The **failure to provide assistance** is a crime that occurs when a person does not help the victims of a traffic accident, as long as they can do so without putting themselves in danger. This includes not stopping to help or not notifying emergency services to come to the accident scene.

- **Helping the victims**: If you witness an accident, you must try to help the victims or at least seek help for someone else to do so. Not doing so, when possible, is considered a failure to provide assistance.

- **Collaborating at the accident scene**: It is important to collaborate to prevent further damage or injuries and help restore safe traffic conditions. If you cannot help directly or emergency services are already present, it is best to keep moving to avoid obstructing the accident scene.

- **Reporting the accident**: If you cannot provide direct assistance, it is crucial to inform the authorities so they can send help. Not doing so is also considered a failure to provide assistance.

Therefore, the correct answer is that the crime of failure to provide assistance is committed by people who do not stop at an accident where help is not organized.
