Emergency braking refers to the act of rapidly reducing the speed of a vehicle in response to an unexpected hazard that may pose a danger to the driver, passengers, or others on the roadway. It involves applying the brakes forcefully to bring the vehicle to a stop as quickly and safely as possible, which is a critical response in crisis situations.

In this context, the choice indicating that emergency braking means responding to a hazard by slowing the vehicle accurately captures the essence of the action taken by a driver. This technique is fundamental for avoiding collisions or mitigating the effects of an impending impact when a significant risk is identified on the road.

The other options do not pertain to the concept of emergency braking. For example, slowing down when approaching a stop sign is part of regular driving behavior rather than a reaction to an emergency situation. Similarly, responding to a hazard by accelerating would be reckless and counterproductive in dangerous situations, and using cruise control in an emergency would be inappropriate, as cruise control is designed for steady, non-hazardous driving conditions. Thus, the appropriate action during an emergency is to slow down, making the selected answer the most accurate representation of the concept.
