DOT Drug Testing

The Department of Transportation (DOT) requires alcohol and drug testing for those working in safety-sensitive positions, such as aviation, boating, mass transit, trucking, railroads and other transportation areas.  The DOT has strict regulations on the entire testing process from administration of the test, interpretations on results, and on procedures for testing positive. RaBu Diagnostic’s DOT alcohol and drug tests meet all of these guidelines that the DOT has put in place.

DOT Drug Tests

The drug test required for DOT compliance is the five-panel, which screens for:

  • Amphetamines including MDMA (Ecstasy) and 6AM
  • Marijuana
  • Basic Opiates like Codeine and Morphine, plus Heroin
  • Cocaine
  • Phencyclidine (PCP)

Under the category of amphetamines, DOT testing includes confirmatory testing for methamphetamine and amphetamine, plus, confirmatory testing has also been added for MDEA, MDMA, MDA and MDMA. For opiates, laboratory testing includes heroin, morphine and codeine, but not prescription opiates like hydrocodone and oxycodone.

Other DOT regulations include:

  • Employers must report the number of verified positive drug tests on their annual MIS report.
  • Employers must report the number of failed breath alcohol tests.
  • Labs must report on drug metabolites that they verify as positive

Employers, Employees and DOT Compliance

Employers are responsible for meeting procedures and requirements outlined in DOT Rule 49 DFR Part 40 Section 40.11 Employers are also responsible for the actions of all representatives,  agents, and officials carrying out the requirements for DOT compliance.

If an applicant for employment refuses a drug test or tests positive they are not permitted to perform safety-sensitive duties. Existing employees who either test positive or refuse a test may not return to employment that entails safety-sensitive duties until they have seen a substance abuse counselor and have successfully complete the return-to-duty procedures.

Employees who drive commercial vehicles are not allowed to use habit-forming drugs, narcotics or amphetamines. However, if a driver is prescribed one of these substances by a licensed medical practitioner, it may be allowed. The doctor must be familiar with the driver’s medical history and confirm that the prescribed drug will not adversely affect the driver’s ability to operate the vehicle safely.
