DOT Drug Testing Services to Keep Your Business Compliant

If your business operates in a safety-sensitive industry regulated by the Department of Transportation (DOT), compliance isn’t optional—it’s critical. At Patriot Safety and Services, we provide comprehensive DOT drug testing solutions that help you meet federal regulations, reduce liability, and maintain a safe working environment.
We proudly serve employers across the transportation, aviation, pipeline, and railroad industries with fully compliant and expertly managed drug testing programs.

What Is DOT Drug Testing?

DOT drug testing refers to federally mandated testing for employees in safety-sensitive roles, such as commercial truck drivers, pilots, railroad workers, and pipeline operators. The testing is regulated by the DOT and governed by 49 CFR Part 40, which outlines how drug and alcohol testing must be conducted.
DOT drug testing is designed to detect the use of illegal substances and ensure that employees are fit to perform duties where impairment could lead to serious safety hazards.

Who Is Required to Take a DOT Drug Test?

DOT drug testing applies to employees under the following federal agencies:

• FMCSA (Federal Motor Carrier Safety Administration) – Truck and bus drivers
• FAA (Federal Aviation Administration) – Flight crews and ground service personnel
• PHMSA (Pipeline and Hazardous Materials Safety Administration) – Pipeline operators
• FRA (Federal Railroad Administration) – Train operators and signal workers
• FTA (Federal Transit Administration) – Transit employees
• USCG (United States Coast Guard) – Maritime workers

If you operate in any of these sectors, it is your responsibility to implement a compliant drug testing program.

When Is DOT Drug Testing Required?

We help you stay on track by providing testing for all required scenarios:

• Pre-Employment Drug Testing: Before an employee performs any DOT-covered safety-sensitive duties, they must undergo a drug test and receive a negative result.

• Random Drug Testing: Employees are randomly selected throughout the year for unannounced drug and alcohol testing.

• Post-Accident Testing: Testing must be performed after specific accidents or incidents to determine whether drugs or alcohol were contributing factors.

• Reasonable Suspicion Testing: Supervisors who have been trained to identify signs of drug or alcohol use may require a test based on observed behavior.

• Return-to-Duty Testing: After a violation, an employee must complete a return-to-duty process which includes drug testing and a Substance Abuse Professional (SAP) evaluation.

• Follow-Up Testing: Ongoing testing is required for employees returning from a violation to ensure continued compliance.
