Insurance broker the Allen and Allen Group showed that 25 to 30-year-olds were high risk, with teenagers falling more than 20 places lower on the risk scale.
Tony Allen, chief executive of the Allen and Allen group, said: 'The figures turn public perception on its head and while not based on the whole industry, the statistics are still enough of a representative sample to make insurers stop and reconsider their approach to this group.
'The numbers in this survey alone suggest there are a lot of people out there who may be teetering on the brink of losing their licences or facing large rises in their insurance premiums in the near future.
'Perhaps it is time the industry thought less about the age of drivers and more about the consequences of this repressive policy of penalised motorists.'
Motorists in their 20s accounted for 861 of the total 2,336 speeding convictions recorded.
Drivers in their 30s accounted for 707 convictions with 60 and 70 year olds only accounting for 34 convictions.
