Middle-aged drivers are most likely to have speeding fines according to an insurance survey, which also shows surgeons, company directors and barristers are heavy-footed behind the wheel.
A survey of more than 14m insurance quotes on Moneysupermarket.com showed that both men and women aged 40-49 had the highest conviction rate with 8.6 per cent and 11.4 per cent respectively. This was closely followed by those in their thirties, and then those aged between 50 and 64 years old.
Younger drivers are least likely to have a conviction for speeding, as male and female drivers aged 20-24 years old have a conviction rate of 7.2 per cent and 4.4 per cent respectively.
Barristers, company directors and surgeons are some of the professions most likely to be caught speeding, while cafe workers, building society clerks and students fall at the other end of the spectrum, and are unlikely to have penalty points for driving too fast.
The research also shows the cars that motorists are most likely to be speeding in - unsurprisingly, Porsche drivers top the list, followed by Aston Martin, Jaguar and Bentley. In contrast, lightly-footed drivers might own cars made by Daewoo, Fiat and Suzuki.
Moneysupermarket.com car insurance expert Kevin Pratt said: "The nation's drivers are living up to stereotype. Our data shows that professionals in high paid jobs driving fast powerful cars are more likely to be caught speeding than the average family car, or a car with a smaller engine. The temptation to speed is too much for some to resist."
