Frequently Asked Questions
What types of DOT drug and alcohol tests are required?
Per 49 CFR Part 382: pre-employment (every CDL hire), random (50% of CDL drivers per year for drugs, 10% for alcohol), reasonable suspicion (after observed behavior), post-accident (after qualifying crashes), return-to-duty (after a violation), and follow-up (per SAP recommendations). All tests use the federal 5-panel: marijuana, cocaine, opiates, amphetamines, PCP. Alcohol is breath or saliva.
When must a DOT random drug test be performed?
Anytime during a driver's on-duty hours. The driver must report to the collection site immediately upon notification. Testing must be unannounced and the random selection cannot be predictable. Random pool composition and selection methodology must be documented. Annual random testing rate is 50% for drugs, 10% for alcohol.
What happens if a CDL driver refuses a DOT drug test?
Refusal is treated identically to a positive result: immediate prohibition from safety-sensitive duties, Clearinghouse entry, full return-to-duty process required. 'Refusal' includes failing to appear for testing, not providing sufficient specimen, leaving before completion, or any conduct that obstructs the testing process per 49 CFR 40.191.
Who can be a DOT-qualified Substance Abuse Professional (SAP)?
Per 49 CFR 40.281: a licensed physician, psychologist, social worker, employee assistance professional, or addiction counselor with credentials, plus DOT-specific training and continuing education. The SAP evaluates the violator, recommends treatment if appropriate, and authorizes return-to-duty after compliance. Employers cannot select friendly SAPs — drivers choose from the SAP roster.
