What is an "emergency stop"?

An "emergency stop" refers specifically to a sudden halt made in response to an immediate danger that poses a risk either to the driver, passengers, or other road users. This type of stop is often vital in preventing accidents or collisions as it enables the driver to quickly react to unforeseen hazards, such as a pedestrian unexpectedly entering the roadway or another vehicle suddenly braking. The key aspect of an emergency stop is its urgency and the need for immediate action to maintain safety.

In contrast, other options describe different scenarios related to stopping. A gradual stop to avoid skidding emphasizes a more controlled deceleration, which is suitable for maintaining stability rather than responding to an immediate threat. Stopping at a traffic signal is a routine and expected action governed by traffic laws, and stopping for passengers to exit is a planned operation, typically done safely and at designated areas. These do not embody the essence of an emergency situation where quick response is paramount.
