In Kent only a small percentage have cameras in, they are set up when the area has experienced a number of accidents over a period of time. Once the number of accidents drops below a particular number they then have to remove the camera as it is no longer a hot spot. What they do is leave the box set up with Flash etc and all it does is scare people from then onwards.

Digital cameras cannot be moved around anywhere as easily as a film camera and cost a lot more money therefore they are generally only set up in areas where it would be dangerous to get to to change a film.

Gatso's only get people driving away from them and as a result getting flashed towards them is not a problem. The white lines are what actually catch you as the machine cannot be relied upon to prove your speed - it is only just used as a method to alert the authorities. It takes your photo and then the person who reviews it confirms your actual speed by the position of your car on the white lines. You have to be confirmed speeding by an individual not a machine.

Some people have gone to court and won when it comes to handhelds from bridges long distance away. They can zap you coming head on a mile away and have all of the details suggesting you were speeding. however people are now going to court saying it is near impossible for a policeman a mile away to confirm 100% without their camera/recoding device that you are speeding when driving head on to him at that distance - these are now getting thrown out.

In kent also they only are authorised to use mobile outfits within 1km of the hot spot. Quite interesting! Not sure if this is govt regulation or just a choice of the kent coppers

Truvelo's I do not understand though. How does a human intervene and confirm the car was actually speeding? It is hard when there is only one white line with differing lengths of cars unless it only zaps your car at a particular height? I'm confused about that one.

hmm.. ok got it. though I didnt realise there were two inductive strips - always thought there was just one

 

I got clobbered by the Gendarmerie on an autoroute in France last year who were using a hand held radar gun quite some distance in front of me. The patrol car pulled me over and escorted me to the next exit where there was a cop shop (gendarmerie boulangerie?) alongside the toll booth. They showed me a chart which indicated two speeds - the one they recorded and the 'discounted' speed on which they calculated the on-the-spot fine. 165 km/hr they recorded = 140 km/hr 'discounted'. That seems to be the way they overcome any accusation of inaccuracy. Cost me
