The Missouri State Highway Patrol and Missouri Department of Revenue wish to inform the public there has been a change to the commercial driver license testing procedure.

Commercial driver license (CDL) applicants need to be aware Missouri is adopting a modernized testing standard effective December 4, 2023. CDL examiners at all Patrol examination sites and all third-party examination sites will utilize the new testing procedure. The changes in testing procedure include a more streamlined pre-trip examination and more efficient basic skills course. Those wishing to prepare for a CDL skills test administered December 4 or later should utilize the following CDL manual to learn applicable procedures: New Missouri CDL Manual. The current testing procedures will remain in effect statewide until December 1.

Per federal guidelines, applicants must pass the pre-trip and basic skills using the same testing model. Thus, if an applicant passes the pre-trip examination under the previous CDL testing procedure, they must pass the basic skills test using that same testing procedure to be eligible for the road test.
