Introduction

A DOT medical card is a certification required for commercial drivers in the United States. If you operate a commercial motor vehicle (CMV), you must prove that you are physically and medically qualified to drive safely. The Department of Transportation (DOT), under the Federal Motor Carrier Safety Administration (FMCSA), sets these medical standards.

In 2026, DOT medical card requirements remain essential for CDL holders and certain non-CDL commercial drivers. Without a valid medical certificate, your commercial driving privileges can be suspended. Understanding the process helps you avoid delays and stay compliant.

What Is a DOT Medical Card?

A DOT medical card, officially called a Medical Examiner’s Certificate (Form MCSA-5876), confirms that a driver meets federal health requirements. It is issued after passing a DOT physical exam conducted by a certified medical examiner listed in the FMCSA National Registry.

The card verifies that you do not have medical conditions that could interfere with safe driving. This includes vision problems, uncontrolled diabetes, high blood pressure, heart conditions, and sleep apnea.

Who Needs a DOT Medical Card?

Most interstate commercial drivers operating vehicles over 10,000 pounds require a DOT medical card. This includes truck drivers, bus drivers, and some delivery drivers. CDL holders transporting hazardous materials or passengers also need valid certification.

Intrastate requirements vary by state, but many follow federal FMCSA medical standards. Always check with your state’s Department of Motor Vehicles (DMV) for specific rules.

What Happens During a DOT Physical?

The DOT physical exam checks overall health and ability to operate a commercial vehicle safely. The medical examiner reviews your medical history and performs several standard tests.

If you pass, you receive a DOT medical certificate valid for up to 24 months. Drivers with certain medical conditions may receive shorter certifications, such as 3, 6, or 12 months.

DOT Medical Card Cost in 2026

The cost of a DOT physical exam varies depending on the clinic and state. In 2026, the average cost ranges between $75 and $150. Some employers cover this expense for their drivers.

Additional testing for conditions like sleep apnea or diabetes may increase costs. Always verify pricing before scheduling your exam.

How Long Is a DOT Medical Card Valid?

A standard DOT medical card is valid for up to 24 months. However, drivers with controlled medical conditions may receive shorter-term certifications to ensure ongoing monitoring.

Renewal should be completed before expiration to avoid CDL downgrade or suspension. Many states now electronically link medical certificates to DMV records.

Common Medical Disqualifications

Certain medical conditions may disqualify drivers if not properly managed. These include uncontrolled high blood pressure, insulin-treated diabetes without proper documentation, severe heart disease, epilepsy, or untreated sleep apnea.

However, waivers and exemptions may be available in some cases. The FMCSA provides guidance for drivers with stable medical conditions.

How to Prepare for Your DOT Physical

Preparation can increase your chances of passing the exam. Bring a list of medications, medical records, and contact lenses or hearing aids if used.

Conclusion

A DOT medical card is essential for commercial drivers in the United States. It ensures drivers meet health standards required for safe road operation. Staying compliant protects your CDL status and career.

By understanding requirements, costs, and renewal timelines, you can maintain your certification without interruption. Always schedule your renewal before expiration and consult certified medical examiners listed by the FMCSA.
