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.

6+

tests in your first 12 months back

Up to 5yrs

how long the plan can last

Observed

every follow-up test is watched

No notice

tests are unannounced

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.

See 49 CFR §40.67(b), §40.307, §40.309 and §40.329(c)

Still early in the process?

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.
