On July 9, 2019, CVSA submitted a petition to the Federal Motor Carrier Safety Administration (FMCSA) requesting that the agency amend Title 49 Code of Federal Regulations § 389.603, Training for supervisors, to require controlled substances training for company supervisors be recurrent every three years. Given the increased levels of drug impaired driving, recurrent training would insure that supervisors have up-to-date training on recognizing controlled substance use.
