Designating a Substance Abuse Professional and the Return-to-Duty Process
In Clearinghouse documents from 2021 – see below:
- The driver must be evaluated by a substance abuse professional (SAP), who also oversees the driver’s treatment and education plan. A driver must contact a SAP and establish a relationship prior to designating him or her in the Clearinghouse. The driver selects his or her SAP (as required per § 40.287). The driver must send a request to designate his or her SAP in the Clearinghouse.
- Employers, or their designated consortia/third-party administrators (C/TPAs), and substance abuse professionals (SAPs) must now report select parts of the return-to-duty (RTD) process in the Clearinghouse, within specific time frames. This reported information will update the driver’s view of their RTD status.
