How Do the DOT Drug Testing Rules Affect Your Employees?

All employers of Department of Transportation mandated employees in safety-sensitive positions are required to comply with DOT drug and alcohol testing rules. Any employees who fail a test, or refuse to take a test, must be immediately removed from their safety-sensitive functions and referred to a program with a qualified Substance Abuse Professional (SAP).

As an employer, what is the best way to keep track of the myriad of DOT drug and alcohol testing rules and guidelines?

Why Drug and Alcohol Testing is Necessary

For employees serving the transportation industry, a safe work environment is critical. Co-workers, as well as the general public involved in transportation, are affected by the actions and decisions of every employee. Policies and practices have been adopted to create a safe and productive environment for everyone involved. Drug and alcohol use by DOT-mandated employees seriously compromises the safety of the workplace. In an effort to promote compliance, a program of scheduled and random drug and alcohol testing has been implemented and is required.

DOT Drug Testing Rules for Employers of DOT-Mandated Workers

  • Federal Policies. All employers of DOT-mandated workers must comply with federal policies regarding drug and alcohol testing. Each industry and mode of the DOT has different policies. Therefore, it is the responsibility of the employer to research the requirements and ensure that they are in compliance.
  • Education and Training. As part of the substance abuse testing program, employers are also required to provide training and education regarding the policies. Thus, ensuring all employees are aware of the requirements and are alerted to possible problems among co-workers in the workplace.
  • Access to Qualified SAPs. Employers are also required to provide a list of qualified SAP (Substance Abuse Professionals), or a referral to a service agent, to employees who may fail or refuse to comply with the testing processes.
