DENVER -- How long should your child stay in a booster seat? You’d be surprised how few Colorado parents know the right answer.
A new study by Safe Kids Worldwide finds that one in four parents admits to not buckling up their child in a car.
That’s why we’re explaining the law to keep your child safe, in our Good Day guide to keeping your family Safe & Secure.
The Insurance Institute for Highway Safety has tested car safety seats using test dummies.
Of the 50 car seats tested, 44 of them were listed as best bets, meaning they were safe and effective.
Four of the seats evaluated were "good bets" and two were not recommended.
"There is a final large category we call check fit, and these are boosters that may do a good job depending on the size of the child and the vehicle. So these are the boosters where we especially urge parents to check how the lap and shoulder belt are doing," said Anne McCartt of the institute.
The fit is key.
Lap belts should lie flat across the child's upper thighs and the shoulder belt cross snugly over the middle of the shoulder.
Not using a seatbelt the right way with a booster seat can actually cause damage in a crash, including spine and internal organ injuries.
