KYU Guide
Understanding the Kentucky Weight Distance (KYU) Tax
KYU stands for Kentucky Unified Carrier. A KYU number is required for certain motor carriers operating vehicles over 59,999 lbs so the carrier can report taxable mileage under Kentucky's weight distance tax program.
If you regularly move freight through Kentucky, you typically need to maintain a KYU account and file on the state's quarterly schedule. If your trips are more occasional, a Temporary KYU Permit for a limited, trip-specific window may let you stay compliant without completing full registration.
Accurate records matter — especially mileage, vehicle unit information, and required documentation — so your filings match the units you operate.

Weight Limits
Kentucky Truck Weight Limits & KYU Requirements
In Kentucky, the maximum legal weight for a single vehicle is 80,000 lbs on the interstate system. Trucks over 59,999 lbs must obtain a KYU number.
Heavier Loads
May need additional Kentucky permits beyond KYU, depending on route and vehicle configuration.
KYU vs. IRP/IFTA
KYU is separate from IRP plate registration and IFTA fuel reporting — carriers often manage all three programs.
Record Keeping
Solid mileage records make quarterly tax filing faster and significantly reduce audit risk.
