Why should a driver avoid lingering beside a large truck?
Blue A is beside the rear half of a large tractor-trailer B in the neighboring lane. Both travel right.
Correct answer: Large blind areas can hide the vehicle from the truck driver.
Why
Passing decisively or dropping back keeps a smaller vehicle out of the truck's extended side blind spots.
