Traffic lights tell us when to stop, when to turn, and how to maneuver through an intersection.

Signals

Blank traffic lights

During an electrical power loss, traffic lights at intersections will not work. Yield the right-of-way to vehicles in the intersection and to vehicles entering the intersection from your right.

Pedestrian signalsAt intersections with traffic lights where there are no pedestrian

signals, pedestrians facing a green light may cross.

Pedestrians may not cross on a flashing green light or a left-turn green arrow.

Where there are pedestrian pushbuttons, a pedestrian must use the button to bring on the walk signal.

You must observe, obey the traffic rules and use safe driving

skills to drive through these intersections.
