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.

Where are traffic lights controlled from?

A traffic signal is typically controlled by a controller mounted inside a cabinet. Some electro-mechanical controllers are still in use (New York City still had 4,800 as of 1998, though the number is lower now due to the prevalence of the signal controller boxes). However, modern traffic controllers are solid state.
