Cost Per Mile to Operate a Truck in Kentucky (2026)
What it actually costs owner-operators to run a semi-truck in Kentucky — diesel, insurance, IFTA, and freight market notes for KY.
Diesel prices in Kentucky
The average diesel price in Kentucky is roughly $3.55/gal. For a truck running 8,000 miles/month at 6.5 MPG, that's about $4,369/month in fuel alone — or roughly $0.55/mile. Fuel is typically 30–40% of total cost per mile, so Kentucky's diesel price has a major impact on whether a load is profitable.
Trucking insurance in Kentucky
Kentucky insurance averages $10,000–$13,000/yr. Annual premiums vary widely based on CDL history, equipment age, and operating radius.
KY IFTA and fuel taxes
Kentucky IFTA fuel tax: 21.6¢/gal diesel + KYU weight-distance tax. File quarterly and keep accurate trip mileage records by jurisdiction to stay compliant.
Freight market in Kentucky
Louisville is UPS Worldport hub — air-truck transfer drives huge nightly freight volume.
