DOT Clearinghouse Compliance Help in Wisconsin

One-truck operators and the C/TPA requirement

Our carrier directory lists about 65,620 carrier records in Wisconsin, and about 35,750 show a single power unit. Some of those records will be owner-operators who employ themselves as CDL drivers.

An owner-operator subject to Part 382 must designate a consortium/third-party administrator (C/TPA) in the Clearinghouse for required employer reporting. A designated C/TPA may also conduct Clearinghouse queries if authorized. Separately, a self-employed driver who is not leased to another motor carrier must participate in a compliant random testing program, normally through a consortium. Do not assume that Clearinghouse designation alone means the same provider is administering every part of the testing program.

Hiring seasonal and returning CDL drivers

Construction, building materials, grain and farm supplies are among the cargo types appearing frequently in the Wisconsin directory. Where an employer hires a driver for safety-sensitive work covered by Part 382, a full pre-employment Clearinghouse query must be completed before that work begins. The driver gives specific electronic consent for the full query through the Clearinghouse.

The same point matters when a carrier adds seasonal drivers, brings a former driver back onto payroll or expands from an owner-operated truck to employed CDL drivers. About 5,350 Wisconsin carrier records in the directory first registered with FMCSA in 2025 or later, so newer operations should make sure the query process is part of hiring from the start.

The Clearinghouse controls to check

• Complete a full pre-employment query before a newly hired driver performs Part 382 safety-sensitive functions
• Query each covered driver at least once within the required annual period
• Obtain the correct consent for the type of query being run
• If a limited query shows that information exists, complete the required full query within the applicable timeframe
• Make employer reports to the Clearinghouse when Part 382 requires them
• Keep the employer’s Clearinghouse registration and C/TPA permissions current

Employers purchase their own Clearinghouse query plan even when a C/TPA conducts queries for them. The Clearinghouse retains the employer’s query history, so employers generally do not have to maintain separate copies simply to satisfy the Clearinghouse query-record retention requirement.

A driver with a prohibited status cannot perform safety-sensitive functions. Returning requires the DOT return-to-duty process, including evaluation by a qualified substance abuse professional, completion of the SAP’s prescribed education or treatment, SAP follow-up evaluation and a negative directly observed return-to-duty test. Follow-up testing continues afterward as directed by the SAP. You can review the rule text in Part 382).

What to settle before choosing a provider

Establish exactly what the provider is responsible for. Ask whether it will be designated as your C/TPA, whether it will conduct queries, whether it administers your testing consortium, and who monitors annual query due dates and prohibited-driver notifications.
