Rear-facing car seats are safe, study shows

A new study finds rear-facing car seats protect children in rear-impact collisions just as well as they protect youngsters in frontal and side-impact crashes.

Researchers at Ohio State University say the rear-facing car seats they tested absorbed crash forces while also supporting the child's head, neck and spine.

Pennsylvania and New Jersey require children to be in rear-facing car seats until they are two years old.
