The meaning of the lights of traffic lights is the following:

 

A) A non-flashing red light, in the form of a motionless pedestrian, indicates to pedestrians that they should not start crossing the road.

 

B) A green non-flashing light, in the form of a moving pedestrian, indicates to pedestrians that they may begin to cross the roadway. When said light goes on intermittent, it means that the time they still have to finish crossing the road is about to end and that the red light will turn on.
