The Federal Motor Carrier Safety Administration (FMCSA) is the largest of all the agencies under the Department of Transportation (DOT). FMCSA launched a real-time online database referred to as the Clearinghouse on Jan. 6, 2020. This has changed the landscape for keeping our nation’s roadways safe and allowing drivers to work safely. However, employers still have many questions on the requirements to maintain compliance within the Clearinghouse. Part of remaining in compliance involves the DOT return-to-duty (RTD) process as outlined in 49 CFR Part 40, often referred to as Part 40. Employers having DOT safety-sensitive employees are required to perform workplace drug testing, but it is often misunderstood when testing is required and how to return an employee to safety-sensitive duty. This presentation will cover the pertinent aspects of the Clearinghouse and the regulations required within the RTD process. Sandra Serrano, chief development officer at the American Substance Abuse Professionals, will share the astonishing statistics the Clearinghouse has revealed on drug and alcohol testing violations over the course of the year.
