On March 6, 2019 (84 FR 8029 ) the Federal Motor Carrier Safety Administration (FMCSA) amended the entry-level driver training (ELDT) regulations published on December 8, 2016, titled “Minimum Training Requirements for Entry-Level Commercial Motor Vehicle Operators” (ELDT final rule), by adopting a new Class A CDL theory instruction upgrade curriculum to reduce the training time and costs incurred by Class B commercial driver's license (CDL) holders upgrading to a Class A CDL. This final rule does not change the regulatory text proposed in the Notice of Proposed Rulemaking (NPRM). The Agency believes that this modest change in the Class A theory training requirements for Class B CDL holders upgrading to a Class A CDL maintains the same level of safety established by the ELDT final rule, and the regulatory burden reduction will result in annualized cost savings of $18 million. This final rule is effective May 6, 2019. The compliance date for this final rule is February 7, 2020. Petitions for Reconsideration of this final rule must be submitted to the FMCSA Administrator no later than April 5, 2019.
