State-specific factors below. ## Delaware-specific costs Diesel fuel in Delaware currently averages $3.65 per gallon, which includes a state fuel tax of 22.0¢ 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 Delaware runs approximately $420/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. Delaware's I-95 corridor carries heavy Northeast freight traffic. The state's lack of sales tax attracts distribution centers, creating consistent local/regional freight demand. Delaware Memorial Bridge tolls apply to southbound crossings. 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. ## Delaware Semi / Dry Van FAQs **How much does it cost to operate a semi in Delaware?** A semi costs about $1.96 per mile to operate in Delaware in 2026, based on local diesel at $3.65/gallon and average commercial insurance near $420/month.

Add maintenance ($0.25–$0.40/mi) and tolls ($0.05–$0.10/mi). 3. **Divide fixed costs by miles driven.** Total monthly fixed cost ÷ monthly miles. At 11,500 miles/month, expect $0.90–$1.25 in fixed cost per mile. 4. **Add variable + fixed for operating CPM.** Operating CPM = variable + fixed. Add desired weekly take-home divided by weekly miles to get your minimum acceptable rate per mile. ## Frequently asked questions ### What is the average cost per mile for a semi truck? Semi truck operating cost per mile averages $1.75–$2.45 in 2026, with the American Transportation Research Institute pegging the industry marginal cost at roughly $2.27/mile.
