FMCSA Tightens CDL Revocations for Drug & Alcohol Violations

On Oct. 7, the Federal Motor Carrier Safety Administration published its final rule prohibiting state driver licensing agencies from issuing a CDL to any individual prohibited from performing safety-sensitive functions because of one or more violations in the Drug and Alcohol Clearinghouse. The rule, effective Nov. 8, also requires that licensing agencies remove CDL privileges from the license of any individual prohibited from performing safety-sensitive functions. 

States must now adopt a comparable state prohibition on operating a commercial motor vehicle for drivers that violate FMCSA’s drug and alcohol program requirements. States must be compliant with the rule by Nov. 18, 2024. 

However, ICSA expects many states will implement the federal requirement long before the 2024 date. More than half of the states have authority to adopt federal requirements “by reference” without having to go to their legislatures or through a state rule making process.
