  • Children under age 2 AND 30 pounds to ride in a rear-facing car seat
  • Children under age 4 AND 40 pounds to ride in a harnessed car seat
  • Children in booster seats are to remain in their booster seat until reaching the height or weight maximum listed by the manufacturer (There is no booster seat with a height maximum lower than 4’4”).

What is the Right Seat for My Child?

As research and technology in child passenger safety evolves, the answer is frequently changing. In short, the 'best' car seat is the one that fits your child, fits your vehicle, and is one you will use correctly every time your child is in the car.

In short:

  • Under the age of 1 – Children must always ride rear-facing. Rear-facing is not just for babies! The American Academy of Pediatrics (AAP) has long recommended that―infants ride in rear-facing car seats, and in 2018 the AAP updated that recommendation to encourage rear-facing for as long as possible, until a child reaches the highest weight or height allowed by the manufacturer. Most convertible car safety seats have limits that will permit children to ride rear-facing past the second birthday.
  • Ages 1 through 3 – Keep your children rear-facing for as long as possible in either an infant or rear-facing convertible seat. They should remain rear-facing until the height and weight limit for rear-facing mode on the convertible car seat has been reached. This may result in many children riding rear-facing to age 2 or older.
  • Ages 4 through 7 – Keep children in a forward-facing seat with a harness to the maximum height and weight limit allowed by the seat. Then transition them to a booster seat.
  • Ages 8 through 12 – Keep children in a booster seat until they reach the upper height or weight limit of the booster seat or until they are big enough to fit the criteria for fitting appropriately in a seat belt. The shoulder belt should lie across the shoulder and chest, not cross the neck or face, and the lap belt must lie across the upper thighs not the stomach.
