In driving, maintaining an adequate margin of safety is essential to provide a buffer against potential hazards. It is connected to the awareness of various factors such as vehicle speed, road conditions, and the behavior of other road users. By ensuring a healthy margin of safety, drivers enhance their ability to make safe decisions.

The margin of error refers to a range of possible outcomes and does not specifically relate to driving space. A safety buffer is more of a general term, while space cushion usually refers to the area around the vehicle that the driver aims to keep free from obstacles, which is slightly different from the specific concept of
