Controlled Substance and Alcohol Use and Testing

August 19, 2020


This section is intended to provide controlled substance and alcohol testing guidance for employers of individuals that are required to possess a commercial driver’s license to operate a commercial motor vehicle, such as a school bus, school activity bus, and multifunction school activity bus.

Texas independent school districts are exempt from the Federal Motor Carrier Safety Regulations (FMCSR) with the exception of Part 382 (Controlled Substances and Alcohol Use and Testing).  49 CFR Part 382 applies to every person and to all employers of such persons who operate a commercial motor vehicle in commerce in any State, and is subject to commercial driver’s license requirements.

The purpose of these tests is to establish programs designed to help prevent accidents and injuries resulting from the misuse of alcohol or use of controlled substances by drivers of commercial motor vehicles.
