Semi / Dry Van Cost Per Mile in Connecticut

Diesel fuel in Connecticut currently averages $5.24 per gallon, which includes a state fuel tax of 43.2¢ per gallon. This is one of the higher fuel tax rates in the country, making fuel cost an outsized portion of your semi / dry van CPM.

Average commercial semi / dry van insurance in Connecticut runs approximately $476/month. This moderate premium is typical for the region and should be reviewed annually to ensure you're not overpaying.

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.

Connecticut's position between New York and Boston creates dense freight demand but also heavy congestion on I-95. High fuel taxes and toll costs on the Merritt and Wilbur Cross Parkways add to operating expenses.

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.
