Walter Arnold of East Peckham, Kent had the dubious honour of being the first person in Great Britain to be successfully charged with speeding on 28 January 1896. Travelling at approximately 8mph/12.87kph, he had exceeded the 2mph/3.22kph speed limit for towns. Fined one shilling and costs, Arnold had been caught by a policeman who had given chase on a bicycle (National Motor Museum).
