FAQ: Is the emergency stop one of the driving test manoeuvres ??
No, it is an exercise that is completed out in approximately a third of category b ‘L’ practical driving tests. So it could appear in your test in addition to one of the specified reversing manoeuvres (Turn in the road, reverse round a corner, parallel parking and bay parking).
At the start of your test, the examiner will inform you that the exercise may be carried out. If there is time and opportunity, when stationary you will be briefed that the exercise will take place, sometime soon after the next time you move off again.
