How frequently are bus evacuations required to occur?

Bus evacuations are required to occur annually because this timeframe ensures that all drivers and students are regularly trained in safety procedures. The focus is on familiarizing everyone with the evacuation process, which is critical in emergency situations. Annual training allows for sufficient practice, reinforcing the importance of readiness and ensuring that all individuals involved are familiar with the specific steps to take for a safe evacuation.

Having more frequent requirements, such as every semester or quarterly, could lead to diminishing returns due to potential fatigue and reduced focus from participants. Conversely, allowing evacuations to occur less frequently than annually may lead to a decline in retention of the procedures, which is why the annual requirement strikes a balance between practice and relevance.
