A bike box is used at intersections to designate a space for cyclists to wait at a red light. Cyclists stop in front of motorists and can proceed through the intersection first when the light turns green. Right turns on red lights are generally not permitted in these intersections, unless a sign is posted with an exception. These areas increase cyclist visibility and reduce the risk of “right hook” collisions after a green signal.
Bike boxes are green areas on the road containing a white bicycle symbol. A section of green bicycle lane often precedes the box."
