Why should you maintain open space around your vehicle?

Correct answer: C – It provides distance to react to an emergency
A space cushion provides distance for braking or steering when a hazard develops. Maintain room ahead and behind, stay near the middle of your lane, and use an appropriate time interval behind the vehicle ahead. Increase that following interval when weather, traffic, pavement, or vehicle conditions make stopping more difficult.
