- Aftercare Recommendations: As part of the follow-up evaluation, the SAP may recommend aftercare or continuing care. This could include support group meetings, education, and additional counseling.
- Return-to-Duty Process: If the SAP determines that the individual has successfully complied with recommendations. They will send a report to the employer stating that the driver can return to duty.
