Candidates are evaluated on their ability to recognize life-threatening situations, including significant bleeding, difficulties in breathing, or a loss of consciousness, along with the necessity of prioritizing the treatment of the most severe injuries. This part highlights the importance of maintaining a calm demeanor, making clear decisions, and knowing when to seek professional medical help. Mastering these abilities ensures that school bus drivers can deliver effective initial care, helping to stabilize injured passengers until emergency responders arrive.
