Oregon Truck Lane Restrictions
Oregon puts campers, trailers, and any vehicle registered at 10,000 pounds or more in the right lane on every road with two or more lanes your way (ORS 811.325). Not just interstates, any multilane road. You can move left to pass, turn left, handle an emergency, or dodge merging traffic. It's a Class B violation: presumptive fine $265, up to $1,000, and it doubles in a work or school zone.

Roads, exceptions, and signs
- Where it applies: Statewide, on every roadway with 2+ lanes moving your way, not just interstates.
- Statutory. You'll also see 'Slower Traffic Keep Right' and truck-lane signs on grades, but the weight rule is written into the code.
- General rule: Oregon also has a general drive-on-the-right rule for all traffic (ORS 811.315), and slower traffic keeps right.
- Trigger is 2+ lanes each way (broader than the 3+ lane trigger in Washington), and it explicitly names campers and trailers alongside 10,000-lb vehicles.
What a lane violation costs
Class B traffic violation. Presumptive fine $265; range runs from a $135 minimum up to $1,000. It doubles in a work or school zone.
