Positive DOT Test
In 1991 The United States Congress recognized the need for a dot free transportation industry which prompted them to pass the Omnibus Transportation Employee Testing Act, requiring DOT agencies to conduct dot testing on safety-sensitive transportation employees. https://www.phmsa.dot.gov/
You can find these rules and regulations published in the Office of dot Policy Compliance (ODAPC). The specific laws can be found in Code 49 of Federal Regulations (CFR) and in Part 40, which includes the procedures to use when testing and how to return an employee to safety-sensitive duty.

Who is impacted?
Anyone who has been designated as a DOT safety-sensitive employee is subject to dot testing. The tasks performed by the employee, not their job title, determine whether they are safety-sensitive employees. Even if you are qualified for duty but are not currently performing it, you are still eligible to be tested if you need to fill in for an emergency. These employees have jobs that can jeopardize their own and the public’s safety.
