Which of the following is classified as an emergency maneuver?

Swerving to avoid a collision is classified as an emergency maneuver because it involves a rapid and often instinctive reaction to a sudden and unexpected hazard on the road. This situation typically requires immediate action to prevent a potential accident, showcasing the driver's ability to respond effectively under pressure.

Unlike the act of turning left at an intersection or changing lanes smoothly, which are considered routine driving actions, swerving is a reflexive response necessitated by an imminent danger. Slowing down for a school zone is also a normal precaution that does not fall under the category of an emergency maneuver, as it is a standard part of road safety practices rather than a reaction to a sudden risk. Therefore, the classification of swerving to avoid a collision as an emergency maneuver is rooted in the need for quick thinking and immediate action in a potentially life-threatening situation.
