Traffic jams are one of the reasons of pollution

• No one will be surprised to learn that areas with the largest number of cars on the road see higher levels of air pollution on average. Motor vehicles are one of the largest sources of pollution worldwide. You may be surprised to learn, however, that slower moving traffic emits more pollution than when cars move at freeway speeds. Traffic jams are bad for our air.

• In traffic jams, or at red traffic lights with other vehicles stationary in front, research has shown that if we close the car windows and switch off the fan, this gave us the lowest exposure to pollutants. It is also safe to put fans onto the setting where they re-circulate air within the car without drawing polluted air in from outside.
