Your Eyesight:
You can’t drive on the roads unless your eyesight meets certain requirements.
The easiest way to check this yourself is to try to read a number plate at the specified distance and if you can't, you should visit an optician before you start.
The regulations state that, in good daylight you should be able to read a vehicle number plate with letters 79.4 mm (3.1 in.) high at a minimum distance of 20.5 metres ( about 67 feet)
If you need glasses or contact lenses to read the number plate that's fine. However you must wear them whenever you drive. If you have had sight correction surgery you should declare this when you apply for your provisional licence.
Applying for you licence:
You must be at least 17 years old before you can get a provisional car licence. However as a exception if you receive disability living allowance at the higher rate you can get your provisional licence when your 16.
Form needed (D1) from your local post office.
