American citizens know that the cars driven throughout America is polluting the air. Not just the cars in U.S but cars all around the world. Residents on Vauban in Germany, Paris, Bogota and even the USA cars are reduced from bieng driven or they had been banned to reduce the pollution from the air. They dont want to turn out like China, which is know as one of the most polluted cities in the word.

For that day there isn't any traffic because all of the residents are hiking, biking, skating or taking the bus to work. This car-free day reduce smog and if any person violats that day they are going to be fine $25. They said its a good way to take away stress and lower pollution.
