Drug and Alcohol Clearinghouse Public Safety Improvement Act of 2025

This bill requires trucking companies operating vehicles weighing over 10,000 pounds to report positive hair drug test results from pre-employment or random tests to the Drug and Alcohol Clearinghouse. It mandates that such tests come only from laboratories accredited by the College of American Pathologists for forensic hair testing and must follow Department of Health and Human Services scientific guidelines when available. The law updates existing reporting rules to include hair test results alongside traditional urine tests in the clearinghouse system. This directly affects commercial motor vehicle employers and drivers subject to federal drug testing requirements.
