Observation, Speed & SpaceStandalone practice
A vehicle is following you too closely. What is a safe 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: Slow down and let the vehicle pass
Why
Creating a larger forward cushion and letting a tailgater go by reduces the chance that sudden braking will cause a rear-end crash.
