What Is a Kentucky Weight Distance (KYU) Permit?
What Is the Kentucky Weight Distance Tax?
The Kentucky Weight Distance Tax (KYWD), commonly referred to as the KYU permit, is a state tax program that applies to certain commercial motor vehicles operating on Kentucky highways. It is based on the weight of the vehicle and the distance traveled within the state. Kentucky uses the revenue to maintain roads and infrastructure used by heavy trucks.
Who Does It Apply To?
Generally, the Kentucky Weight Distance Tax applies to motor carriers operating vehicles with a gross vehicle weight (GVW) or gross combination weight (GCW) of 60,000 pounds or more. This includes:
- Interstate and intrastate commercial trucking operations
- Owner-operators and fleet operators
- Vehicles that travel on Kentucky public highways, including those just passing through the state
If your vehicle is registered at or above this threshold and you run in Kentucky, you will typically need a KYU account number and must comply with reporting and tax obligations.
How Does the KYU Permit Work?
After registering for a KYU account with the state, you receive a KYU number that identifies your operation. You must then:
- Report taxable miles driven in Kentucky (usually on a quarterly basis)
- Pay the weight distance tax based on those miles and your vehicle weight
- Keep records to support your reported mileage
Failure to register when required or to file and pay on time can result in penalties, interest, and possible enforcement action at weigh stations or ports of entry.
Why Compliance Matters
Staying compliant with Kentucky’s Weight Distance Tax helps you avoid fines and operating restrictions. Many carriers rely on a compliance partner to handle KYU registration, quarterly filings, and any notices from the state. If you’re unsure whether you need a KYU permit, a quick review of your vehicle weights and Kentucky travel can clarify your requirements.
