Atkinson is an English-language surname. The name is derived from a patronymic form of the Middle English Atkin.
Once children outgrow their booster seat (usually at 10 â 12 years old) they can use the adult lap/shoulder safety belt if it fits them properly. Lap portion low over the hips/tops of thighs and shoulder belt crosses the center of the shoulder and center of the chest.
), as Chloe states, allows children to stop using car seats at 40lbs in the back seat provided there are no shoulder belts. It lists other exemptions as well (e.g. if you have no back seats, or your back seats face sideways, or you already have three kids in the backseat, you're allowed to let your six-year-old ride up front).
