Final answer:
The margin of safety is not a fixed distance of 10 to 15 seconds ahead of your vehicle. It is a concept used in driving to describe the space you have available to react and stop your vehicle safely.
Step-by-step explanation:
The statement is not accurate. The margin of safety is not a fixed distance of 10 to 15 seconds ahead of your vehicle. Instead, the margin of safety is a concept used in driving to describe the distance between your vehicle and the vehicle in front of you.
The margin of safety depends on several factors including your speed, road conditions, and reaction time. It is typically recommended to maintain a minimum margin of safety of at least 3 seconds or a distance of at least 3 car lengths. This allows you enough time and space to brake and avoid a collision.
