More than a third of drivers do not know what the speed limit is on roads, a new study has revealed.
OnePoll questioned 2,000 people on behalf of Co-operative Insurance, with 36 per cent of them unaware that the national limit on a dual carriageway was 70mph.
More than a quarter (27 per cent) believed it was 60mph, while two per cent thought it was 80mph or higher.
Motorists in London had the least awareness of speed limits, but, so often thought of as being more dangerous – younger drivers had the greatest knowledge of the limits.
Steve Kerrigan of the Co-operative Insurance, said: “These figures show that all too often drivers are getting into their cars and driving with no real awareness of the speed limits in place.
“It is interesting that younger drivers - who are so often thought as being more dangerous - are so much more aware of national speed limits than older, often more experienced drivers.”
