Employer FAQs
The Federal Motor Carrier Safety Administration (FMCSA) requires carriers and any employee with a commercial driver’s license (CDL) to be in a DOT random drug and alcohol testing pool.
Reasonable suspicion is a belief, based on specific and observable facts (such as appearance, behavior, speech, or body odors), that an employee is under the influence of drugs or alcohol. This is a common trigger for required testing under both DOT and TnDFWP policies.
While some states have legalized marijuana, it remains illegal in Tennessee. Employers in Tennessee, especially those in the Drug Free Workplace Program, generally have a zero-tolerance policy. A positive test for marijuana can be grounds for disciplinary action, including termination.
Yes. All CDL holders, including owner-operators with no employees, must be enrolled in a DOT random drug and alcohol testing pool. Owner-operators typically join a consortium to meet this requirement.
The DOT requires testing in six situations:
- Pre-employment
- Reasonable suspicion
- Post-accident
- Random
- Return-to-duty
- Follow-up
A standard DOT drug test screens for five classes of substances:
- Marijuana (THC)
- Cocaine
- Amphetamines (including methamphetamine, MDMA)
- Opioids (including codeine, morphine, heroin, oxycodone, hydrocodone)

If the driver was issued a citation, the following must also involve:
- Bodily injury to any person who receives medical treatment away from the scene of the accident or

Post-accident drug testing should be done within 32 hours of the accident. If the testing cannot be done within the time limits, the employer should cease attempts to conduct post-accident tests. The employer should maintain on file that explains why the post-accident test was not performed.
