How does wearing a seatbelt prevent injuries?

Wearing a seatbelt helps prevent injuries by restraining occupants during a collision, minimizing their movement and keeping them securely in their seat. This reduces the risk of being ejected from the vehicle and limits the force of impact against the interior of the car. By distributing crash forces across stronger parts of the body, seatbelts significantly lower the likelihood of severe injuries. Overall, they are a crucial safety feature designed to protect both drivers and passengers in the event of an accident.
