The majority of fixed speed cameras in the UK are only activated by motorists going 10% plus 2mph above the speed limit, an investigation has confirmed.
Freedom of Information requests to 33 police forces in England, Scotland, Wales and Northern Ireland – carried out by AutoExpress – reveal 22 forces adhere to the 10% plus 2mph prosecution guidelines set by the National Police Chiefs’ Council.
However, eight forces were unwilling to reveal the threshold they use over concerns it could encourage motorists to speed.
Two forces – the Metropolitan Police and Lancashire Police – are more lenient, adopting a 10% plus 3mph threshold.
The Met says this is ‘a proportional response to the high volumes of traffic’ in the Capital, while Lancashire Police says it operates this threshold ‘to ensure greater tolerance or discretion’.
Speaking to AutoExpress, Edmund King, AA president, said it is sensible to have some flexibility with speed-limit enforcement, “as the last thing we need is drivers concentrating solely on the speedo and not the road”.
All police forces confirmed their thresholds apply to both fixed and average speed cameras.
