Car-free days

On car-free days, people are encouraged either through state policy or by societal consensus to travel by means other than cars. Some cities, like Jakarta and Tehran, have weekly car-free days. Other such days are annual. World Car Free Day is celebrated on September 22. Organized events are held in some cities and countries. In Israel, the holiday of Yom Kippur is regarded as a car free day through societal consensus without official policy enforcement.

The events, which vary by location, give motorists and commuters an idea of their locality with fewer cars. The concept dates from the 1970s but was popularised in the 1990s. Tel Aviv has had a car free day due to Yom Kippur since 1935.

Currently Bogotá holds the world's largest car-free weekday event covering the entire city. The first car-free day was held in February 2000 and became institutionalised through a public referendum.
