The Medical Examiner’s Certificate (MEC), also known as the DOT Medical Card, is a document that certifies a commercial driver’s physical qualification to operate a commercial motor vehicle (CMV) in interstate commerce. This certification is mandated by the Federal Motor Carrier Safety Administration (FMCSA) to ensure the safety of both the driver and the public.
Validity of the MEC
- Standard Validity: The MEC is typically valid for up to 24 months (2 years).
- Shorter Validity Periods: If a driver has certain medical conditions (e.g., hypertension, diabetes, sleep apnea), the medical examiner may issue a certificate valid for less than 2 years to monitor the condition more closely.
Updating the MEC with State DOTs
To maintain a valid CDL, drivers must ensure their MEC is current and submitted to their respective State Driver Licensing Agency (SDLA).
General Steps:
- Obtain a New MEC: Visit a certified medical examiner listed on the National Registry of Certified Medical Examiners to complete a new physical examination and obtain the MEC (Form MCSA-5876).
- Submit to SDLA: Provide the updated MEC to your state’s DOT through the available submission methods (online, mail, fax, or in-person).
- Timely Submission: Submit the new MEC before the current one expires to avoid CDL disqualification or downgrade
