Every year on August 5th, International Traffic Light Day highlights the importance of the traffic light. It’s also a day that commemorates the installation of the first traffic signal system.
The world’s first electric traffic signal was installed on August 5th,
1914 in Cleveland, Ohio. The traffic signal was placed on the corner of
Euclid Avenue and East 105th Street. Some people dispute the location of
the world’s first traffic light. In 1868, a traffic device in London
helped people know when to stop and when to use caution. In 1912, a
police officer in Salt Lake City, Utah installed a wooden box with red
and green lights onto a pole.
