FMCSA Drug & Alcohol Clearinghouse Services

DOT-Compliant. Hassle-Free. Fully Managed by Experts.



If you're an Owner-Operator or trucking company, staying compliant with the FMCSA Drug & Alcohol Clearinghouse isn't optional - it's required.

At Corporate Testing Solutions, Inc., we make it simple. As your Third-Party Administrator (TPA), we handle everything you need to stay compliant, avoid fines, and keep your business moving.

What We Do for You:

  • Clearinghouse Account Registration - We'll assist in setting up your FMCSA Clearinghouse account the right way - or help fix it if it's already been set up incorrectly.
  • Pre-Employment Queries - Required before hiring any CDL driver. We run and document these for you.
  • Annual Limited Queries - Every driver must be checked once a year - we track and perform these automatically.
  • Violation & Return-to-Duty Reporting - If a driver fails or refuses a test, we report all required info to the Clearinghouse on your behalf.
  • Audit-Ready Records & Support - Need help with a DOT audit? We'll ensure your Clearinghouse records are accurate and up to date.
