Return-to-Duty Process

To return to work, the following must occur:

  • 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.

Our licensed professional team will evaluates employees who have violated a Department of Transportation drug and alcohol program regulation and make recommendations concerning education,
treatment, follow-up testing, and aftercare. We will then determine whether it is safe for the employee to return to work.

What is DOT Substance Abuse Professional?

DOT SAP is a specific type of evaluation and treatment program required by the Department of Transportation for safety-sensitive employees who violate the drug and alcohol testing regulations. These employees, including commercial drivers, pilots, railroad workers, and pipeline operators, are subject to regular drug and alcohol testing to ensure they are fit for duty and not impaired by substances. If an employee tests positive for drugs or alcohol or refuses to test, they must undergo a SAP evaluation to determine whether they have a substance abuse problem that needs treatment.

A DOT SAP evaluation is a comprehensive process that includes an assessment of the employee’s substance abuse history, work situation, and clinical evaluation by a qualified DOT SAP. The SAP must be knowledgeable about the DOT regulations, and must meet the qualifications and requirements laid out by the DOT. The SAP evaluates the employee to determine whether they have a substance use disorder and recommends the appropriate course of treatment.

Who needs DOT Substance Abuse Professional?

If you’re a safety-sensitive employee who has violated the DOT drug and alcohol testing regulations or if you’re an employer who has an employee who has tested positive, refused to test, or violated the regulations, then you need a DOT SAP evaluation. It’s important to note that if an employee has a substance abuse problem, they will be unable to return to safety-sensitive duty until they have completed the SAP evaluation, complied with treatment recommendations, and passed a return-to-duty drug and alcohol test. Therefore, it’s in the best interest of both employees and employers to address substance abuse issues quickly and effectively.
