What Is a KYU Permit?

A KYU permit is a highway use tax number issued by the Kentucky Transportation Cabinet for commercial vehicles operating in Kentucky. It applies to vehicles that:

  • Operate on Kentucky highways

  • Have a gross vehicle weight (GVW) of 26,001 pounds or more

  • Are used for interstate or intrastate commerce

The KYU system ensures that commercial vehicle operators pay taxes based on highway usage rather than only fuel taxes.

 Do Owner-Operators Need a KYU Number?

The short answer: it depends on your vehicle weight and operations.

Vehicle Weight

  • If your vehicle’s GVW is under 26,001 lbs, you generally do not need a KYU number.

  • If your vehicle’s GVW is 26,001 lbs or more, a KYU number is required.

 Type of Operation

  • Owner-operators running solo or small fleets must register if they transport goods or passengers commercially within Kentucky and meet weight requirements.

  • If you operate exclusively intrastate and your vehicle is below the weight threshold, KYU may not be necessary.

Out-of-State Owner-Operators

  • If you are based in another state but regularly operate in Kentucky, you must obtain a KYU number if your vehicle meets the weight threshold.

  • Even single-owner vehicles hauling into Kentucky temporarily may require a KYU permit or temporary authorization.

  2. Provide Vehicle and Business Information – Include USDOT number, license plate, and GVW.

  3. Calculate Highway Use Tax – Based on vehicle weight and miles traveled in Kentucky.

  4. Pay Applicable Fees – Annual registration fees are required.

  5. Receive KYU Permit – Display the KYU decal on your vehicle as required.

 Compliance Tips for Owner-Operators

  • Always carry your KYU permit or registration proof in your vehicle.

  • Keep accurate mileage logs for tax reporting.

  • Renew your KYU registration annually to avoid penalties.

  • Check if temporary permits apply for short-term operations in Kentucky.

 Summary

Owner-operators in Kentucky must obtain a KYU permit if:

  • Their vehicle GVW is 26,001 lbs or more, and

  • They operate commercially within or into Kentucky

Smaller vehicles or private-use trucks are typically exempt. Obtaining a KYU number ensures compliance with Kentucky highway tax laws and prevents costly penalties.
