What's the minimum distance from which an approved driving instructor (ADI) must be able to read a number plate?
- A 20.5 metres
- B 27 metres
- C 30.5 metres
- D 36 metres
Why this is the answer
Trainee driving instructors will have their eyesight tested at the start of their Part 2 examination. A number plate, where the letters and figures are 79 mm tall and 50 mm wide, must be read at a minimum distance of 27 metres. If a trainee driving instructor cannot pass this test, their Part 2 examination will go no further. This will not, however, affect their licence to drive, as the ADI eyesight test standard exceeds the legal eyesight requirement.
Why the other answers don't fit
- A
- 20.5 metres — 20.5 metres is the standard for an ordinary driving test, not for an instructor.
- C
- 30.5 metres — 30.5 metres is further than the instructor standard requires.
- D
- 36 metres — 36 metres is further still.
Where this comes from

Where this question comes from
The question, its options and the explanation are reproduced word for word from the DVSA revision question bank under licence. The licence requires them to appear unaltered, so we cannot reword them and neither can anyone else — that is why you will meet the same wording on other sites. Everything else on this page is written by Theory Hub: the explanation of why each wrong answer is wrong, the topic guide and the revision notes.
