What Is a Kentucky Weight Distance Permit?

The Kentucky Weight Distance Tax (KYWD), commonly referred to as the KYU permit, is a state requirement for certain commercial vehicles operating on Kentucky highways. It applies to vehicles registered at 60,000 pounds or more and requires carriers to report taxable miles driven within the state.

Carriers must obtain a Kentucky KYU account number before operating qualifying vehicles in Kentucky.

Who Is Required to Obtain a KYU Number?

You are generally required to obtain a KYU permit if:

Your vehicle is registered at 60,000 lbs or greater
You operate commercially in Kentucky
Your vehicle travels taxable miles within the state
You are an out-of-state carrier entering Kentucky

This requirement applies to both Kentucky-based and interstate carriers.

If your vehicle is registered under 60,000 pounds, the Weight Distance Tax typically does not apply.

KYU Registration Requirements

To complete Kentucky Weight Distance registration, carriers must provide:

Legal business name and entity details
Federal EIN or SSN (for sole proprietors)
Business address and contact information
Vehicle registration weight details
Supporting documentation as required

Accurate information is critical. Errors can delay approval or create compliance issues.

Temporary KYU Permit

Carriers making occasional trips into Kentucky may require a temporary KYU permit instead of full account registration. Temporary permits allow limited operation while ensuring compliance with Kentucky weight distance rules.

Quarterly Filing Obligations

Carriers with a KYU number must:

Track miles driven in Kentucky
File quarterly weight distance tax returns
Pay applicable tax based on reported mileage

Late or incorrect filings may result in penalties and interest.

Maintaining Compliance

Once registered, carriers are responsible for:

Keeping accurate mileage records
Filing returns on time
Updating the state regarding business or vehicle changes
Responding promptly to notices from Kentucky authorities

Failure to maintain compliance can result in assessments or operational restrictions.
