Plans for ‘secret’ speed cameras to catch drivers exceeding 70mph are set to hit South Yorkshire’s motorways.
The Highways Agency has earmarked stretches of the M1 for the introduction of new cameras, which are likely to be grey in colour rather than the traditional bright yellow.
And there will be no white road markings to provide prior warning to motorists.
Cameras are currently being tested by the Home Office and some could be put in place between junctions 28 and 31 and from 32 to 35a as early as this year.
It is the first time cameras will be installed along busy routes in such a way. Equipment has previously been limited to stretches undergoing roadworks.
Richard Wright, executive director of Sheffield Chamber of Commerce, has campaigned for improvements to the M1 and fought against a planned speed restriction affecting junction 35a at Sheffield and Rotherham.
He said: “As a chamber we are focused on fighting the 50mph limit and improvements to junction 35 across three lanes over Tinsley viaduct.
“We would rather the cameras were there and the limit stayed 70mph. I can in no way advocate exceeding the limit or breaking the law.”
The cameras are part of a new ‘digital enforcement camera system’, which will be up and running on 100 miles of motorway in the next two years.
A spokesman for the Highways Agency said: “These are not stealth cameras - they are more visible than they were before.
“These are not about speed limits. They are about smoothing the traffic flows and increasing capacity.
“The onus is on the driver to abide by the speed limit.”
