Detection range can be as low as 100 feet or lessto over a mile. A radar may track a distant large vehicleinstead of a closer small vehicle without any indication to theoperator which vehicle the radar is tracking..
In this regard, how far can police radars reach?
Generally speed measurements are taken when you arewithin a 1000 feet and sometimes closer when an officer hides in astationery position. Fortunately all radar detectorsproduced today can detector radar from distances that aregenerally much greater than that.
Also Know, how far away do police speed guns work? The speed reading takes no less than 3 secondsfor the police officer to acquire. The range of thesesystems is about 300 yards.
Moreover, how far does a speed camera reach?
Typically, depending on the type of mobile speedcamera, the range will be about two miles on a straight bit ofroad – they cannot work round bends or over brows ofhills.
At what distance are radar guns accurate?
Laser guns can be very accurate—somemodels boast an accuracy of within one mile per hour up to60 miles per hour, and an accuracy of within three percentfor speeds over 60 miles per hour. That being said, laserguns are not infallible. Excessive cloud cover, rain, windor fog can negatively impact a laser's reading.

Can cops tell if you have a radar detector?
For the most part, a Radar detector is a passivesystem. It does not emit a signal to be detected. So a policeradar is not going to detect the radar detector. Still,a Cop can tell if you have one anyways.Can police radar clock two cars at once?
A. Troopers use a handheld laser gun that enables theclocking of cars in rapid succession. So while they cannotclock two cars at the same time, they can clock oneand then quickly clock the other, said Troy Pope, firstsergeant of the N.C. The laser signal expands only a few feet,while radar can expand wider.Can police detect laser jammers?
Additionally, many police radar guns are equippedwith devices that are capable of detecting a jammersignal. Laser jammers, however, are fairly effective. Whenused in conjunction with a high-tech radar/LIDAR detector,some laser jammers can effectively render a laserspeed gun momentarily inoperable.Does a police officer have to show you proof of you speeding?
Generally, speeding motorists are not entitledlegally to check the radar when pulled over.
