As directed by the Federal Motor Carrier Safety Administration (FMCSA) and the Department of Transportation (DOT), all CDL drivers and their employers are required to follow the rules related to DOT drug tests.
Who is given a DOT drug test?
Drivers of commercial motor vehicles (CMVs) are required to take a drug test and their employers must ensure their drivers are tested before operating a CMV.
Below is a full list of those required to be tested.
- employers of CDL drivers operating CMVs on public roads
- CDL drivers who operate CMVs on public roads
- interstate motor carriers
- intrastate motor carriers
- federal, state, and local governments
- civic organizations (disabled veteran transport, boy/girl scouts, etc.)
- faith-based organizations
What substances are tested?
The DOT requires testing of alcohol and five drug classes, including:
- Amphetamines or methamphetamines
Alcohol tests will identify alcohol in the system at .02 BAC and more.
Motor carriers can also implement a separate testing program in addition to, and distinct from, the required DOT testing program, under which they are able to test for other drugs.
What types of DOT drug tests are there and when are they given?
DOT drug and alcohol tests are given in several different scenarios, including:
- pre-employment – before starting work as a CDL driver and operating a CMV
- post-accident – drug and alcohol tests may be required after an accident depending on the circumstances. Learn when post-accident drug tests are required.
- random – random testing programs are required by law for all DOT-regulated motor carriers
- reasonable suspicion – if a driver appears to be under the influence of drugs or alcohol, an area in which supervisors must be trained in identifying.
- return-to-duty – required of drivers who tested positive, refused, or violated the law
- follow-up – required of drivers who tested positive, refused, or violated the law
What is the DOT drug testing process?
The DOT has a strict process for administering drug tests and the steps are the same for all six types.
- Go to the collection site with a valid ID and provide a sample before leaving.
- Provide your urine sample in the designated collection area. The collection process will be private unless required, as in a return-to-duty or follow-up test.
- When finished with the sample, provide the container to the collector and observe as they split the sample into two containers, seal them with tamper-evident tape and allow you to sign the tape before you leave.
- Provide your contact information and verify your name and date of birth so the Medical Review Officer (MRO) can get in touch with the results.
