Which Employers Must Conduct DOT Random Testing

Any employer whose workers perform safety-sensitive functions under a federal DOT agency is required to conduct a DOT random drug and alcohol testing program. Six agencies govern these requirements: the Federal Motor Carrier Safety Administration (FMCSA), the Federal Aviation Administration (FAA), the Federal Railroad Administration (FRA), the Pipeline and Hazardous Materials Safety Administration (PHMSA), the Federal Transit Administration (FTA), and the United States Coast Guard (USCG). Each agency sets its own testing rates, covered positions, and timing rules based on the roles involved.

In Jefferson County, FMCSA-regulated employers include businesses operating commercial motor vehicles with CDL drivers. FTA-regulated employers include public transit operators such as the Transit Authority of River City (TARC). Other CDL-holding employees, including private motor carriers, may also fall under random testing requirements depending on the nature of their operations. We work with employers across all six agency types and can help you confirm which rules apply to your workforce.

What Our DOT Random Program Includes

A compliant program requires more than showing up for a test. Before random testing can begin, DOT regulations require a written policy documenting how employees are selected, what tests will be conducted, and what happens after a positive result or refusal. We handle policy creation from the start, so there’s no gap between your paperwork and your practice.

For testing, we provide certified breathalyzer tests, urinalysis, and saliva alcohol tests to meet DOT requirements. Random selection must follow a scientifically valid method that gives each covered employee an equal statistical chance of being selected in any given period. When coming to our facility isn’t practical, on-site testing brings our certified collectors to your location. And because compliance doesn’t stop after your first round of tests, we offer ongoing program management to keep your program current with changing federal requirements.

Frequently Asked Questions

What Is the Current DOT Random Drug Testing Rate for FMCSA Employers?

Under 49 CFR Part 382.305, the minimum annual random drug testing rate is 50% of the average number of driver positions. The minimum random alcohol testing rate is 10%. FMCSA raised the drug testing rate to 50% in 2020, up from 25%; the alcohol rate has remained at 10%. Rates for other DOT agencies vary, so it’s worth confirming what applies to your specific workforce.

Do We Need a Written Policy Before Starting Random Testing?

Yes. DOT regulations require a written drug and alcohol testing policy before testing begins. The policy must describe how employees are selected, what tests are conducted, and the consequences of a positive result or refusal to test. We assist with policy creation as part of our program support. You don’t have to start from scratch on your own.
