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.
