Frequently Asked Questions

Understanding why DOT drug testing training matters starts with the rules themselves. DOT drug testing rules began in 1988 and 1989. In 1991, Congress passed the “Omnibus Transportation Employee Testing Act of 1991,” which required drug and alcohol testing of safety-sensitive transportation employees to protect the American people from transportation workers who may be abusing substances while on the job. Pilots drinking on the job and truckers under the influence may be what comes to mind, but these regulations include a wide range of other safety-sensitive duties including railroad, transit, and pipeline workers. Nuclear power plant workers are tested under separate Nuclear Regulatory Commission rules (10 CFR Part 26). DOT procedures continue to set the bar for collection procedures and Drug-Free Workplace policies across the United States.

Highest Standards in the Industry

Since Congress passed the “Omnibus Transportation Employee Testing Act of 1991” the United States Department of Transportation has been a leader in drug testing regulation. It was among the first to adopt and require reliable standards for workplace testing, drug-free workplace policies, and collection procedures. Updated many times to address changes and procedural weaknesses, the DOT regulations in 49 CFR Part 40 are widely regarded as the benchmark for workplace drug testing in the United States, and many non-DOT programs model their procedures on them.

Safety and Security of the Collection Process

The DOT has been refining the collection process since the late 1980s and continues to update it. That ongoing improvement is one of the benefits of DOT training. Every five years, DOT collectors undergo refresher training (49 CFR 40.33(e)) to learn about changes and to “refresh” their memory on prior training procedures. Because the DOT has an important mandate to protect the public from accidents related to substance abuse, its procedures are built around collection safety, security, and specimen integrity.

Reduce Liability

Consider Bob and John. Bob has his Driver’s License and John has a Driver’s License, a Racing License, and is a trained stunt driver. Both are legally able to drive on the highway, but who would be best able to handle a potential head-on collision? John’s training as a racer and a stunt driver would certainly give him the best chance at avoiding that serious accident. This situation can be used to compare the difference in risk and potential liability for drug testing collectors who simply have Non-DOT collection training (Bob) and those who are trained in both Non-DOT and DOT regulations (John). Even during Non-DOT collections, a trained DOT Collector is better able to recognize, handle, and avoid the risk of a potentially hazardous collection.

More Opportunity

Whether a person already owns a drug testing business, is starting one, or is a plan administrator, DOT training can improve that person’s opportunities and effectiveness. DOT training includes many procedural guidelines that can be crossed over easily into less regulated, non-DOT collections to improve the safety and security of the overall collection process. Even for a collector who never performs a DOT collection, the benefits for all future collections make DOT training a valuable investment, and DOT testing is common across the transportation industry. According to the Bureau of Transportation Statistics, transportation and transportation-related industries employed about 16.2 million people in 2025, including about 6.6 million in the transportation and warehousing industry (BTS Transportation Economic Trends). DOT agency and U.S. Coast Guard testing rules together cover approximately 6.5 million employees who perform safety-sensitive functions (ODAPC). In May 2025, there were about 2.1 million heavy and tractor-trailer truck drivers in the United States (BLS Occupational Employment and Wage Statistics). The opportunity is there for collectors with the skills, training, and ambition to take the first step.

The NRC fitness-for-duty (FFD) program rules are in 10 CFR Part 26. They apply to licensees authorized to operate nuclear power reactors, licensees that possess, use, or transport formula quantities of strategic special nuclear material, and certain construction-stage license applicants and permit holders, with different subparts applying to different groups. A contractor or vendor program is covered to the extent a licensee relies on it. Part 26 does not apply to spent fuel storage facility licensees or to non-power facility licensees that possess formula quantities of irradiated strategic special nuclear material (10 CFR 26.3).

FFD programs must provide reasonable assurance that individuals are trustworthy and reliable as shown by avoiding substance abuse, and that they are not under the influence of any substance, legal or illegal, or impaired from any cause that adversely affects their ability to perform their duties safely. Programs also provide for early detection of individuals who are not fit, workplaces free from the presence and effects of illegal drugs and alcohol, and management of fatigue (10 CFR 26.23).

At a nuclear power plant, the rules cover individuals granted unescorted access to protected areas and those required to report to the Technical Support Center or Emergency Operations Facility. Individuals who perform listed duties, such as operating safety-significant systems, fire brigade duties, or security duties such as armed security force officer, alarm station operator, response team leader, or watchman, are also subject to the work hour controls (10 CFR 26.4).

Program elements include:

• Drug and alcohol testing. Tests are given pre-access, for cause, post-event, as follow-up, and on a random basis. Random testing must equal at least 50 percent of the population subject to the FFD program each year (10 CFR 26.31(d)(2)(vii)). The minimum panel covers marijuana metabolite, cocaine metabolite, opioids, amphetamines, phencyclidine, and alcohol (10 CFR 26.31).
• Training. Individuals learn the FFD policy, the roles of others such as the MRO and EAP staff, and how to detect impairment. They pass an examination with a minimum score of 80 percent before initial authorization and complete refresher training on a nominal 12-month frequency, unless they pass an annual examination instead (10 CFR 26.29).
• Behavioral observation by individuals trained to detect signs of drug or alcohol use or impairment (10 CFR 26.33).
• An employee assistance program offering confidential assessment, short-term counseling, referral services, and treatment monitoring (10 CFR 26.35).

Part 26 also has separate subparts for fatigue management, construction sites, and facilities licensed under 10 CFR Part 53.
