Question: how do you renew your driving licence when you reach 70?
Answer: The DVLA will send you a D46P application form 90 days before your 70th birthday, and then every three years afterwards. Complete the form and return it to the DVLA. If you haven't got the D46P form, you can use a 'D1 application for a driving licence form', which you can pick up from a Post Office.
