Which of the following is considered an improper behavior by a school bus driver?

Using a mobile phone while driving is considered improper behavior by a school bus driver because it poses a significant safety risk. Operating a school bus requires full attention and focus, as the driver is responsible for the safety of the students on board, as well as the safety of other road users. Distractions like mobile phone usage can lead to accidents, as they divert the driver’s attention away from the road and surrounding environment.

In contrast, making eye contact with students is a positive behavior that helps the driver ensure that students are secure and aware of the surroundings. Ensuring students are safe at stops and following traffic signals are also essential duties of a school bus driver that contribute to a safe transportation environment. Therefore, using a mobile phone while driving stands out as an action that goes against the fundamental responsibilities of ensuring safety and compliance with traffic laws.
