What will happen for rear seat passengers in a car crash?

In a car crash, rear seat passengers can experience serious injuries due to a lack of protection compared to front seat occupants. They may be propelled forward or sideways, potentially striking the front seats or other passengers. Additionally, if they are not wearing seatbelts, the risk of being ejected from the vehicle increases significantly. Proper use of seatbelts and safety features, such as airbags, can help mitigate these risks.
