Which measurements correctly describe a school bus’s danger zones?
Correct answer: C. – Up to 30 feet in front, 10 feet behind, and 10 feet on each side
North Dakota’s CDL manual describes the danger zone as extending as much as 30 feet from the front bumper, with the first 10 feet being the most dangerous. It also extends 10 feet from each side and 10 feet behind the rear bumper. Drivers must use properly adjusted mirrors to monitor students and objects throughout these areas.
