To experimentally evaluate the effects of police vehicle types and esthetics on participants’ perceptions of police officers.
Using participant data (N = 307) from the Police Officer Perception Project (Simpson 2017), I experimentally assess the effects of police vehicles on perceptions of police officers. Specifically, I evaluate the impact of presenting officers in marked police vehicles (black and white versus white and blue), unmarked police vehicles, and unrelated (or civilian) police vehicles on perceptions of them as aggressive, approachable, friendly, respectful, and accountable.
Police officers are perceived differently when occupying different types and colors of police vehicles. For example, officers are generally perceived more favorably when occupying marked police vehicles than when occupying non-marked police vehicles. When occupying marked police vehicles, officers are generally perceived more favorably when such vehicles have a black and white color scheme than a white and blue color scheme.
Police vehicle types and esthetics impact perceptions of police officers in significant and meaningful ways. Like uniforms, police vehicles can be important symbols of legitimacy which exude presence and nonverbally communicate philosophies and intentions to the public. Police departments may tailor the perceived intentions of their motorized patrols by strategically manipulating the appearance of their vehicles.

Participants were led to believe that they would rate images associated with a randomly selected occupation and then recall such images during a later memory test, despite always observing police-related images.
All of the images feature real police officers in real police vehicles.
Verbatim instructions: “ATTENTION: Please rate the following images as either [dependent variable] or not [dependent variable]. When making your decisions, please move as quickly as you can observe the image in its entirety” (Simpson 2017).
