What is a primary reason for inspecting the inside of a bus before driving?
Correct answer: B – To protect riders by checking that aisles and stairwells are clear
The Nevada manual directs drivers to inspect the bus interior for rider safety. Aisles and stairwells must remain clear, and handholds, railings, flooring, seats, emergency exits, and signaling devices must be safe and functional. Securely fastened seats and unobstructed exits help prevent injuries and allow evacuation during an emergency.
