It is a criminal offense to drive around in a dirty car in Russia (Because It may impair visibility for driver and identification of the vehicle).
If you are ever driving in Russia and forget to keep your car clean, chances are that you will be stopped by the police and fined. An on the spot fine of up to 500 roubles can be levied if you are caught driving a dirty car. Exactly how dirty is 'dirty' is, however, open to interpretation.
A survey conducted by a Russian newspaper revealed that 46 percent of the general public thought that a muddy license plate meant that the car was dirty. 22 percent said that cars that had 'wash me' written on them are the ones that need to be penalized. But a good 9 percent of the people were bent upon their stand that as long as the driver of the car was visible, the car should not be considered as dirty.
