To act correctly in the event of a traffic accident, it is essential to follow the **PAS rule**, which stands for **Protect, Alert, and Rescue**. This rule establishes the order of actions that should be taken to ensure the safety of everyone involved and minimize damage.

- **Alerting emergency services** is the **first link** in the assistance chain. This involves calling the emergency number 112 to report the accident. It is crucial to provide details such as the number of injured or if there is a fire, so that emergency services can prepare adequately.

- **Protecting** the accident area and **rescuing** the injured are steps that follow after alerting. However, alerting is a priority because it allows professionals to arrive as quickly as possible to provide appropriate medical care.

- Acting quickly in the first 10 minutes is crucial to **save lives** and **prevent the situation from worsening**. Therefore, alerting emergency services is the initial and most important step in attending to an accident.
