STEP 1 – Rear-Facing Infant Seats
for children from birth to at least one year and at least 20 pounds.
STEP 2 – Forward-Facing Child Safety Seats
for children at least one year old and 20 pounds until they reach 40 pounds, typically around age four.
STEP 3 – Belt-Positioning Booster Seats
for children over 40 pounds but younger than eight years old and not yet 4-feet 9-inches tall. A booster seat positions a child so the belt fits properly and the child isn't thrown from the car or truck in a crash.
for older children large enough for a seat belt to fit properly, typically children at least 4-feet 9-inches tall. Remember--children under 12 years old should always ride in the back seat, where they are safest.
