Correct answer to question 34 (General Knowledge): To avoid a crash or violation from hitting a low bridge or exceeding a road's weight limit

Why

A commercial vehicle's height and weight can make an ordinary route illegal or dangerous, so checking for low bridges and weight limits ahead of time avoids a serious crash or citation.
