1. (1) The director authorizes the Missouri State Highway Patrol to administer skills tests to commercial motor vehicle operator applicants in accordance with the laws of this state.
2. (2) Any person requiring a commercial driver license who must successfully complete the skills tests shall pass a pretrip inspection, off-road basic controls test and on-road driving test.

3. (3) The person shall complete three (3) skills tests, unless otherwise specified here, for a Class A, Class B, or Class C commercial driver license.

   1. (A) Except for Class C drivers, the pre-trip inspection shall be required for any vehicle equipped with airbrakes and only those vehicles with a manufacturer’s Gross Vehicle Weight Rating (GVWR) of ten thousand one pounds (10,001 lbs.) or more. A pre-trip inspection shall include standardized inspection items as defined in the Missouri Commercial Driver License Manual section 11M, Vehicle Inspection.
   2. (B) An off-road basic controls test shall include but not be limited to testing of the current standardized maneuvers listed in the Missouri Commercial Driver License Manual, section 12M, Basic Control Skills Test.
   3. (C) An on-road driving test shall include but not be limited to a demonstration of skills defined in the Missouri Commercial Driver License Manual, section 13M, On-Road Driving.
4. (4) Successful completion of all the test’s mandatory components requires a score as shown on the Commercial Driver License
5. (CDL) and disallows dangerous actions and traffic violations during the off-road basic controls, on-road driving tests, or both.
6. (5) Test scores shall be submitted to the Department of Revenue through a secure electronic means. The test scores remain valid unless retesting is required by Missouri law or one (1) year from the date indicated on the examination results, whichever occurs first. Each person shall be responsible for maintaining a copy of the test results. If test results cannot be provided by the driver at the time of application for a Missouri commercial driver license, the application may be denied; or the applicant shall be required to retake any tests necessary to receive the class of license and endorsements requested.
7. (6) The director shall provide all forms necessary to administer driving tests to the Missouri State Highway Patrol.
