Under both Washington and
Oregon law, you can turn right on a solid red arrow (the same as a solid red light) provided you come to a full stop, traffic is clear, and it's safe to do so,
unless there's a sign posted that prohibits it. That's true even in situations where there are two lanes turning right. It's also OK to turn left on a red arrow when you're turning onto a one-way street.
Turns on red require an extra dose of caution. You'll want to double check for bicyclists and pedestrians who may not be expecting your turn.
And if you encounter a (fairly rare) flashing red arrow? Treat it the same as you would a stop sign.
