Semi / Dry Van Cost Per Mile in Florida

Diesel fuel in Florida currently averages $5.06 per gallon, which includes a state fuel tax of 36.2¢ per gallon. This fuel tax is near the national average and should be factored into your semi / dry van rate calculations.

Average commercial semi / dry van insurance in Florida runs approximately $577/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.

Florida's hurricane season (June–November) can spike insurance rates and disrupt freight patterns. Year-round demand from port activity (Jacksonville, Miami, Tampa) and consumer goods keeps base rates competitive.

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.
