Oregon Traffic Laws and Rules of the Road
Domain overview
Oregon's traffic-law domain checks whether you can teach statutes accurately and connect each rule to a real driving decision. Expect items on default speed limits, crosswalk and right-of-way duties, signal timing, child restraints, and the school-bus and Move Over rules.
Speed and the basic speed rule
Oregon's basic speed rule (ORS 811.100) requires a speed that is reasonable and prudent for conditions; the posted number is a ceiling, not a target. Where nothing is posted, know the defaults: 15 mph in alleys, 20 mph in school zones, 25 mph in business and residential districts, 55 mph on open rural roads, 65-70 on rural interstates where signed. Speeding and "too fast for conditions" are separate violations, and wet Oregon pavement is where the second one catches new drivers.
Right-of-way, crosswalks, and protected users
- Yield to a pedestrian in a crosswalk, marked or unmarked, at an intersection; a painted line is not required.
- Unprotected left turns yield to oncoming traffic; right on red is legal after a full stop unless a sign prohibits it.
- Stop for a school bus with red lights flashing on an undivided road; on a divided highway, opposing traffic separated by a median is not required to stop.
- Move Over: on multi-lane roads, change lanes away from stopped emergency, tow, or roadside-assistance vehicles with lights; if you cannot, slow down.
Signals, devices, restraints
Signal at least 100 feet before a turn or lane change. Handheld phone use is illegal for every driver; drivers under 18 may not use any mobile device, hands-free included. Safety belts are primary enforcement; children under 8 (or under 4'9") need an appropriate child seat, and rear-facing is required for children under 2.
Worked example
A student drives a 25 mph residential street at 8 a.m. and sees a SCHOOL 20 sign. The correct chain: the sign sets a 20 mph maximum during the posted hours, the basic speed rule still applies if children are present, and the student must be ready to stop for a pedestrian in the unmarked crosswalk at the next corner.
Traps
Assuming a crosswalk must be painted; treating the school-zone number as the only rule; ignoring the split between "over the limit" and "too fast for conditions"; forgetting that Oregon's under-18 device ban includes hands-free calls.
