Observation, Speed & SpaceStandalone practice
If another vehicle follows too closely, what is a defensive response?
On a divided road with two eastbound lanes, blue A is in the left lane. Silver C follows A closely, and B is farther ahead. The right lane is empty in the illustrated segment. The opposite carriageway is outside the view. Positions alone do not establish time gaps.
Correct answer: Increase space ahead and let the driver pass when safe.
Why
Creating more space ahead provides room for gradual braking and reduces the chance that a tailgater's error becomes a collision.
