The number of drivers over the age of 80 has now topped one million, according to information obtained by the IAM, following a freedom of information request to the DVLA.

The DVLA figures show that there are now 1,012,399 drivers over 80. There are also 122 licence holders over the age of 100, including three 105 year olds, and one 106 year old woman.

The age gap between the youngest driving license holder and the oldest is 90 years.

But contrary to common assumptions, says the IAM, drivers in their eighties are not dangerous. The figures show that they are in fact much safer than their more youthful counterparts.

The rate of deaths and serious injuries in crashes among drivers over 80 is three times less than the rate for those aged 17 - 19. In 2010 almost one young driver aged 17 - 19 was killed or seriously injured per thousand licence holders, while the rate of deaths and serious injuries in crashes among car drivers aged 20 to 24 is 36.4% more than the rate for drivers aged 80 or over.

However, drivers over the age of 80 are more likely to suffer serious injuries in a car crash due to their frailty.

“Older people need their cars which give them better mobility and access to more activities and services," said IAM chief executive Simon Best. "Those who wish to continue driving beyond the age of 70 should only be prevented from doing so if there are compelling reasons. Rather than seeking to prevent older people from driving, we should make them more aware of the risks they face, and offer them driving assessments to help them eliminate bad habits. Driving helps older people play a full and active part in society.”
