This legislation directs the Secretary of Transportation, through the Federal Motor Carrier Safety Administration, to revise specific regulations related to Commercial Driver's License (CDL) testing within 90 days of enactment. One key modification will allow a State or third-party examiner to administer a CDL knowledge test, provided the examiner holds a valid certification and has completed required skills test examiner training and specific instructional units. The bill also mandates a revision to permit any State to administer a CDL driving skills test to an applicant. This provision removes restrictions based on the applicant's state of domicile or where they received their driver training, aiming to streamline the testing process for commercial drivers.
