Why is it important for emergency exits to stay closed during transit?

Emergency exits must remain closed during transit primarily to enhance passenger safety. Keeping these exits properly secured reduces the risk of unauthorized access to the vehicle, which can pose a safety threat to passengers. When exits are closed, it helps maintain the structural integrity of the bus, preventing passengers from falling out in case of sudden stops or accidents. Furthermore, it minimizes the potential for distractions that could occur if exits were opened during transit. Thus, the safety of all passengers is prioritized by ensuring that emergency exits remain closed while the vehicle is in motion.
