Why should a driver avoid moving closely in front of a large truck and then braking?
Passenger car A is ahead of tractor-trailer B in the same lane. No cut-in path or braking instruction is shown.
Correct answer: A heavy truck needs more distance to stop than a passenger vehicle.
Why
Large vehicles need extra stopping space, so cutting in closely removes the safety buffer their drivers created.
