CDL DOT Medical
It is an exam that indicates an individual is physically qualified to operate a commercial motor vehicle in accordance with 49 CFR 391.41, Subpart E - Physical Qualifications and Examinations.
You are no longer medically qualified to operate a commercial vehicle and your CDL is subject to cancellation. You must keep your DOT medical up-to-date (new exam a minimum of every two years based on the previous exam’s expiration date). If you do not have a current DOT medical, you will be required to downgrade your CDL to a regular license.
All DOT medical information is submitted directly to FMCSA’s National Registry “Registry” by the medical provider. The State of Colorado will receive that information electronically from the registry. This is the only allowable method of receiving Certified Medical Examiner Certificates.
The medical provider will submit the information to the Registry within 24 business hours of the medical exam. If you have recently seen a provider, please wait 24-48 business hours, then you can confirm the information is posted at mydmv.colorado.gov or by calling our customer service call center at 303-205-5613. If the medical information has not been updated, please contact your medical professional.
