When parking a school bus downhill (on the right-hand side of the road), which of the following should you not do?

When parking a school bus downhill on the right-hand side of the road, it is crucial to ensure that the vehicle is securely positioned to prevent rolling away. Leaving the vehicle in neutral, particularly if it has a manual transmission, does not provide any resistance against movement, which can be perilous when parked on an incline.

This is why engaging the parking brake is essential; it mechanically locks the vehicle in place. Additionally, turning the wheels toward the curb creates a safety mechanism by directing the bus into the curb in the event it does roll. Activating emergency flashers is also a safety protocol that makes the bus more visible to other drivers, especially in low-light situations or inclement weather. Therefore, leaving the vehicle in neutral would not provide any safety measures to keep the bus stationary, making it the incorrect action to take when parking downhill.
