Medical Requirements for CDL Holders in D.C.

Commercial drivers in Washington, D.C. are subject to specific medical standards to ensure the safety of all road users. The District of Columbia Department of Motor Vehicles (DC DMV), in coordination with the Federal Motor Carrier Safety Administration (FMCSA), mandates that CDL holders meet and maintain certain physical qualifications. Here’s what every commercial driver in D.C. needs to know about medical certification and related compliance requirements.

Who Needs a Medical Certificate?

All CDL applicants and holders who drive or intend to drive a commercial motor vehicle (CMV) in interstate commerce must have a valid Medical Examiner’s Certificate (Form MCSA-5876). This includes:

• Class A, B, and C license holders operating vehicles over 10,000 pounds
• Those transporting hazardous materials requiring placards
• Drivers of passenger vehicles designed to transport 16 or more people

Medical Examination and Certification

To be medically certified, drivers must undergo a Department of Transportation (DOT) physical exam conducted by a medical examiner listed on the National Registry of Certified Medical Examiners. The exam checks for a range of conditions that could impair safe driving, including:

• Vision and hearing
• Blood pressure and cardiovascular health
• Respiratory conditions
• Diabetes requiring insulin
• Neurological conditions such as epilepsy
• Mental health history and substance abuse

If the driver meets all criteria, the examiner issues a Medical Examiner’s Certificate valid for up to 24 months. In some cases, certification may be issued for a shorter period based on a condition requiring monitoring.

Self-Certification Categories

Drivers must self-certify their type of driving with the DC DMV. The four categories are:

1. Interstate Non-Excepted: Requires medical certification
2. Interstate Excepted: Medical certification not required
3. Intrastate Non-Excepted: Requires medical certification
4. Intrastate Excepted: Medical certification not required

Most CDL holders fall into the Interstate Non-Excepted category.

Submitting Medical Certificates to the DC DMV

Once certified, CDL holders must submit their Medical Examiner’s Certificate to the DC DMV:

• Online through the DC DMV CDL Medical Certification Portal
• In-person at a DC DMV service center
• By mail or fax, if preferred

The DMV recommends retaining a copy of both the certificate and the long-form medical exam report.

Consequences of Non-Compliance

Failure to maintain or submit a valid medical certificate can result in:

• Downgrade of your CDL to a non-commercial license
• Disqualification from operating a CMV
• Possible fines and removal from duty

It’s essential to keep track of expiration dates and renew the certificate in a timely manner.

Special Cases: Waivers and Exemptions

Some drivers with disqualifying medical conditions may apply for exemptions or waivers through FMCSA:

• Vision exemption for drivers with monocular vision
• Diabetes exemption for insulin-treated diabetes mellitus
• Skill Performance Evaluation (SPE) for limb impairments

These applications involve additional documentation and, often, specialist evaluations.
