Locate a Qualified Substance Abuse Professional List

Anyone designated to perform duties defined by the US Department of Transportation (DOT) as safety-sensitive, such as driving a large truck, working on pipelines, operating a train or ferry, or repairing an airplane, is subject to DOT workplace drug and alcohol testing. The DOT recognizes the need for a drug and alcohol-free transportation industry that is safe for the traveling public, co-workers and employees. If an employee fails, or refuses to take, the DOT mandated workplace drug and/or alcohol test, they must stop performing their safety-sensitive duties and see a Substance Abuse Professional (SAP). To complete that task, that employer must provide a list of a qualified Substance Abuse Professionals or refer to a service agent.

Help from a Qualified SAP

A SAP is an expert who evaluates employees who have violated a DOT mandatory drug and/or alcohol test. Their fundamental responsibility is to comprehensively and clinically assess the employee to determine what kind of assistance the employee needs to resolve problems associated with alcohol or drug use. The SAP recommends education, counseling, or treatment, which the employee must comply with before returning to a DOT safety-sensitive position. The SAP also makes recommendations concerning follow-up testing, aftercare and even sends a report of compliance to your employer.

A Substance Abuse Professional does not support the employee or employer, his or her main responsibility is to guarantee public safety by issuing the correct recommendations.
