Short Range
This highlights the difficulties of short range detection.The beam is very
narrow and with a single sensor it is not possible to cover both
scenarios.
Long Range
At long range it is not possible to choose which part of the vehicle they
want to target. On some Laser Guns the sight is bigger than the vehicle.
Wherever the detector is fitted is it possible to trigger it.
Following a vehicle being targeted
At short range it is difficult to detect, but if the vehicle in front is
targeted from long to medium range it is possible to detect as long as
the sensor is fitted to the front windscreen.
Rear Detection
When the vehicle is targeted from the rear, the laser signal will pass
thorough the rear windscreen and trigger LASER ALERT as long
as no obstructions are in the way.
Laser Detection
How the enforcement officer chooses which vehicles to target
Even though the police have equipment for measuring and recording the
speeds of motorists, it is down to the officer using the equipment to
choose which vehicle to target.
A lot of people believe that the police are checking every vehicle as they
go by.This is not the case. Guidelines state that an officer can only
measure the speed of a vehicle that they believe to be exceeding the
posted limit.This is often why a driver with a Laser detector fitted may
see a gun or van nearby, but will not get a warning alarm as they
drive by.The majority of the time they are targeting the number plate of
the vehicle as this is normally vertical to the road, but any part of the
vehicle could be used.
