The Driver and Vehicle Licensing Agency (DVLA) has warned that people over 70 must renew their licence every three years.
If they do not do this, it means that they will no longer, legally, be able to get behind the wheel. And they may even face a fine.
The reminder comes as the government agency took to Twitter and wrote: "After you turn 70, you need to renew your licence every three years. It’s easy, quick and secure to do it online."
