Let's say a bicyclist up ahead has already pushed the button and a green bike symbol appears. If I am also a bicyclist and come up to the intersection while it's still green, do I need to stop first (since there is a stop sign) and then proceed through the green light, or can I ignore the stop sign and zoom on through?
