A follow-up testing plan is the last part of the DOT return-to-duty process. It starts after a negative return-to-duty test and your return to safety-sensitive duty.
The rule in one line: your SAP writes the plan. It requires at least six unannounced follow-up tests in the first 12 months and can last up to 60 months.
What the plan covers
- The number of follow-up tests, at least six in the first 12 months
- The length of the plan, up to 60 months
- The type of testing, drugs, alcohol or both, based on your violation and the SAP's assessment
How follow-up tests work
- Unannounced. You are told to test with little or no warning, and the dates are not set in advance by you.
- Directly observed for drug tests.
- Ordered by your employer, or by you if you are an owner-operator. Only the SAP can change the plan.
What it costs and how to order
A directly observed DOT follow-up drug test is $135 at WorkOccMed. Order follow-up tests online and keep your SAP's plan close, so you know how many are due. For costs from start to finish, see what return to duty costs.
What happens when the plan is complete
When you finish the plan, completion is reported to the FMCSA Drug & Alcohol Clearinghouse. Keep copies of every result for your records.
