What does this do?
This bill would require trucking companies to report positive hair drug test results to the federal Drug and Alcohol Clearinghouse database. It covers hair tests given before hiring or during random testing, but only when the test uses an approved device and an accredited lab. The Department of Transportation would have one year to write the rules for how this works.
Who does it affect?
This bill affects trucking and motor carrier companies that operate vehicles weighing 10,000 pounds or more. It also affects commercial drivers those companies employ or consider for hire.
Why does it matter?
A positive hair test result would be treated the same as an employer knowing directly that a driver used drugs, which can affect whether that driver is allowed to work. Drivers whose results are reported would be entered into a federal database that employers can check.
