• People who apply for or are transferring into safety-sensitive position, i.e., operating CMVs requiring CDLs, must be tested for controlled substances.

All applicants for employment on a permanent or temporary basis to operate commercial motor vehicles (CMVs) requiring a commercial driver’s license (CDL), must be given pre-employment tests for controlled substances. Those existing employees transferring into a safety-sensitive position must also be given a pre-employment test.

The purpose of pre-employment testing is to deter and detect controlled substances abuse by driver-applicants. Pre-employment testing identifies drivers who could bring a controlled substances problem into an organization.

A driver-applicant shall not be allowed to perform as a driver unless the employer has a verified negative controlled substances test result from the medical review officer (MRO) for the driver-applicant.
