Minnesota employers with drivers covered by Part 382 need a full FMCSA Drug and Alcohol Clearinghouse query before allowing a new driver to perform a safety-sensitive function, plus a query on each covered driver at least once a year. Employers also have reporting duties when certain drug and alcohol violations occur. A designated C/TPA can handle queries and certain reporting functions on the employer’s behalf.

Who in Minnesota needs Clearinghouse queries

Our carrier directory lists about 76,110 motor carrier records with a Minnesota address. About 59,300 are marked intrastate-only and about 48,370 are private carriers. Many are contractors, distributors, farms and other businesses that employ CDL drivers even though transportation is not their main business.

Part 382 generally covers drivers who operate vehicles requiring a CDL or CLP in commerce, including covered intrastate operations. Whether an agricultural operation is covered depends on the vehicle, the driver’s CDL requirements and any exemption that applies. Farm operators should confirm that position before leaving drivers outside the testing and Clearinghouse program.

School bus, charter and motorcoach employers

Minnesota has about 4,810 records listing passenger vehicles. School bus contractors, charter operators and other passenger employers can have concentrated hiring periods, making it important to complete the required steps before a new CDL driver performs safety-sensitive work.

A pre-employment Clearinghouse check is a full query. The driver gives specific electronic consent through the Clearinghouse before the employer can view the detailed result. The employer must receive the required result before allowing the driver to perform a safety-sensitive function.

The annual query and one-truck owners

Each covered driver must be queried at least once each year. An employer can use a limited query for the annual requirement if it has the driver’s general consent. If the limited query shows that information exists, the employer must conduct a full query within 24 hours. If that full query is not completed within 24 hours, the driver cannot continue performing safety-sensitive functions until the required query is completed and the result allows the driver to work.

About 40,840 Minnesota records list a single power unit. An owner-operator who employs himself or herself as a CDL driver must designate a C/TPA in the Clearinghouse. The rule text is in [49 CFR Part 382]\(https://www.ecfr.gov/current/title-49/subtitle-B/chapter-III/subchapter-B/part-382).

What to ask before you designate a provider

  • Will you act as my C/TPA and run pre-employment and annual queries?
  • Which Clearinghouse reports will you handle on my behalf?
  • How quickly do you return query results during a hiring rush?
  • Can you arrange DOT collections near my drivers?
  • What support do you provide if a driver is in prohibited status?

About 6,610 Minnesota records first registered with FMCSA in 2025 or later. A new employer using CDL drivers should have its testing and Clearinghouse processes in place before those drivers begin safety-sensitive work.

DOT compliance questions for Minnesota

Do school bus drivers in Minnesota need Clearinghouse queries?

Generally yes if the driver operates a vehicle requiring a CDL and is subject to Part 382. Government and school-related operations can have different regulatory arrangements, so confirm coverage if another DOT testing rule or a specific CDL exception may apply.

I farm and haul my own grain. Does the Clearinghouse apply to me?

It depends on whether the driver is required to hold a CDL or CLP and whether a farm-related CDL exception applies. Review the actual vehicles and operation before assuming the driver is exempt.

Can I run annual queries for all my drivers on one date?

Yes, provided each covered driver is queried at least once each year and you do not allow the required interval to lapse.

Does it matter where the provider is based?

Not for the Clearinghouse query itself, which is handled online. If the provider also manages testing, confirm that it can arrange suitable collection sites where your drivers operate.

How much does Clearinghouse support cost?

Pricing varies by provider, driver count and the services included. Ask whether the price includes C/TPA administration, queries, reporting and any separate drug and alcohol testing program services.
