More than 30,000 UK motorists were caught driving at 30mph or faster on roads with a 20mph limit last year, an investigation has found.
The figures obtained by the RAC also include cases of extreme speeding, with a driver clocked at 89mph on a 20mph stretch of the B5129 in Deeside, North Wales, and another caught doing 114mph on a 30mph road near a primary school in Aylestone, Leicestershire.
