Kentucky KYU Permit FAQ

Quick answers for dispatchers, owner-operators, and safety managers navigating Kentucky weight distance requirements.

Kentucky requires motor carriers over 59,999 lbs to hold KYU credentials. Interstate highways typically enforce an 80,000 lb gross weight limit unless additional permits apply.

Why FAQ Matters for Your Fleet

Kentucky weight distance tax funds highway maintenance. The KYU program tracks carriers that operate heavy trucks on state roads and ensures mileage is reported each quarter through Form KYU-100.

Whether you are an interstate carrier passing through Louisville or a regional fleet with daily Kentucky miles, the right KYU path — full registration or a temporary 10-day permit — keeps you legal at weigh stations and during audits.
