International Traffic Light Day

International Traffic Light Day - August 5

International Traffic Light Day calls to pay attention to the importance of traffic lights in everyday life. These devices have greatly simplified and made road traffic safer – now we cannot imagine a single long car trip without them. Such useful things deserve a separate holiday.


The first traffic light in US history was installed on August 5, 1914 in Cleveland. Its predecessor is the 1868 London traffic light prototype. For a long time, the traffic light had only two colors: red and green, and the warning function was performed by a sound signal. The growth in the number of cars and the increase in traffic density quickly created the need for new traffic lights. In 1920, a yellow signal appeared, which is used in devices to this day.

To effectively regulate traffic, a sufficient number of traffic lights is not enough: it is necessary that their signals are synchronized, and also not too long or short. This is not an easy task, which in many densely populated cities cannot cope.

Interesting facts

  • Japanese traffic lights used blue instead of green for a long time.
  • Most traffic jams in major cities in India.
  • The idea of ​​combining color and sound signals is coming back again, as it is convenient for people with visual impairments.
  • In Rio de Janeiro, drivers don’t have to stop when they see a red signal at night. This is due to the fact that a stopped car can be robbed, because the country has big problems with crime.
