What is essential to review with your student helpers before the trip?

Answer: B — Emergency procedures

Reviewing emergency procedures with student helpers before a trip is crucial because it ensures that everyone knows how to respond in case of unexpected situations or emergencies. This preparation builds confidence and can significantly enhance safety during the journey. Understanding emergency procedures includes discussing what to do if there's an evacuation, how to alert the driver to a problem, and how to assist fellow students if needed. While navigating the route, discussing seating arrangements, and talking about maintenance tasks are important aspects, they do not hold the same level of critical importance as knowing how to handle emergencies. In situations where quick action is necessary, having a clear plan can make all the difference in ensuring the safety of the students on the bus.
