What should a driver do at the scene of a school bus accident?

Answer: D — Notify all of the above

In the event of a school bus accident, a driver has multiple responsibilities to ensure the safety of those involved and to comply with legal obligations. Notifying the school district is vital as they have a direct interest in any incidents involving their vehicles and can provide necessary support and communication with parents. Informing the California Highway Patrol (CHP) is equally important, as they are responsible for law enforcement and handling crash investigations on highways and public roads, ensuring that safety and legal protocols are followed. Additionally, notifying their employer is necessary because they need to be aware of the situation, possibly for insurance claims, liability issues, and to address the welfare of their employee and any passengers. Informing all relevant parties helps create a comprehensive response to the accident, ensuring all bases are covered for legal, safety, and operational reasons.
