DETROIT, MI (AP)-- More than half of child booster seats that went on sale this year earned a top rating from the Insurance Institute for Highway Safety.
The institute, which is funded by insurers, ranked 31 new models. Nineteen earned the top rating of "best bet," which means they correctly position a 4- to 8-year-old child to use the regular shoulder and lap belts in almost any car.
The institute said seats have made big improvements since it began testing them five years ago. In all, there are 58 seats ranked on its website, including seats that weren't new in 2013.
The group tested the boosters based on how they positioned a child-sized test dummy to use a car's seat belts.
