Red — Stop in front of the marked crosswalk or, if there’s no marked crosswalk, before the sidewalk out of the way of pedestrians and vehicles. Unless a sign shows otherwise or vehicle/pedestrian traffic does not permit, you may, after stopping completely, turn right. You may also turn right or left from a one-way street to another one-way street.
Amber — An amber light is a warning that the light is going to turn red. Slow down and stop — never accelerate to “make the light.” If you’re already in the intersection when the light turns amber, continue through.
Green — You may proceed, but you must yield the right-of-way to pedestrians in the crosswalk and to other vehicles already in the intersection. To turn left, you may enter the intersection on a green light, but you must yield to pedestrians and oncoming traffic. You may have to complete the turn during an amber or red light.
Flashing Red — Come to a complete stop, proceeding only when safe.
Flashing Amber — Slow down and be prepared to stop. You must yield the right-of-way to pedestrians.
Amber Arrow — A steady amber arrow may be shown after a green arrow. The amber arrow is a warning that oncoming traffic may next receive a green signal. Slow down and stop. If you’re already in the intersection when the amber signal appears, continue and complete your turn.
Green Arrow — You may proceed only in the direction of the arrow, either steady or flashing, providing you’re in the proper lane.
Flashing Green Left-Arrow — You may proceed only to make a left turn, unless facing another signal that indicates other movements are allowed. (Flashing leftarrows may be shown together with steady red, amber or green lights.)
Green U-Turn Arrow — You may proceed to make a U-turn after yielding to pedestrians and other vehicles already in the intersection.
Green Left-Arrow with Red Light — When a green left-arrow is shown with a red light together you may proceed and make a left turn only. It’s illegal to make a right turn at an intersection when a green left-arrow is shown with a red light, even if there’s no sign indicating a right turn is prohibited on a red light. Under no circumstances are you allowed to turn right or drive straight through when a green left-arrow is illuminated with a red light. If a green left-arrow is illuminated alone (the red light is not on) you may turn right if it’s safe to do so and no sign prohibits it.
