You are stopped at a red light and want to turn right. A NO TURN ON RED sign is posted. In front of the white stop line is a green painted box with a bicycle symbol. What must you do?

Correct answer: Wait behind the white stop line until the light is green and the box is clear

Why

The box puts bicyclists in front of cars, where drivers can see them before the light turns green. When the light turns green, check for bicyclists who go straight or into the bike lane before you turn right; this prevents right-hook crashes. Washington law allows a right turn on red after a full stop unless a sign forbids it, and the guide tells drivers not to turn right on red near a bicycle box.
