An RAC investigation finds that more than 30,000 motorists are caught driving at 30mph or faster on 20mph roads in the UK each year. The report focuses on drivers who exceed the posted 20mph limit by a significant margin, indicating that a subset of road users travel far above the speed intended for those streets. According to the investigation, the total figure for last year reaches over 30,000 such incidents. The coverage notes that some vehicles reach “chilling” levels, emphasizing the scale of the problem among the most severe speeders. The sources describe the finding as based on enforcement data used by the RAC to identify the worst speeding cases on 20mph routes. The reports do not detail the geographic distribution, enforcement methods, or the specific circumstances behind each recorded instance, but they present the headline figure as a key indicator of how often drivers substantially breach 20mph limits.
