Traffic lights

Traffic lights are used to help organize the flow of traffic. Generally, a red light means “stop,” a yellow light
means “caution” and a green light means “go.” These signals can have slightly different meanings if they are
flashing or if they are shaped as arrows rather than circles. In some places green arrows may flash; in others they
may not.

Steady red — stop — Steady green — continue Steady yellow — slow Flashing red — stop,
after coming to a full stop, if the intersection is clear down and stop before then continue only
you may turn right or turn the intersection unless when it is safe

unless a sign forbids it time
