Follow-up testing, explained
Passing your return-to-duty test isn't the end. Your SAP also sets a follow-up testing plan, and it's the part of the process that surprises drivers most.

How it works
1
Your SAP sets the plan
The SAP decides how many tests and for how long, and whether they're for drugs, alcohol or both. Your employer can't reduce it.
2
Your employer runs it
Your employer, or their C/TPA, schedules the tests. You won't be told the schedule, and you won't get a copy of the plan.
3
It follows you
If you change jobs, the plan transfers to your new DOT employer and picks up where it left off.
4
It's in addition to random testing
You're still in your employer's random testing pool. Follow-up tests are on top of that.
5
Missing one counts as a refusal
Failing to show up for a follow-up test is treated like refusing to test, which is a new violation.

No current or prospective employer?
FMCSA permits a driver without a current or prospective employer to register in the Clearinghouse as an owner-operator and designate a C/TPA for the limited purpose of completing the return-to-duty process. The designated C/TPA can direct the driver to take the return-to-duty test and report the negative result to the Clearinghouse.
