What is the difference between Traffic Signs and Traffic Signals?
Traffic signs can only display one piece of information and they are normally not illuminated. Traffic signs are usually put on posts on the side of the road and tell you to stop, yield, or what the speed limit is. Traffic signals have a series of lights (usually Red, Yellow, and Green), which change to give motorists multiple directions. Traffic signals are usually placed in intersections, and aside from telling drivers to go and stop, can also flash arrow signals to tell drivers in a turning lane when to make a turn.
