Commercial drivers who use drugs will have a tough time keeping a job or finding a new one, once a new federal drug database goes live Oct. 1. The Commercial Driver's License Drug and Alcohol Clearinghouse  is under development by the Federal Motor Carrier Safety Administration (FMCSA) , which is accepting public comments until April 21.

The clearinghouse will compile a database of commercial drivers' positive drug and alcohol tests, as well as any refusals to submit to testing. Prospective employers would be required to obtain written permission to access the applicant’s data, but a refusal would most likely exclude an applicant from further consideration.

The process, according to a posting by the FMCSA, would “increase highway safety by ensuring CDL holders, who have tested positive or have refused to submit to testing, have completed the U.S. DOT’s return to duty process before driving [commercial motor vehicles] in interstate and intrastate commerce.” It will also help ensure that employers are meeting drug and alcohol testing responsibilities, according to the FMCSA.

The testing and other requirements would apply to all commercial license holders, including school bus drivers, according to School Bus Fleet.
