Some cars are seen on the oldest Hungari

Some cars are seen on the oldest Hungarian bridge ‘Lanchid’ (Chain Bridge) in Budapest downtown on January 11, 2009. Gabor Demszky, the mayor of Budapest announced new traffic restrictions to reduce high pollution levels, prompted by major industries switching to oil consumption during the current gas shortage. Cars with odd-numbered car plates will only be allowed to drive on odd calendar days and cars with number plates ending with an even number will have even days.
