Missouri CDL Requirements

All Missouri CDL holders are required to certify the type of commercial operation they’re engaged in.

Interstate Non-Excepted
You must meet the Federal DOT medical certificate requirements.

Intrastate Non-Excepted
You must meet the Federal DOT medical certificate requirements.


Under the federal regulations, all CDL holders must make the certification of category and any required medical certificate by January 30, 2014. To help avoid a rush at the license offices, the Department will be notifying current CDL holders by postcard asking them to go into a license office and certify within 60 days from the date on the postcard. Please avoid waiting until the last minute as all CDL holders in Missouri are subject to this federal regulation.


Submitting your Medical Certificate to Missouri License Office

When requested, submit a copy of your valid DOT medical certificate.

CDL Medical Certification Requirements

Special Information Updates  – JANUARY 2015 –
Pertaining To ALL STATES


The FMCSA has requested that all medical examiners continue providing drivers with a paper copy of the medical certificate so that Commercial Driver’s License (CDL) holders can provide a copy to the State licensing agency, and the non-CDL drivers can provide the documentation to their employers and Federal and State enforcement officials.

The Agency is currently completing efforts to put into place an electronic system to enable medical examiners to transmit the medical certificate information from the National Registry system to the State licensing agencies. However, until that system is completed, medical examiners must continue to issue paper copies of the medical certificates to drivers who pass the medical exam.


Commercial Drivers – You still need to carry a paper copy of your medical card, until FMCSA announces that this is no longer necessary.

    If a person was to let their dot medical certificate expire will they lose their cdl license if they aren’t driving for anyone at that time that requires a cdl.

    If my cdl drivers license is from missouri and I’m living in another state. How can I update my new medical card? Thanks

    • says

      A DOT medical card is valid nationwide so you can get your medical card in any state, no matter which state you have your CDL.
      Make sure you send a copy of your new medical card to Missouri License Office to update your CDL record.
      For more information see FAQ – FMCSA.

    When a CDL driver is grandfathered for an intrastate medical certificate, what action must he do to meet the current regulations. Must he certify with the Department of Revenue to be Excepted Intrastate or Intrastate Non-Excepted? Must he have a variance document and if so what form would be used.
