Pursuit Equipment
The primary piece of equipment that a police force officer rely in a pursuit is the police car . Modern police cars are special " police interceptor " adaptation of large sedan made specifically for constabulary work by car manufacturers . The most common constabulary car in production today is the Ford Crown Victoria , although police officers also use Chevrolet Impalas , Chevy Tahoe SUVs , Dodge Intrepids , and Jeep Cherokees . The Italian constabulary even use a Lamborghini .
There are quite a few differences between a constabulary car and the civilian version of the same car . law departments often opt for higher H.P. engine , not only because police car consider more , but for the quickening and speeding needed to catch up to criminals in a high-pitched - swiftness interest . law railroad car obtain harsh intervention on a day-after-day basis , idling for a farseeing time and then roaring off at gamey speed . To get by with the extra high temperature , transmissioncoolers and rock oil coolers affix heavy - dutyradiators . Alternators in constabulary cars can crank up out up to 130 AMP to lead lights , sirens , radios and other equipment [ ref ] . There are other differences touch to suspect conveyance , such as metal reinforce rear end backs ( to prevent stabbings from behind ) and vinyl cover terrace rear seats for easy cleansing .
Flashing lights and loud sirens zippy civilians that a police car is coming at high hurrying . The lights evolved from rear lamp in the thirties , and were earlier mounted on fenders . By the mid-70s , cap - mount up lights of varying colors were placed within an aerodynamic enclosed illumination saloon [ ref ] .
There are several system that law can deploy ahead of a Salmon P. Chase to deactivate the fleeing vehicle . The most common are spike that puncture and deflate the tires . These are generally rise on a bar or flexile cablegram , and deployed across the route . Models usable let in the Magnum Spike , Stop Sticks and the Stinger .
A method acting often view in moving-picture show that police really use is the law barrier . By park several elevator car across the road , or using some other form of barrier , police force can slow or stop a malefactor involved in a following . Even if the suspect avoid the roadblock , it usually diverts their course or forces them off road , where they ca n’t tug as fast and their railway car might be damaged .
More elaborated ( and often experimental ) system seek to incapacitate the car ’s electrical system . TheHigh Speed Avoidance Using Laser Technology ( HALT)system would allow officers to cut the fuel provision to the railway locomotive by simply firing a laser at the car , gradually slow it . Only vehicles fit with a special micro chip could be disabled , however [ ref].Another companyis uprise a microwave oven torpedo that would overload the electric systems and computers in a gondola .
If officers have air support , they do n’t even need to remain within sight of a take flight defendant . Police helicopters can maintain visual contact at greater speeds and without having to concern about terrain or route experimental condition . When equipped with infrared or dark vision camera , they can even carry on a pursuance at night or through big undergrowth .
