Failing a DOT drug or alcohol test (positive result or refusal) immediately places you in “prohibited” status in the FMCSA Drug and Alcohol Clearinghouse, barring you from safety-sensitive functions like driving. In 2026, states enforce mandatory CDL downgrades for prohibited drivers until Return-to-Duty (RTD) completion, with violations visible for 5 years or until cleared. Oral fluid testing rollout remains delayed (expected late 2025/early 2026), so urine tests are standard; random rates hold at 50% drug / 10% alcohol.
Step-by-Step RTD Process
- Immediate Impact: Removal from duties; violation reported by employer/MRO to Clearinghouse.
- SAP Evaluation: Contact a Substance Abuse Professional (SAP) for assessment and required education/treatment plan.
- Program Completion: Finish SAP recommendations.
- Return-to-Duty Test: Negative result reported to Clearinghouse by employer.
- Follow-Up Testing: Minimum 6 unannounced tests in the first year (SAP may extend); employer reports compliance.
- Record Duration: Violation stays until RTD/follow-up complete; visible 5 years max.
Prohibited status blocks hiring, renewals, and upgrades—states query Clearinghouse pre-issuance.
