If you thought it was tough learning to drive at 17 then it could be argued it is five times tougher for someone aged 91.

That is the age of the oldest driver to have taken their test in Sussex last year but the pensionable learner is not alone.

More than 500 drivers aged over 50 attempted their driving test in Sussex last year including 13 aged over 71.

Two 88-year-olds also attempted their driving tests.

Because of Data Protection Rules, the Driving Standards Agency (DSA) said they couldn’t give any further details about the elderly drivers, where they took their test or even if they passed.

Almost exactly the same amount of 50-plus drivers took their test in 2009 which was fewer than the 540 who took their test in 2008.

The number of drivers over 71 taking their tests has remained constant in the last three years although they are becoming increasingly less successful with a pass rate of less than 10% in 2010 compared to a pass rate of more than 25% in 2008.

And while these drivers may have experience on their sides, they aren’t as successful as the general public as a whole.

The pass rate of 50-plus drivers last year was 35% compared with 47% for all ages.

Matt Harman, of Hassocks-based Harman Driving School, said: “I guess for some of these drivers the motivation to learn probably comes from the fact that they always had someone to drive them around.

“Now something might have happened to that other person, they might suddenly realise they can’t get from A to B especially if they live in a rural area.

“I think the hardest thing for these drivers is that they don’t have as quick natural reaction as younger drivers.”

Some people have advocated a compulsory test for drivers aged 70 and over to prove they are still competent behind the wheel.

At present, a driving licence expires when a driver is 70 and they then have to renew their licence with the DVLA.

Drivers are asked to disclose any conditions that might affect their driving ability when they reapply.

A DSA spokesman said: “It’s possible somebody aged 91 wouldn’t have taken their test in the first place.

“They were only introduced in the 1930s and before that somebody would apply for a licence.”
