Semi / Dry Van Costs in Washington

Diesel fuel in Washington currently averages $5.36 per gallon, which includes a state fuel tax of 49.4¢ 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 Washington runs approximately $486/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.

Washington's high fuel tax (49.4¢/gal) and Puget Sound traffic congestion can increase per-mile costs. The state has no income tax, benefiting owner-operator take-home. Seattle-Tacoma port freight drives strong drayage demand.

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.
