To attend to a traffic accident victim, it is essential to **avoid movements of the neck and spine**. This is because any sudden movement can worsen existing injuries.

- **Do not move the injured** unless it is absolutely necessary to put them to safety. If it is necessary to move them, it must be done very carefully, keeping the head, neck, and body aligned, as if they were a single block. This requires the coordination of several people to ensure that no sudden movements occur.

- **Protecting the neck** is crucial. You can use clothing, sand, or your hands to stabilize the injured person's neck, but you should never place anything under the neck.

- **Do not remove the helmet** from an injured person, as this could cause unnecessary neck movements.

- In case of doubt about how to act, it is better **not to touch or move the injured person**. Talking to them and offering emotional support is safer than trying to move them without the proper knowledge.

These measures are essential to avoid worsening the injuries of the accident victim and ensure their well-being until emergency services arrive.
