Final answer:
Children under the age of 15 are generally required to use seatbelts or age-appropriate car seats to ensure their safety in vehicles. The specific regulations may vary, but the overall intent is to minimize injuries and societal costs associated with car accidents involving children.
Step-by-step explanation:
The question concerns whether children not over the age of 15 are required to wear a seatbelt. It is important to recognize that the specific laws regarding seatbelt use may vary by country and state. However, in general, societal and governmental regulations emphasize the safety of children in vehicles. Typically, there are laws in place that mandate the use of seatbelts for children. For instance, young children may be required to use car seats while older children should use booster seats and eventually transition to standard seatbelts when they are big enough.
These laws are created to safeguard young individuals in cars and serve to protect society from the consequences of injuries sustained in automobile accidents. An injured child or teenager may require long-term medical care, which can become a responsibility for society as a whole if the injury is severe enough.
In summary, while exact age can vary depending on location, children and teenagers up to the age of 15 are generally required to wear a seatbelt or be secured in an age-appropriate car seat or booster for their safety.
