Trucking in Oregon
Oregon is unique in American trucking. It is the only state that charges a weight-mile tax instead of diesel fuel tax for trucks over 26,000 lbs. Every mile you drive in Oregon is taxed based on your declared weight — currently across 85 rate tiers, though recent legislation is simplifying the system to 10. Oregon does not participate in IFTA for vehicles over 26,000 lbs because the weight-mile tax replaces it. If you run heavy loads through Oregon without understanding this system, you will get a bill you did not expect.
The terrain demands equal attention. Cabbage Hill on I-84 eastbound drops 2,000 feet in 6 miles at a 6% grade with a double hairpin turn. Out-of-state drivers account for 78% of CMV crashes here, and 59% of those crashes are caused by brake failure. Start your descent in low gear at milepost 270, check your brakes at the weigh station at milepost 227, and respect the speed advisory signs that recommend as slow as 18 mph. Escape ramps sit at mileposts 220 and 221 for those who wait too long. Oregon’s chain law is more aggressive than Idaho’s — statewide activation including conditional road closures that require all vehicles to chain up.
Oregon requires insurance filing with the Commerce and Compliance Division before you operate on state highways. Not after. Carriers who show up in Oregon without filed insurance face immediate enforcement. The intrastate for-hire minimum is $750,000 CSL — already higher than most states require. Given the severity of Cabbage Hill corridor accidents and Portland metro congestion, $1M is the responsible floor. The Green Light preclearance program has saved carriers over 2 million hours and is now interoperable with PrePass and Drivewyze at 21 facilities statewide.
