What are the GREY speed cameras on the M6?
What are the GREY speed cameras on the M6? The cameras, called the Hadecs3, will help enforce variable speed limits on motorways. But when the speed limit is at its normal 70mph they will not be switched off and can catch people going over the national speed limit.
Are M6 speed cameras always on?
The variable speed cameras are only switched on at certain times, keeping motorists guessing. More than 3,500 have been clocked breaking the temporary 40mph speed limit on the stretch of motorway during this year alone - 19 every day on average.
