I was checked for the first time with a laser gun. Naughty enough also very close to a police station My speed was in the tolerance range (according to the speedometer 40 km/h in a speed 30 zone – there will probably be nothing). But how is it basically with the proof power? No photo is taken. Every driver / holder could talk out according to the motto “I did not drive”, unless it is stopped immediately afterwards. Furthermore, the measurement is in the hindsight of the in order to check whether the beam was directed directly at the plate plate (as it should be) or whether the reflected laser beam was ultimately from a car driving behind/next to it. This also resulted in a test in the current ADAC engine world.
