100 Year Old DriverASSOCIATED PRESS

Approaching the subject of an elderly relative's continued ability to drive safely can be tricky. How do you suggest that your parent or grandparent should give up their car due to their age, without sounding patronising or downright offensive?

With an increasing number of older drivers on the roads, the issue is becoming a growing problem for families concerned for the safety of their elder loved ones. If you're looking for a way of bringing up this thorny subject, you may want to consider the Mature Driver's Assessment from the Institute of Advanced Motorists (IAM).

Aimed at giving older drivers a trusted second opinion on their driving, the assessment is open to anyone over 70 and consists of a 60 minute drive with an IAM-approved assessor in the passenger seat.

It's not a formal test, but participants will receive immediate feedback at the end of the session as well as a confidential written report on their driving ability. Those judged to have above average or competent skills behind the wheel will also receive a certificate, while those who need improvement will be offered advice and guidance on how to improve.

IAM chief executive Simon Best said: "This assessment helps keep older people driving for as long as it is safe to do so. It's worth remembering that many older people actually give up too early, simply because they lack confidence. It also gives elderly drivers and their families the information they need so that they can choose the right time to give up driving."

The assessment costs £35 and can be booked at the IAM website.
