What should be done immediately after checking the driver's safety in an accident?

After checking the driver's safety in an accident, it is essential to prioritize safety and health by calling 911. This is the appropriate response because it ensures that medical assistance and emergency services are dispatched if there are any injuries involved. Timely medical intervention can be critical, and having professionals on the scene can assist in assessing the situation and providing necessary care.

While other actions, such as calling the safety and security hotline or reporting to the general manager, are important steps that may follow, they do not address the immediate need for medical assistance. It’s crucial to first ensure the health and safety of all individuals involved before proceeding with additional reporting or notification procedures.
