Clearinghouse queries
Help with FMCSA Drug and Alcohol Clearinghouse registration and queries.
- Available remotely, all 50 states: Within the access you or FMCSA give us
The FMCSA Drug and Alcohol Clearinghouse is an online database of CDL drivers' drug and alcohol program violations. Employers must check it before hiring a CDL driver and once a year after that.
The Clearinghouse website can be confusing. We help you set up your account, buy queries, and run the ones you need. We only work inside the access you or FMCSA give us. We do not log in as you without your permission.
Who this is for
- Owner-operators who must query themselves
- Small carriers hiring CDL drivers
- Drivers who need to register and give consent
What we need from you
- Your Clearinghouse login, or the email you want to use to register
- Your USDOT number
- The driver's name and CDL details for the query
Price
- Clearinghouse query service
- $35
