If you arrive first at a collision scene involving other vehicles while driving a school bus, what is your first action?

When you arrive first at a collision scene while driving a school bus, the initial priority is to ensure safety for yourself and others involved. Parking the bus in a safe place allows you to create a secure environment, separating your vehicle from the potential hazards of the collision. It prevents further accidents and keeps the area manageable for first responders when they arrive.

While calling for assistance, providing first aid, and turning on hazard lights are also important actions to take, they can be done after ensuring your vehicle is parked safely. Positioning the bus can also help to direct traffic or contain the situation, which is crucial in emergency situations to minimize risk and manage the scene effectively. This makes it the correct first response in handling a collision scene.
