How dangerous are elderly drivers?

The number of over-70s holding a UK driving licence has exceeded four million for the first time. But how dangerous are older drivers?

There are occasional very well-publicised stories about elderly drivers going the wrong way on a motorway or dual carriageway. Only last week an 84-year-old woman died after driving the wrong way on the A1 in Northumberland.

The RAC Foundation says the UK's oldest licensed driver is a 107-year-old woman, and there are 191 people over the age of 100 with a licence. They are among 4,018,900 people aged over 70 with full UK driving licences.

The Department for Transport (DfT) says there is no evidence older drivers are more likely to cause an accident, and it has no plans to restrict licensing or mandate extra training on the basis of age.

There were 10,974 accidents involving drivers over the age of 70 in 2011, says the DfT. That compares with 11,946 accidents involving 17-to-19-year-old drivers and 24,007 accidents involving 20-to-24-year-old drivers. These statistics do not account for who caused the accident.

Figures also show that 46 drivers aged 16 to 19 died in an accident, while 173 drivers aged between 20 and 29 involved in an accident died. That compared with 59 deaths in drivers aged between 70 and 79 involved in an accident, and 52 over the age of 80.

The young-versus-old driver data is used by a number of road safety charities to argue elderly drivers don't pose the greatest danger behind the wheel.

Research by the RAC Foundation suggests drivers aged 75 and over make up 6% of all licence holders but account for just 4.3% of all deaths and serious injuries. By contrast, drivers aged 16-20 make up just 2.5% of all drivers but 13% of those killed and seriously injured.

"There are huge benefits to people driving, it helps them feel empowered. What we want people to do is see their optician regularly, and go to independent assessment centres if they are concerned," she says.

"There's some evidence that suddenly stopping driving and a lack of mobility leads to depression, so we want to keep people independent for as long as possible. The key thing is for people to start preparing for it early so they have other options,"
