Traffic signals and pavement markings must be obeyed unless a police officer directs otherwise. A driver may never leave the roadway to avoid a traffic signal. At some intersections, however, there may be a single red or yellow light.
Some traffic lights are steady, some flash and some are arrows.
When traffic control signs are not working, you must always come to a full stop. These lights may be red, yellow or green. Stop at the marked stop line. If there is not a marked stop line, stop before entering the crosswalk. If there is no crosswalk, stop before entering the intersection.
