If you haul freight for hire in Washington, you need commercial truck insurance. Seattle and Tacoma together form the fourth-largest container gateway in the U.S., while Spokane anchors distribution across the Inland Northwest. Your required limits depend on your truck's weight, your cargo, and whether you run interstate or intrastate.
