Drivers aged 70 and over have been warned that they must renew their licence every three years.
The reminder from the Driver and Vehicle Licensing Agency (DVLA) comes as recent figures show there are now about 10million drivers aged 70 and above in the UK.
Motorists who do not renew their licence once they have passed their 70th birthday will no longer be able to legally operate a vehicle, and will be committing a serious offence if they carry on driving.
