Final answer:
When making a quick emergency stop, use forceful and quick braking while maintaining control of the vehicle.
Step-by-step explanation:
When making a quick emergency stop, you should brake as quickly and firmly as possible, while maintaining control of the vehicle. A sudden and forceful application of the brakes will help to slow down the car and bring it to a stop as quickly as possible. It is important to keep both hands firmly on the steering wheel and not to slam on the brakes, as this could cause the car to skid or lose control.
