What is a space cushion in driving?

A space cushion refers to the area around your vehicle that allows you enough distance to react to any emergencies or unexpected situations. Maintaining a safe space cushion is crucial for defensive driving. It provides the driver with a buffer zone to maneuver, change lanes, or stop if necessary without risk of colliding with other vehicles, pedestrians, or obstacles.

Having an adequate space cushion can help prevent accidents by giving you time to assess your surroundings and respond appropriately. This can involve adjusting your speed, changing lanes, or preparing to stop. The concept stresses the importance of awareness and anticipation of potential hazards on the road.

Other options do not encapsulate the true essence of a space cushion. Parking safely relates to vehicle placement, while road safety features and traffic regulation guidelines are more about regulations and physical road designs than the driver's operational management of space around the vehicle. Thus, the emphasis on distance to react effectively characterizes the essential nature of a space cushion in safe driving practices.
