In
the early parts of the 20th century police used to be seen walking the
beat. Now, however, in order to maintain visibility in suburban communities
and urban areas as well as on highways police use police cars for transportation.
A police car needs specialized equipment to allow officers to do their
job on the road.
Police car equipment has come a long way since the first car was introduced
in America on the streets of Akron, Ohio in the late 1800s. The first
car could only travel 30 miles because of its weak battery. The vehicle
featured electric lights and used gongs to make noise. It also had a
stretcher which was used to pick up drunks.
Today's police cars are typically passenger cars offered by vehicle
manufacturers such as Ford and GM which come with OEM police packages.
Police can also modify these vehicles by adding their own equipment
after making a purchase. Depending upon the need of the department the
car can be made more durable and faster. Police departments can alter
the engine, suspension, and brakes to have the car fit their needs.
In addition, the electrical system of the car is usually upgraded because
the vehicle must accommodate additional electrical demands for radios
and lights.
Most police cars have warning systems that alert other cars to their
approach on the road. Police in the United States are supposed to only
use these audible and visual warning signals in case of emergency. However,
some drivers have accused police of sounding their siren simply to move
faster in order to pass cars and avoid the rules of intersections. (Police
are exempt from speed limits and other laws when visual or audio warnings
are in operation on the car.)
There are two kinds of visual warnings: passive and active. Passive
warnings are simply the colors on the car. Bright colors or stripes
signal to other drivers than a police car is near. Increasingly, highway
state police use my marked cars while they are on duty to catch a greater
number of speeding drivers.
Active visual warnings must be turned on by an officer. In the early
1950s police cars had lights that were stationary and flashed red in
the front and amber in the rear. Today's police cars use different colored
lights which are flashed in order to alert the driver of the officer's
presence. Common colors for today's police sirens are blue and red.
Police cruisers are also equipped with rotating beacons, halogen lights,
or strobe lights. In addition, headlights of some vehicles can be altered
so that they flash.
Police also use audio warnings so that other drivers are aware of the
police's presence. Audio warnings are usually called sirens. Police
are also able to amplify their voice to give orders to citizens with
bull horns.
Other important pieces of police car equipment include:
• Two-way radios
• Enclosures to transport suspects
• Equipment consoles
• Radar guns
Smaller items like radios and radar guns can now be ordered à
la carte and in bulk over the Internet to save money.
