If you wish to keep your driving licence after you have turned 80, you need to submit a health certificate from your doctor.

How to renew your driving licence with a health certificate

Remember that you must not drive a vehicle while temporarily ill, suffering from poor health or when the use of medication renders you incapable of driving safely. If you are uncertain whether you meet the health requirements, ask your doctor if you need a health certificate even if you have not reached the age of 80.

Your doctor is obligated to report to the county governor if you over an extended period of time (6 months or more) fail to satisfy the health requirements for a driving licence.
