What Are the Child Safety Car Seat Laws in Each State?

All 50 states and the District of Columbia have laws governing the use of child safety seats. Child passenger safety laws require the use of approved car seats, booster seats, and appropriate child safety restraints while traveling in a motor vehicle. Once a child is able to use an adult seat belt, they fall under general seat belt laws. Because laws differ from state to state, it’s important to understand the car seat laws where you live.¹

Because rear-facing car seats provide better protection in front-end collisions, the American Academy of Pediatrics recommends placing children in a rear-facing car seat for as long as possible, only switching to a front-facing seat when the child outgrows the car seat’s rear-facing weight and height restrictions.³ 

But if you live in one of the following states, you may be required by law to keep your kiddo in a rear-facing style until a certain age.^1,4  This makes choosing an extended rear-facing model like the Evenflo EveryStage, Britax Boulevard, or Graco 4Ever even more important.

No matter where you live, we recommend following proven safety standards like those set by the American Academy of Pediatrics.
