A parking violation is the act of parking a motor vehicle in a restricted place or in an unauthorized manner. It is against the law virtually everywhere to park a vehicle in the middle of a highway or road; parking on one or both sides of a road, however, is commonly permitted. However, restrictions apply to such parking, and may result in an offense being committed. Such offenses are usually cited by a police officer or other government official in the form of a traffic ticket.[from wikipedia]

Signage is the design or use of signs and symbols to communicate a message.[from wikipedia]
