Cost Per Mile to Operate a Truck in Louisiana (2026)
What it actually costs owner-operators to run a semi-truck in Louisiana — diesel, insurance, IFTA, and freight market notes for LA.
Diesel prices in Louisiana
The average diesel price in Louisiana is roughly $3.50/gal. For a truck running 8,000 miles/month at 6.5 MPG, that's about $4,308/month in fuel alone — or roughly $0.54/mile. Fuel is typically 30–40% of total cost per mile, so Louisiana's diesel price has a major impact on whether a load is profitable.
Trucking insurance in Louisiana
Louisiana insurance is high — $12,500–$17,000/yr due to litigation climate. Annual premiums vary widely based on CDL history, equipment age, and operating radius.
LA IFTA and fuel taxes
Louisiana IFTA fuel tax: 20¢/gal diesel. File quarterly and keep accurate trip mileage records by jurisdiction to stay compliant.
Freight market in Louisiana
Port of New Orleans, petrochemicals, and Gulf oilfield freight.
