SPEED camera chiefs have been accused of being 'sneaky' for planning to set up mobile traps -- just yards after drivers have passed fixed sites.

Police and council bosses believe that drivers are getting wise to the location of speed cameras across Lancashire, slowing down as they go past and then speeding up again.

Now they plan to catch drivers beating the cameras by using mobile cameras within a 500 yard radius at 74 well-known traps.

Ian Bell, a former police chief inspector who now heads up the Lancashire Partnership for Road Safety, said: "People are slowing down for the cameras and that is good news, but there are people who simply speed back up again, which is why we will be using mobile cameras further down roads to catch people.

"There is no doubt that speeding is dangerous and it costs lives. The cameras are there to make the roads safer."

Motoring organisations today claimed it was proof that cameras did not make roads safer and the speeding problem was just being shifted to new locations.

Kevin Delaney, traffic manager at the RAC, said: "There is something sneaky here. If cameras aren't working in locations, they shouldn't be there and alternative ways of controlling the speeds of drivers should be looked at."

A spokesman for the Association of British Drivers said today: "They can't place cameras everywhere and this is a sneaky way of making money."
