Always stop at red light.

Japan has the bluest green lights in the world. From my understanding this is because when the legislature for traffic lights was written, "Ao" was still used for both blue and green colors. Then later a new word for green was invented/implemented and Ao started being used only for blue. But instead of changing the legislature they changed the tint of the traffic lights to as close to blue as international treaties would allow.
