Parking violation
A parking violation occurs when a motor vehicle is parked in a restricted or unauthorized location. It is illegal to park in the middle of a highway or road, but parking on the sides may be allowed with restrictions. Violations are typically documented with a traffic ticket issued by a police officer or government official.
Parking ticket fines generate revenue for municipalities and can also aid in criminal investigations. For instance, the NYPD used a parking ticket on serial murderer David Berkowitz's car to help identify and arrest him, leading to the capture of the notorious serial killer known as "The Son of Sam".
