CDL Testing

  • CDL written knowledge testing may be completed at any Missouri State Highway Patrol Driver Examination Station. Pursuant to §302.720.2(1) RSMo., the written testing shall only be administered in English and no translators shall be allowed for applicants taking the knowledge test. The Missouri Commercial Driver License Manual is available online, in any MSHP Driver Examination office, or any Missouri license office.
  • CDL skills testing is available to the public by appointment only at defined Missouri State Highway Patrol CDL Test Sites. CDL skills test applicants must have completed applicable knowledge testing and have held a Commercial Learner’s Permit (CLP) a minimum of 14 days prior to skills testing.
  • Reasonable testing accommodations for CDL applicants with disabilities, including persons who are deaf or hard of hearing, will be made in accordance with current State and Federal guidelines. Applicants may request consideration of accommodation by contacting the Missouri State Highway Patrol Driver and Vehicle Safety Division at 573-751-2341.
  • Applicants that wish to operate in a non-exempted interstate or non-exempted intrastate commerce are required to obtain a DOT Medical Examiner's Certificate prior to the issuance of a CLP or CDL. Drivers with physical impairments that may affect their ability to safely operate a CMV, must obtain a “variance” form issued through the Missouri Department of Transportation (MODOT) or the Federal Motor Carrier Safety Administration (FMCSA). For example, such “variance”, often a Skill Performance Evaluation (SPE), is required for drivers with impaired or missing limbs, and must be carried with the Medical Examiner's Certificate at all times.
