Motorists aged 50 and over have seen insurance premiums rise by more than a third in three years, new research suggests.
Older drivers are seeing insurance costs rise despite official data showing the number of incidents they're involved in has actually declined over the past decade.
Research by Consumer Intelligence found annual premiums for over 50s have risen by 34 per cent since 2013.
Meanwhile, 25 to 49-year-olds are being charged 24 per cent more for car insurance over the same period.
Experts suggest that the small increase of 2.9 per cent for 21 to 24-year-olds is because of a rise in the use of 'telematics' boxes that track driver movements, helping to bring down costs and reduce accidents.
Ian Hughes, chief executive of Consumer Intelligence, said the increased cost of premiums has come because the population of older people is growing faster than any other age group, leading to a tipping point of 'greater liability'.
However, official figures from the Department of Transport show that the number of over 50s killed or seriously injured in road traffic accidents has declined over the past 10 years, while the number sustaining smaller injuries has remained stable.
"Every time an older driver does something daft, there are calls for bans and retests and so on. But in fact many older drivers know their limits and they are actually more careful on the roads than younger drivers," he said.
Some of the price hikes can be attributed to the rise in insurance premium tax in 2015, which increased from six per cent to 9.5 per cent, adding about £20 to the average cost of insurance.
