What is a pink slip for an automobile?

A pink slip is a piece of paperwork that is required to prove the ownership of a vehicle in Canada and the United States. A pink slip is also known as a vehicle title.

The pink slip provides information about the vehicle, such as the year, make and model of the vehicle, its license plate number and technical information about the vehicle to determine its taxation regime.

Vehicle titles are not necessarily pink, as implied by the informal term "pink slip." In California, vehicle titles were once pink, but now come in many different colors, such as blue, green, yellow or teal with purple or blue borders.
