What employers need to know about DOT drug and alcohol testing
from U.S. Department of Transportation Office of the Secretary
If you employ safety-sensitive workers who must have Department of Transportation drug and alcohol tests, or you manage a DOT drug or alcohol testing program, this publication can help you understand how to run an excellent program that meets DOT requirements. This is not a legal document that adds to or makes any official interpretations of DOT rules. This publication is for educational purposes only. This booklet is a companion to our earlier publication for employees, "What Employees Need to Know About DOT Drug & Alcohol Testing."
