Why should you add extra following space behind a large truck or bus?
Blue A follows a long white truck B along a divided highway roadway. Both face right, with an open gap between them.
Correct answer: The extra gap improves your view and gives more time if the heavy vehicle changes speed.
Why
A generous gap behind a large vehicle preserves sight distance, reaction time, and visibility to its driver. A truck can block your view of a developing hazard, and its driver may not see a vehicle close behind. More space lets you observe beyond it and respond without sudden braking.
