The Clearinghouse, a web-based system found at, will provide Federal Motor Carrier Safety Administration (FMCSA) and employers of commercial motor vehicle (CMV) drivers with the necessary tools to identify drivers who are prohibited from operating CMVs due to DOT drug and alcohol program violations. The Clearinghouse will help ensure that such drivers receive the evaluation and treatment required by DOT regulation before being permitted to operate a CMV on public roads. Information maintained in the Clearinghouse will enable employers to identify drivers who commit a drug or alcohol program violation while working for one employer but fail to subsequently inform another employer. Records of drug and alcohol program violations will remain in the Clearinghouse for five years, or until the driver has completed the return-to-duty process, whichever is later.

All SAPs who work with or plan to work with covered employees under the Federal Motor Carrier Safety Administration must register with the Clearinghouse.

Mandated by Congress, the Clearinghouse Final Rule can be found at
