**Whiplash** is a common injury in traffic accidents, especially in **rear-end collisions**. This type of collision occurs when one vehicle crashes into the back of another. During this impact, the body of the driver or passenger is pushed forward while the head stays back, causing a sharp neck movement similar to a whip.

- In rear-end collisions, the sudden and violent movement of the neck is what causes whiplash.
- This type of accident is more frequent on **straight roads** and not on curves, and it usually occurs during times of heavy traffic, such as at the end of the workday or during rush hours.

Therefore, it is important to maintain an adequate **safety distance** between vehicles to reduce the risk of rear-end collisions and, consequently, of suffering whiplash.
