Sharing the RoadStandalone practice
You have passed a large truck and want to return to its lane. Why must you leave a generous clear gap in front of it?
Correct answer: A truck needs much more room to stop, and a cut-in removes it.
Why
Do not cut closely in front of a truck after passing. Leave a generous gap and make sure the truck is safely behind before returning. A heavy vehicle may need much more distance to slow or stop.
