Drivers of semi-trucks and tractor-trailers can find economic opportunities in several of Oregon’s economic sectors. Agriculture is a key economic sector, producing wheat, potatoes, fruits (including wine grapes), vegetables, and nursery and greenhouse products. Semi-trucks transport these products to distribution centers and markets across the country and internationally. Although the timber industry has declined in recent decades, the state remains a leading producer of softwood lumber, creating a need for truck drivers experienced in transporting raw timber and wood products. Oregon’s manufacturing industry produces machinery, high-tech equipment, and electronics. These industries depend on truckers to deliver materials to them as well as transport their products. Finally, the Port of Portland, including Oregon’s only deep-draft container port, needs truckers experienced in intermodal transport.

As a big rig driver, however, you may have to drive with extreme caution through much of Oregon in the wintertime. Western Oregon can be rainy, resulting in slippery roads and lower visibility. Also, the Siskiyou Pass is one of the most dangerous sections of road on Interstate 5. This mountain pass has a 6 percent downgrade on six miles of winding, often foggy, snowy, or icy road with sharp curves. Interstate 84, U.S. Route 20, and State Route 58 can also become treacherous under conditions of ice or snow.
