Allows submission of positive hair drug test results to the Drug and Alcohol Clearinghouse.

The Drug and Alcohol Clearinghouse Public Safety Improvement Act of 2025 amends title 49, United States Code, to allow the submission of positive hair drug test results to the Drug and Alcohol Clearinghouse of the Federal Motor Carrier Safety Administration. This applies to motor carriers using vehicles weighing not less than 10,000 pounds. The test results must come from a laboratory accredited by the College of American Pathologists and follow Department of Health and Human Services guidelines. The Secretary of Transportation must issue regulations within a year to implement these changes.
