1. Complete the recommended program
You complete the specific education or treatment program your SAP recommended. Substituting a different program does not satisfy DOT requirements — even if the alternative looks similar. If you have logistical or financial barriers to completing the recommended program, tell us as soon as possible so we can adjust the recommendation if appropriate.
2. Follow-up evaluation
Once you complete the program, you return to the same SAP for the follow-up evaluation. The SAP determines whether you've demonstrated successful compliance. This is a single appointment, usually 30–60 minutes.
3. Return-to-duty test
If you're cleared at the follow-up evaluation, your employer arranges a directly observed return-to-duty drug test (and an alcohol test if alcohol was involved in the original violation). A passing result is required before you can perform any DOT safety-sensitive function.
4. Follow-up testing plan
Your SAP also issues a follow-up testing plan — a schedule of unannounced tests during your first months back on duty. DOT requires a minimum of six tests in the first 12 months. Depending on your situation, the SAP may extend follow-up testing up to five years. Your employer administers these tests; you don't get advance notice.
If you fail a follow-up test
A failed follow-up test is treated as a new DOT violation — immediate removal from safety-sensitive duty, and a full return-to-duty process again from the start. For CDL drivers, this is reported again to the FMCSA Clearinghouse. Treat follow-up testing seriously.
