ADI PST 5 - Emergency Stop and Use Of Mirrors

This is split into 2 parts - The use of mirrors as you drive to the place that you will do the emergency stop... and the Emergency Stop itself.

Setting the Scene

Use of Mirrors: Emergency Stop

(See our video tutorial notes to this PST on our You Tube page. Here)

This exercise will be introduced to the PDI by the examiner saying:

“I would like you to give me some practical instruction on the use of the rear view mirrors and also to instruct me in how to make an emergency stop - that part should include a briefing followed by practice.

Assume that I…….” (It should be made clear that there are two elements to the test and that both should be covered and that the examiner will select a suitable location for the ES. Suggest that the brief for the ES be given when you arrive at the chosen location).

Examiners will appreciate that it is usually preferable to deal with this exercise in the order outlined above. If necessary, PDI’s should be encouraged to do this.

Use of the Mirrors:

The PDI should deal with the mirrors from a general aspect of the driver’s seating position and mirror adjustment, and the importance of rear vision at all times this involves regular use of all mirrors during general driving.

In addition, they should refer to the possibility of “blind spots”; examiners need to be wary as to not to force a change in lesson plan by simulating move off faults. Mirror faults should be of a general nature and not so that a lesson on a different subject may be suggested.


Not checking mirrors as and when required

Emergency Stop:

The PDI should explain what happens in any emergency stop and how it is brought about; points to be covered are the importance of quick reaction; appropriate use of the foot-brake and clutch; avoiding locking the wheels, and correction of skids.

They should also be expected to make some reference to the dangers involved in stopping in an emergency and to the need to avoid such stops so far as possible.
