What is the correct procedure if a tire blows out while you are driving at high speed?

1. Slam on the brakes as hard as possible and turn the steering wheel quickly toward the road shoulder so you get off the carriageway at once.
2. Hold the steering wheel firmly, ease off the accelerator, let the vehicle slow down naturally, and steer gently to a safe stop.
3. Accelerate to stabilize the vehicle, then pull the handbrake.
4. Shift to neutral immediately and turn off the ignition.
