Registration Now Open for FMCSA’s Mandatory Drug & Alcohol Clearinghouse

Print this Article | Send to Colleague

Starting January 6, 2020, commercial motor vehicle carriers are required to be registered with the new, secure Federal Motor Carrier Safety Administration (FMCSA) Drug and Alcohol Clearinghouse. Once registered, carriers are required to input all of their CDL-holders’ positive drug and alcohol tests, refused tests and return-to-duty testing elements. Carriers are also mandated to query the Clearinghouse for prospective drivers that may have drug and alcohol program violations and annually query for all drivers to check for any positive tests before a driver is allowed to operate a commercial motor vehicle (CMV) on public roadways.

Furthermore, carriers are required to have content from their drivers before conducting a driver query of the Clearinghouse. Drivers wishing to continue to drive for the carrier will need to register with the Clearinghouse to grant consent and to review their own information. Driver and carrier registration is completed online through FMCSA’s website.

Specifically, the elements for the Clearinghouse all carriers and drivers need to know are:
1. This is NOT a proposal; this program was finalized in December 2016 and becomes effective January 6, 2020.

2. Carriers are required to be registered with the Clearinghouse.

3. Drivers are not required to be registered, but in order for a carrier to fulfill their responsibility they will need to query each employed driver making it imperative for drivers to register should they wish to maintain employment

4. The Clearinghouse will contain only driver positive drug/alcohol tests, refused tests and the steps completed for the return-to-duty process after a positive test.

5. Information gathered in the Clearinghouse will be nationwide, meaning drivers that move jobs frequently will have information in the Clearinghouse accessible to all current and future carriers from January 6, 2020 moving forward.

6. There are two types of queries that can be performed: full and limited. A full query is required for pre-employment and if a positive test is shown in the Clearinghouse. A limited query is an annual query by carriers of all their CDL-holders to determine if a positive test is shown in the Clearinghouse.

7. Carriers can use third-party services to both report violations and query their drivers. However, third-party services must be made as the carrier’s designated service agent when the carrier registers and the third-party must be an authorized service registered through FMCSA.

8. Querying the Clearinghouse does have a cost. While single queries cost $1.25 for limited and full queries, carriers can purchase “bundles” of queries based on the carriers needs and number of drivers.

9. Training for personnel with the carrier and drivers will be key for a smooth registration and for maintaining compliance.
