Drug and Alcohol Clearinghouse Guide for Carriers

The Drug and Alcohol Clearinghouse matters because it gives carriers a central place to check whether a driver has unresolved DOT drug and alcohol violations. That makes hiring and ongoing monitoring much more consistent.

Carriers need to understand when queries are required and what to do with the results. Pre-employment checks are only the starting point. Employers also need limited or full annual queries for active drivers, and they must keep the records that prove the queries were done.

If a violation appears, the return-to-duty process must be handled correctly. That means the driver cannot simply return to work because a test came back clean. The DOT process requires the right steps, the right documentation, and follow-up testing.

The Clearinghouse is one of those systems that only helps when it is used consistently. Miss a query or mishandle a record, and the whole compliance story gets weaker quickly.
