Drug & Alcohol Clearinghouse - Department of Transportation

The FMCSA DOT Clearinghouse is an online database managed by the Federal Motor Carrier Safety Administration (FMCSA) that tracks drug and alcohol violations of commercial driver's license (CDL) and commercial learner's permit (CLP) holders. It is part of the Department of Transportation (DOT) regulations and helps employers, government agencies, and authorized users maintain compliance with federal regulations.

  2. Access real-time data: It provides immediate access to violations like failed or refused drug tests, providing transparency for employers in ensuring the safety of their workforce.
  3. Ensure compliance: By using the Clearinghouse, employers can better meet DOT requirements, keeping their companies in compliance with federal safety regulations, and help promote safety on the roadways.
