Final answer:
The most important thing to remember about emergency braking is that if the wheels are skidding, you cannot control the vehicle.
Step-by-step explanation:
The most important thing to remember about emergency braking is that if the wheels are skidding, you cannot control the vehicle. When the wheels skid, the tires lose traction with the road, making it difficult to steer or stop the vehicle. It is crucial to maintain control by avoiding wheel lock-up and allowing the tires to maintain grip with the road surface.
