DETROIT (AP) - Most new child booster seats earn a top rating from the Insurance Institute for Highway Safety.
The institute, which is funded by insurers, ranked 31 models that went on sale this year. 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.
Britax, Evenflo, Ferrari, Graco, Harmony, Recaro and Safety 1st all had seats on the institute's "best bet" list.
A booster seat should allow the lap portion of the belt to lie flat across the child's upper thighs and the shoulder portion to cross snugly over the middle of the shoulder.
Children should use boosters until they're big enough for adult belts to fit properly.
