Intersections and turns1 of 2
Under Oregon law, how far in advance must you signal before making a turn or changing lanes?
The answer
Answer: A. Oregon law requires drivers to signal continuously for at least 100 feet before turning or changing lanes. Signaling alerts pedestrians, bicyclists, and other drivers of your intention so they can adjust their speed and position safely. Check your side mirrors and blind spots carefully before beginning the turn or moving into the adjacent travel lane.
