A child who is 7 years of age or older and weighs 60 pounds or more can use which of the following?

A child who is 7 years of age or older and weighs 60 pounds or more is permitted to use either a regular seat belt or an approved booster seat. The key point is that at this age and weight, the child has the physical development to properly fit into a seat belt system designed for adults. The use of a booster seat is also an option, as it helps position the seat belt correctly across the child's body to ensure proper safety and comfort.

Using a seat belt correctly is crucial in providing adequate protection in the event of a collision. The criteria of age and weight ensure that the child can safely utilize the vehicle’s standard safety features while minimizing the risk of injury. Therefore, the correct option acknowledges the flexibility in choice for parents or guardians, allowing them to utilize either safety measure as appropriate for their child’s size and the vehicle's configurations.
