'STEALTH' speed cameras on the M25 in Surrey may have to be repainted yellow, a minister has said.
Roads minister John Hayes has called for the Highways Agency to urgently review the colour and signposting of the grey cameras, which were installed between junction 5 for Sevenoaks and junction 7 for the M23 last year as part of a multi-million pound upgrade to the carriageway.
The call comes amid concerns the 'secret' cameras are catching motorist unawares.
As well as clocking drivers breaking the 70mph limit, they also enforce variable speed limits which flash up on the gantries following an incident or to ease rush hour congestion.
Critics claim the cameras' inconspicuous appearance was causing motorists to brake heavily when they spotted them, making the road more dangerous.
Mr Hayes told the Telegraph he believed the cameras should be more visible.
He said: "I have been concerned about 'stealth cameras' and have ordered a review as a matter of priority to look at exactly where they are, what they are being used for and how they are signed.
"That includes the colour of them.
"It seems to me that it is important that they are identifiable. At the moment as you know people assume that speed cameras are painted yellow.
"I think it's really important that people know where speed cameras are. The suggestion that stealth is involved is not reasonable."
There are 46 camera spots on the entire M25, which can have up to six cameras each.
More than 600 drivers have been caught speeding on the M25 in two months.
