Police Vehicles in The United States and Canada - Markings and Appearance

Markings and Appearance

North American police cars were once noted for being painted black and white, with the car doors and roof painted white, while the trunk, hood, front fenders and rear quarter panels were painted black. The fleet vehicles that were used typically came painted in a single color, most commonly white or black, from the factory and were used as such. The contrasting black or white color was added to make the vehicle stand out from civilian vehicles. In 2007, the Ontario Provincial Police (OPP) began converting its fleet back to a black-and-white scheme after decades of using other colours.

Beginning in the 1970s, police vehicle markings have become increasingly stylistic, with widespread use of computer-graphics and vinyl striping. While black and white designs are still in use in many jurisdictions, cars may range from being all white to completely black. Blues and greens of various hues are also frequently used. Brown, beiges and tans are favored by rural police and sheriff's offices.

Official markings also vary by jurisdiction. The side doors and sometimes the hood of a marked police car usually bear the agency's badge or the city seal, often in reflective finish. Markings such as emergency telephone numbers, generic anti-drug or anti-crime messages, or even website URLs are also common. Some agencies also have identification numbers printed on the roofs of patrol cars for tracking from aircraft, or to distinguish specialized units, such as K-9 units or supervisors.

Currently, in the United States, the paint scheme for each fleet is determined either by the individual agency or by uniform state legislation as in Minnesota. Usually, state laws exist that establish standards for police vehicle markings, and proscribe civilian vehicles from using certain markings or paint schemes as is the case in California.

Today, most fleet markings on patrol vehicles are created from reflective vinyl with an adhesive backing that is applied in a peel-and-stick manner. Colors chosen to represent the departments identity are typically chosen by the individual department, although, as noted above, some states have specific guidelines for color schemes and markings. Vinyl used to produce fleet markings comes in large rolls that are fed through a plotter (cutter) or large-format printer/cutter. The designs are created in specialized computer software and sent to the machines via cable link for production. Once the design is cut into the vinyl, the excess vinyl on the sheet is removed in a process called "weeding". Finally, a paper pre-mask is applied to the top of the vinyl design to allow easy application of multiple letters and shapes at one time.
