead of time is the best way to avoid these problems.

How Long Is a DOT Medical Card Valid?

The validity of your DOT medical card depends on the health information you provide during your exam. Most cards last for 24 months, but if you have certain medical conditions like high blood pressure or diabetes, your card may be valid for 12 months or less.

Starting in 2025, the FMCSA continues to enforce these timelines closely. You will receive an expiration date on your card that indicates exactly when you must renew. 

It’s your responsibility to keep track of this date and schedule your next physical in advance.

When Should You Schedule Your DOT Physical Renewal?

Scheduling your DOT physical before your medical card expires is crucial. A good rule of thumb is to book your renewal exam at least 30 days before the expiration date. This allows time for paperwork processing and avoids gaps in your certification.

Waiting until the last minute risks delays from medical examiners or processing backlogs. If your card expires, you won’t be allowed to drive commercially until you pass a new DOT physical and get a new card.

What to Expect During Your DOT Physical Renewal in 2025

The DOT physical exam continues to focus on important health areas such as vision, hearing, blood pressure, heart health, and diabetes management. Medical examiners will review your medical history and may ask about sleep apnea or medication use.

Certified medical examiners approved by the FMCSA conduct these exams. In 2025, be sure to visit an examiner listed in the National Registry of Certified Medical Examiners to ensure your exam is valid.

While there is no new FMCSA requirement to bring recent lab results for diabetes or hypertension starting June 23, 2025, drivers with controlled diabetes, especially those using insulin, are generally expected to provide glucose logs or other documentation as part of their ongoing management. Similarly, blood pressure must be controlled and documented during your exam.

Bringing any relevant medical documentation or treatment records will help your examiner evaluate your fitness to drive and determine the appropriate certification length.

Without these documents, your examiner may issue only a temporary certification or deny your medical card renewal. If you have any ongoing medical conditions, bring supporting documentation or treatment records. This helps the examiner evaluate your fitness to drive and issue the correct medical card duration.

How to Renew Your DOT Medical Card: Step-by-Step

Renewing your DOT medical card in 2025 is easier than you might think. Taking care of it early means less stress and no surprises that could keep you off the road. Whether you drive solo or manage a fleet, knowing the steps ahead makes everything smoother.

1. Find a certified medical examiner near you using the FMCSA National Registry website.

2. Schedule and attend your DOT physical exam.

3. Complete the medical history questionnaire honestly and provide any requested documents.

4. Pass the exam and receive your medical card with the new expiration date.

5. Keep a copy of your card in your vehicle and provide a copy to your employer or fleet manager.

6. Update your medical certification information with your state’s Department of Motor Vehicles (DMV) or licensing authority if required.

What Happens if You Miss Your DOT Medical Card Renewal?

If your medical card expires, you lose your legal right to operate a commercial vehicle. This means no driving for work until you complete a new physical and get recertified, which leads to lost income and possible fines.

For fleet managers, having drivers with expired medical cards can result in compliance violations during inspections. This is not only a personal issue but also affects your entire operation.

If your medical card has expired, schedule a DOT physical exam immediately to avoid further downtime. Driving without a valid card is illegal and puts you at risk of penalties.
