With rising pollution in Paris, it has had to institute a driving ban, the first in the past 40 years. People will only be allowed to drive their cars on alternate days. The first day, all cars with even numbered license plates were fined, except if they had three or more passengers, if it was a government car, and those with foreign plates. Public transportation was free. After a week with this new rule in place, the pollution had already lowered a drastic amount, and officials predicted that in a few weeks they would be at almost normal levels. With a certain weather pattern lately, pollution settled over 30 European cities. By 10:30 the first day, over 3,000 even numbered cars had been stopped.
