Almost four in five motorists admit driving over the speed limit, according to a survey.
As many as 16% of male drivers and 6% of women motorists said they frequently exceeded limits, the poll by insurance company Admiral found.
A total of 26% agreed it was acceptable to go over the speed limit, with this figure rising to 36% for male drivers. Drivers aged 18-24 were the ones most likely to think speeding was acceptable but they were not the ones most likely to exceed limits, the survey of 3,614 motorists showed.
Those aged 30-34 and 35-39 were most likely to speed, with 81% of drivers in these age ranges admitting going over the limit. In contrast, the figure for 18-24 year olds admitting speeding was 72% - the same as for those aged 70 and over.
In total, 55% of drivers thought the motorway speed limit should be raised from the current 70mph to 80mph, while 14% wanted the limit higher than 80mph. The majority of drivers (56%) wanted the limit on residential streets to be 30mph, with 40% supporting 20mph limits and only 3% wanting the limit to be 40mph.
On average, those polled drove 140.5 miles a week, with the vast majority (80%) reckoning their mileage will stay about the same over the next 12 months.
As many as 31% believed they would not pass their driving test if they had to re-sit it, while 45% admitted ignoring advice and driving in bad weather on at least once occasion.
On the drink-drive legal limit, 48% said it should be lowered, with 39% supporting no change and 7% backing a higher limit.
Admiral managing director Dave Halliday said: "Our statistics show a worrying trend where people view a speed limit as simply a guide rather than a speed that's appropriate for that road. It's also a concern to see the different attitude between the genders, particularly the huge number of men who admit to driving over the speed limit and those who believe it's acceptable."
He went on: "It also appears that young motorists could do with some re-education, as so many thinking that speeding is acceptable is not a good sign."
