Safe Ride for Baby: Car Seat Safety

Babies need child safety seats to ride safely in the car. Your baby should be in a child safety seat facing the rear of the car until he or she reaches either 2 years of age or the maximum weight or height allowed for the car seat.

Types of Seats

Car beds are for premature, very small, and special-needs infants who need to lie flat.

Infant-only car seats are small and lightweight, and face the back of the car only. These are easy to use with babies 17 to 22 pounds. Use this kind of seat until the baby's head reaches the top rim of the seat. Check the label for size and weight limits.

Convertible car seats are larger seats used rear- or forward-facing in the car.

For a newborn, choose one with a 5-point harness, not a harness with a tray shield. Many models can be used rear-facing to 30 or more pounds. Rear-facing is the safest way for your baby to ride. Keep your child in a rear-facing care seat until he or she is 2 years old.

Talk to your baby's doctor or call the Safety Restraint Coalition at 425-828-8975 or 1-800-BUCK-L-UP (1-800-282-5587) for information about the best seat or bed for your small baby.

Safe Car Seats

The best and safest seat to buy is one that:

Don't choose by price. A higher price doesn't mean you get a safer seat.

Warning About Airbags

Put babies in the back seat! If your vehicle has a passenger-side airbag, never place a child safety seat in front. The airbag opens with such force it could kill your child.

All children under age 13 should ride in the back.

Installing a Safety Seat

The car's safety belt must hold the car seat tightly to the seat of the vehicle. If the belt is loose, the safety seat won't protect your child. Safety belts tighten in different ways. Read your car owner's manual and the labels on the safety belts.

Make sure the baby's seat can't move forward more than 1 inch. (A rear-facing seat can tip toward the vehicle's seat back.)

Fitting the Harness

Adjust the harness to fit snugly on the baby (one finger can fit under harness at chest), over the shoulders and between the legs. Dress your baby in clothes that keep legs free.

Don't use blankets, a heavy snowsuit, or other bulky items under the straps. They keep the harness from being tight enough to hold your baby in a crash. To keep your baby warm, tuck a blanket over him after you buckle the harness.

Put the harness straps in the lowest slots. Straps should be in slots at or just below your baby's shoulders in the rear-facing position.

Use a harness retainer clip to keep straps on your baby's shoulders. Put the clip at mid-chest, armpit level.

Check the harness fit often. Adjust the fitting as your child grows and wears different outer clothes.

Seating for a Small Baby

Seating for an Older Baby

When your baby has reached the maximum height and weight allowed for the rear-facing car seat, he or she can ride in a safety seat that faces forward. The American Academy of Pediatrics recommends keeping children in a rear-facing car seat until he or she is at least 2 years old. Keeping your baby in a rear-facing seat as long as possible is safest for your baby.

Move your child to a booster seat when he or she reaches 40 pounds, or when:
