Police vehicles or
commonly known ad radio car are used for detaining, patrolling and
transporting. The common Police patrol vehicle is an improved four door
sedan (saloon in British English). Police vehicles are usually marked
with appropriate logos and are equipped with sirens and lightbars to aid
in making others aware of police presence.
Unmarked vehicles are
used primarily for sting operations or apprehending criminals without
alerting them to their presence. Some cities and counties have started
using unmarked cars, or cars with minimal markings for traffic law
enforcement, since drivers slow down at the sight of marked police
vehicles and unmarked vehicles make it easier for officers to catch
speeders and traffic violators.
