WHAT IS THE USAGE AIM OF TRAFFIC LIGHTS
Vehicles and people are so important in traffic
because all of thems actions effect the other
one. Each one must guess to others action and
act according to it. It is too difficult of
course.
Traffic signs help to guess other actions. for
example if red light is turn on we know that
vehicles are stopped or if a car give right
signals we know that it turns to right from the
next crossing.
Traffic is rid of ambiguity by the signs , we
take cautions for against dangers.
Traffic signs are the common language for
drivers and pedestrians. So everbody must learn
and apply this language for the traffic safety.
