Course Description
The U.S. Department of Transportation (DOT) and the Federal Motor Carrier Safety Administration (FMCSA) require motor carriers to enforce strict drug and alcohol testing programs. In this Drug and Alcohol Testing for CDL Drivers course, you’ll learn the key rules that keep commercial drivers safe and compliant on the road. These programs apply to CDL holders operating large or hazardous vehicles and include six types of testing, such as pre-employment, post-accident, random, and return-to-duty.
You’ll find out how tests are conducted using urine, breath, or oral fluid samples—and what happens if you refuse a test or test positive. You’ll also learn about removal from duty, how to qualify for return-to-duty testing, and the ongoing follow-up testing that may be required for up to five years.
If you or someone you know needs help, the course also explains how to find support through employee assistance programs or community services. Whether you’re a driver or a manager, this course gives you the tools to stay compliant and protect your livelihood.
