When the examiner commands an 'emergency stop' during the practical test, what is the correct candidate response?

1. Pull the handbrake hard while it is still at speed, keeping a light hand on the wheel
2. Brake firmly and progressively at once, both hands on the wheel, dipping the clutch just before the halt
3. Check every mirror first, then ease off the accelerator and brake once the road behind is clear
4. Steer for the kerb or the verge as you brake, so the car leaves the running lane as it stops
