The latest stealth speed cameras have now been switched on – although they had been idle since their installation in 2009.
Cameras had previously been active only between junctions two and three, but have now been switched on along the entire Surrey stretch.
A Surrey Police spokesman told the Surrey Comet: ‘The speed cameras on the M25 are active and the speed limit is enforceable.’
The move hasn’t gone down well with everyone. Claire Armstrong, co-founder of Safe Speed, told the newspaper: ‘Motorways are our safest roads. To put speed cameras on our safest roads is nothing short of ludicrous, dangerous behaviour.’
The cameras are grey and are placed on gantries. They are capable of monitoring four lanes of traffic at the same time, and do not flash when they capture a speeding vehicle. There have been complaints because motorists driving only fractionally above 70mph have been penalised, while recommendations by chief police officers are that prosecutions should be brought only when a vehicle is travelling at ten per cent plus 2mph over the limit – that’s 79mph on a motorway.
