A new survey has found that only half of the fixed speed cameras on our roads are actually switched on.
Northamptonshire has been highlighted as one of four police forces across the country where none of their cameras are in use.
The force says it switched its 39 cameras off in 2011 but have left them in place to deter speeders.
The only county in our region to still have all of their fixed speed cameras active is Suffolk.
In Norfolk, 17 of the county's 24 cameras are switched off, while in Essex, which only provided rough figures, 33% of cameras are in use.
