DOT Medical Certificates

Who needs a DOT medical card, how to get one, and what happens when it expires.

A DOT Medical Certificate (Form MCSA-5876) is required for every commercial driver operating vehicles above the FMCSA weight threshold. It proves that the driver meets the physical health standards set by 49 CFR Part 391. Keeping these certificates current is one of the most frequently cited violations during DOT compliance reviews.

Who Needs a DOT Medical Card?

Any driver operating a commercial motor vehicle (CMV) in interstate commerce that weighs more than 10,001 lbs, carries 9 or more passengers for compensation, or transports hazardous materials must hold a valid DOT medical certificate. This applies to owner-operators as well as employed drivers. The rule covers both CDL and non-CDL drivers in many cases.

The Medical Exam Process

Drivers must be examined by a licensed medical examiner listed on the FMCSA National Registry. The exam covers vision, hearing, blood pressure, cardiovascular health, and neurological function. Examiners look for conditions that could impair safe driving — such as sleep apnea, diabetes requiring insulin, or certain vision disorders. The exam typically takes 30–60 minutes and costs $75–$150 depending on the provider.

Certificate Validity and Renewal

Most medical certificates are valid for up to 24 months. Drivers with certain health conditions — such as controlled hypertension or insulin-treated diabetes with an exemption — may receive shorter validity periods of 3, 6, or 12 months. CDL holders must keep a copy of their current medical certificate and submit it to their state DMV within 7 days of issuance. BridgeWorks One™ tracks expiration dates and sends alerts before renewals come due.

Consequences of an Expired Certificate

Operating with an expired DOT medical certificate is a serious violation. The driver is immediately placed out-of-service until a valid certificate is obtained, and the carrier receives a violation on their safety record. Multiple violations can trigger a DOT compliance review or adversely affect your CSA score under the Driver Fitness BASIC. Fines can reach $16,000 per violation for knowing violations.
