Age limit for grant of a driving a licence

I want to buy a car for my father who is 85 years old as a Christmas gift. Does the law allow such an old man to learn driving and get a driving licence? Is there an age limit for getting or holding a driving licence?

Section 25 of the Road Traffic Act [Cap.168 R.E 2002] provides only the minimum age for grant of a driving licence. Extreme old age does not, in itself, disqualify a person from getting a driving licence unless he is suffering from vision problems attributed to old age. The minimum age for driving a car is 18 years. A person under the age of 16 years is totally disallowed to get a driving licence but a person between the age of 16 and 17 can get a driving licence but only for moped motorcycles. Unless there are other reasons we are not aware of, you can proceed to buy the car for your father. Remember that even if he cannot drive, you can always employ a driver so the old man can enjoy his car!
