Return-to-Work (RTW) Process

Definition

The Return-to-Work (RTW) - also called Return-to-Duty (RTD) - process is the regulatory pathway under 49 CFR §40.305 that lets a driver who tested positive or refused a DOT test return to safety-sensitive functions. The driver must (1) complete a SAP evaluation, (2) complete the SAP-prescribed education or treatment program, (3) pass a SAP follow-up evaluation, (4) pass a return-to-duty observed test, and (5) complete the SAP-prescribed follow-up testing plan. The Clearinghouse tracks each step automatically. Carriers hiring a driver currently in the RTW process should confirm Clearinghouse status - drivers in active RTW are not yet eligible for safety-sensitive duty until step 4 is complete.
