Car seats and boosters are designed to keep your kids safe while on the road.
But if they're not installed right, they can cause even more injuries.
A new survey shows parents make significant mistakes when putting in car seats.
Some of the biggest errors include using the wrong harness slot, not securing the seat well enough and improper lap belt placement.
The most important thing to know is the type of seat to use depending on your child's age and size.
Experts say kids one through three should ride in rear-facing car seats.
Children four to seven should be in forward-facing seats with a harness until they reach certain weight and height limits.
And kids ages eight to 12 should be in booster seats until they're big enough to use seat belts.
