In Illinois, what is required for a child under 8 years old who is less than 4 feet 9 inches tall in a vehicle?

In Illinois, the law mandates that a child under 8 years old who is less than 4 feet 9 inches tall must be secured in a booster seat when traveling in a vehicle. This regulation is designed to enhance the safety of young passengers, as booster seats help position the seat belt correctly on a child's smaller frame. Proper use of booster seats ensures that the lap and shoulder belts fit appropriately, thus significantly reducing the risk of injury in the event of a collision.

By emphasizing that children of this age and height requirement should use a booster seat, the law aims to provide them with the necessary support to maintain their safety while adhering to guidelines that are established for proper vehicle restraint systems.
