DOT Medical Cards: Tracking Expirations Before They Become Violations

A driver with an expired medical card is not qualified to drive a commercial motor vehicle. It does not matter how safe they are or how long they have driven. It is one of the simplest violations to find and one of the easiest to prevent, yet it keeps showing up in audits and roadside inspections.

Here is what the rules require and how to stay ahead of expiration dates.

The basic requirements

Under 49 CFR 391.41, a person may not drive a CMV unless they are physically qualified and have a current medical examiner’s certificate. Key points:

• Who can examine: The physical must be performed by a medical examiner listed on FMCSA’s National Registry of Certified Medical Examiners (49 CFR 391.43).
• How often: Under 49 CFR 391.45, drivers must be examined and certified at least every 24 months.
• Shorter certificates: The examiner can issue a certificate for less than 24 months when a condition needs closer monitoring. High blood pressure and insulin-treated diabetes are common examples. A one-year card is not unusual.
• Other triggers: A driver whose ability to perform normal duties has been impaired by a physical or mental injury or disease must be re-examined, even if their card has not expired.

Some drivers operate under a medical exemption or variance, such as a vision standard alternative. These have their own rules and time limits. Track them just as carefully.

What goes in the driver qualification file

Under 49 CFR 391.51, the carrier must keep:

• The medical examiner’s certificate, or a copy of it.
• A note verifying the medical examiner was listed on the National Registry at the time of the exam.
• Any medical variance or exemption documents that apply.

For CDL holders, medical certification also has to reach the state driver licensing agency, and the state records the driver’s medical status. Carriers generally need proof of that status from the driver’s state record in the file. FMCSA has been changing how medical exam information moves from examiners to states, so check current guidance on what to keep for CDL drivers.

Medical certificates and the related notes may be removed from the file three years after they were executed.

What happens when a card expires

The consequences come from several directions:

• The driver is not qualified. Using that driver is a violation, and in a compliance review, using a driver who is not medically certified is a serious finding that can affect your rating.
• Roadside violations. An inspector who finds an expired medical certificate can cite the driver, and the violation counts in your safety data.
• CDL downgrade. For CDL holders, if the state does not receive current medical information, the state can downgrade the driver’s license. A driver may not even know until the license is already downgraded.
• Insurance and liability. After a crash, an expired medical card is a problem nobody wants to explain.

Why tracking breaks down

Most carriers do not ignore medical cards on purpose. They lose track. Common reasons:

• Drivers are on different expiration schedules, so dates are scattered across the year.
• Short-term certificates, like one-year or three-month cards, catch people off guard.
• The office relies on drivers to bring in new cards.
• The new card is filed, but the National Registry verification note is not.
• For CDL drivers, nobody checks that the state record updated.

A spreadsheet can work for a small fleet if someone checks it every week. The problem is that spreadsheets do not send reminders.

A better tracking process

Build a simple system that works even on busy weeks.

1. Record every expiration date as soon as a new card comes in.
2. Set reminders well ahead of each date. Many carriers use 90, 60 and 30 days.
3. Tell the driver early and help schedule the exam around their route.
4. Verify the examiner on the National Registry and document it.
5. Check the state record for CDL drivers after the new certification.
6. Pull the driver from driving if the card expires before a new one is in hand.
7. Review your whole roster monthly for anything due in the next 90 days.

DOT Compliance Watch does the reminder step for you. It sends alerts before medical cards expire, alongside CDLs, annual reviews and other dates, so the whole team sees what is coming.

Quick medical card checklist

For each driver:

• Is there a current medical certificate on file?
• Is the expiration date recorded and tracked?
• Is there a note verifying the examiner on the National Registry?
• Are any exemptions or variances current and on file?
• For CDL drivers, does the state record show current medical status?

Medical rules can involve judgment calls on conditions and exemptions. For those, talk to a certified medical examiner or FMCSA. You can find more in our FAQ.

Stop chasing expiration dates

Medical card violations are almost entirely preventable. What they take is a system that reminds you in time. Compare plans and let automatic alerts do the remembering.
