Semi / Dry Van Cost Per Mile in Louisiana

Diesel fuel in Louisiana currently averages $4.83 per gallon, which includes a state fuel tax of 20.0¢ per gallon. This relatively low fuel tax helps keep your semi / dry van fuel cost per mile below the national average.

Average commercial semi / dry van insurance in Louisiana runs approximately $610/month. This above-average premium means insurance is a larger-than-usual share of your fixed costs — reducing deadhead miles and maximizing utilization becomes even more critical to keeping CPM competitive.

Semi trucks average 5.5–7.5 MPG, making fuel the largest single expense — typically 30–40% of total CPM. At these consumption rates, even a $0.20/gallon price difference between states changes your CPM by $0.03–$0.04/mile, which compounds to $300–$450/month at 11,500 miles.

Louisiana has the highest average commercial insurance rates in the country. The legal environment and high litigation rates drive premiums well above the national average, making insurance optimization essential for CPM control.

Semi insurance premiums are the highest of any equipment class, reflecting the higher liability exposure and cargo values. Tire costs ($0.04–$0.06/mile), DEF fluid, and DPF maintenance add meaningful variable costs that lighter equipment classes don't face.
