## Abstract

In a final rule published in the Federal Register on October 7, 2021, FMCSA amended its regulations to establish requirements for State Driver's Licensing Agencies to access and use information obtained through the Drug and Alcohol Clearinghouse, an FMCSA- administered database containing driver-specific controlled substance and alcohol records. The final rule included amendatory instructions that need to be corrected because of a subsequent, unrelated rulemaking action affecting the same section of the Federal Motor Carrier Safety Regulations. This notice makes that correction.
