To become an ADI you must successfully complete a three part qualifying examination. Part 2 is a practical test of your driving ability.

About The Test

The practical test of driving ability consists of tests of both eyesight and driving technique. The test lasts for about 1 hour. You must pass both parts of the test at the same time.

The test of eyesight

You must be able to read a be able to read in good daylight with the aid of glasses or contact lenses if worn, a motor vehicle registration mark containing letters and figures:-

  • 79 millimetres in height and 50 millimetres wide at a distance of 26.5 metres; or
  • 79 millimetres in height and 57 millimetres wide at a distance of 27.5 metres.
  • If you do not pass the eyesight test, you will not be allowed to take the driving ability test.

The test of driving ability

This test is not just a slightly more difficult ‘L’ test. It is of an advanced nature and a very high standard of competence is required. You must show that you have a thorough knowledge of the principles of good driving and road safety and that you can apply them in practice. In particular you must satisfy the Examiner on all or any of the following subjects:

  • expert handling of the controls;
  • use of correct road procedure;
  • anticipation of the actions of other road users and the taking of appropriate action;
  • sound judgment of distance, speed and timing; and
  • consideration for the convenience and safety of other road users.

The routes used for the test will include roads which may carry heavy traffic or fast moving traffic, for example motorways or fast dual carriageways. The routes will be both inside and outside built-up areas.

You will also have to demonstrate your ability to perform on 5 occasions a check on the condition and safety of one component of the vehicle. Checks will be chosen from a list of the components, e.g. tyres, steering, etc. Failure to answer questions correctly will accrue driving faults.

Occasionally the Examiner’s Supervisor may wish to come along as well. Don’t worry, they will not be concerned with your performance but with the examiner’s and will take no part in the conduct of the test.
