Follow-Up Testing Schedule Management

When a driver returns to duty after a positive test, SAP prescribes a follow-up testing schedule the carrier must execute. The schedule is the SAP's call — the carrier executes it.

Schedule basics

• Minimum: 6 tests in the first 12 months post-return
• Maximum: up to 60 months (5 years)
• Random scheduling: within each defined window
• Testing types: controlled substances + alcohol (alcohol only if SAP prescribed)

Carrier execution

1. Receive SAP follow-up testing report
2. Enter schedule into testing system (or consortium)
3. Generate random test dates within each window
4. Conduct tests; report results
5. If positive or refusal → driver returns to SAP process (back to step 1)
6. If all complete → schedule complete

Missed tests

• A missed test is NOT automatically a refusal
• Driver is responsible for being available; carrier is responsible for scheduling
• If schedule lapses due to driver-controlled circumstances (vacation, leave), the schedule extends
• If carrier fails to schedule a test, the carrier is in violation

Transitioning the schedule to a new employer

Per Clearinghouse:

• New employer is notified of remaining follow-up tests when querying
• New employer assumes the schedule from the date of hire
• Driver may complete the schedule across multiple employers as long as it's continuous

Reporting

• Follow-up test results reported to Clearinghouse within 3 business days
• Negative results = continuing schedule
• Positive results = back to SAP process; reported with appropriate flag

Common carrier errors

• Letting schedule lapse beyond 12 months without an extension
• Not communicating with consortium/TPA when driver leaves
• Forgetting to check Clearinghouse for inherited schedules on new hires

CFR citations

• 49 CFR § 382.605
• 49 CFR § 40.307
• 49 CFR Part 40 Subpart O

How Compass surfaces this

This skill is searchable in the Compass Ask interface and runs against the carrier's actual fleet data when invoked from within the relevant tracker. It is read-only — no actions are taken without explicit user approval.
