REASONS FOR FAILING THE EMERGENCY STOP

Reasons for failing.

* Not reacting quickly enough. Not getting to the brake pedal quickly enough so the vehicle travels further than it should.
* Not stopping quickly enough. Not pressing the pedal firmly enough resulting in the vehicle traveling further than it should.
* Vehicle skids out of control. Stamping on the pedal resulting in a skid, although a small skid if bought under control quickly might not fail you.
* Hand taken off steering wheel before the vehicle stops. Hand goes for the parking brake or gear stick before your vehicle has stopped.
* Applying the parking brake before the vehicle has stopped. This could result in the vehicle going out of control.
* Not checking your mirrors once you have stopped. You will not be aware of what is going on behind you.
* Not completing an all round observation once you are asked to drive on. This must be done as always before you drive on, having stopped at the kerb, before moving off from a controlled stop or other manoeuvres, exception would be stopping in traffic queues unless you felt it was necessary.
* Not signaling if there were someone to benefit while stationary or before moving off after the Controlled Stop. It could be a car in front or behind you, let them know you are stationary or let them know you are about to move off, if it is safe to do so.
