How can a driver assure the effectiveness of a head restraint?

To ensure the effectiveness of a head restraint, placing it as close to the head as possible is essential. The primary purpose of a head restraint is to minimize the risk of whiplash and neck injuries during a rear-end collision. When the head restraint is positioned correctly, ideally just a few centimeters behind the head, it serves to prevent excessive movement of the head backwards, helping to reduce strain on the neck.

Having the head restraint too far away leaves the driver or passenger unprotected, increasing the likelihood of injury during an accident. Therefore, proper adjustment close to the back of the head maximizes the protective capability of the restraint, providing the best defense against potential injuries.
