When we think of "police vehicles," the first image that comes to mind is typically a marked patrol car. However, there are a variety of other vehicles that the police use to carry out their duties. Some synonyms for police vehicles include squad car, cruiser, patrol automobile, police van, police SUV, and paddy wagon. Some departments also have motorcycles, bicycles, and even boats that are specifically used for police work. In addition, many police departments also use unmarked cars for surveillance and undercover operations. Regardless of the type of vehicle, their purpose is clear: to help maintain public safety and enforce the law.
