Which of the following is NOT a recommended action when a school bus approaches a stop?

When a school bus approaches a stop, the focus is on ensuring the safety of the students getting on and off the bus. Speeding up when there is a vehicle approaching contradicts this principle of safety. It can create a dangerous situation where the bus and the approaching vehicle might not have adequate time to react to each other, potentially leading to accidents involving students.

Activating hazard lights, ensuring all students are seated, and checking mirrors for obstacles are all actions that promote safety. Hazard lights alert other drivers that the bus is stopped, while making sure students are seated helps prevent accidents inside the bus. Checking mirrors ensures that the area around the bus is clear and that students can safely board or exit the bus without the risk of oncoming traffic. These practices align with the primary goal of protecting the safety of children as they travel to and from school.
