The evidence really doesn’t support older drivers being more dangerous. From the BBC website:
But how dangerous are older drivers?
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. Its 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.
"There's a stat that young drivers under the age of 24 have twice as many crashes as you'd expect, given the numbers on the road, and older drivers have half as many as you'd expect, given the number on the road," says Neil Greig, director of policy and research at the Institute of Advanced Motorists (IAM).
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.
