In the UK, the minimum age for driving on public roads is 17 and you must have a provisional driving license. You can apply for your provisional driving license 3 months before your 17th birthday (it will come into effect on your 16th birthday).
The only exception to this is if you are receiving disability living (mobility) allowance at the higher rate. In this case you can apply for your provisional driving license 3 months before your 16th birthday (it will come into effect on your 16th birthday).
To apply for your provisional driving license see below.
