Child Passenger Safety
All states and territories require child safety seats for infants and children fitting specific criteria, but requirements vary based on age, weight and height. This happens in three stages: rear-facing; forward-facing (harnessed) seats; and booster seats.
Many laws require all children to ride in the rear seat whenever possible, and most states permit children over a particular age, height or weight to use an adult safety belt.
First offense fines for not complying with a state's child passenger safety laws vary from $10 to $500. Some states also use driver's license points as an additional penalty for noncompliance.
- Most states, the District of Columbia and Puerto Rico require booster seats or other appropriate devices for children who have outgrown their child safety seats but are still too small to use an adult seat belt safely.
