Installing and Using Child Safety Seats and Booster Seats
Correct restraints for children riding in motor vehicles depend on the child's age
and size. Restraints to keep a child safe in the car include:
The key to keeping your child safe is to use an age-appropriate child restraint that
is correctly installed and used.
Infant and child safety seats come in many shapes and sizes. The best child safety
seat for a family is the one that is correct for the child's age, weight, and size.
It's also one that's easy for the parents or caregivers to use, fits in the family
vehicles' seats, and works the vehicles' seat belts or lower anchor and tether system.
The American Academy of Pediatrics (AAP) has advice for using child safety seats:
Babies and toddlers should ride in a rear-facing car safety seat in the back seat,
for as long as possible. That means until they reach the top weight or height allowed
by their seat. Check your car safety seat instructions.
Don't put a rear-facing car safety seat in the front passenger seat of any vehicle
that has a passenger-side front air bag. This practice prevents the risk for death
or serious injury from impact of the air bag against the safety seat. All children younger than 13 years should ride in the back seat.
Premature and small babies should not be placed in car safety seats that have shields,
abdominal pads, or arm rests. These could hit a baby's face and neck during an impact.
Ask your child's healthcare provider if you have questions about the correct seat
for your baby.
In rear-facing car safety seats for babies, set shoulder straps in the lowest slots
until the baby's shoulders are above the slots. The harness must be snug. Put the
car safety seat's retainer clip at the midpoint of the baby's chest. Don't put it
on the abdomen or in the neck area. Check your safety seat instructions.
Make sure the car safety seat is at the correct angle so that the baby's head does
not fall forward. Wedge a firm roll of cloth or blanket on either side of the baby
to keep them secure. Check the instructions from the maker of your child safety seat.
Convertible car seats can be used rear-facing. They can be converted to forward-facing
for older children when they outgrow either the weight or height limit for rear-facing.
Most convertible seats have height and weight limits that will allow children to ride
rear-facing for 2 years or more. Check your car safety seat instructions.
Use a booster seat when the child has outgrown a convertible safety seat or forward-facing
seat, but is too small to fit correctly in a vehicle safety belt.
Use a belt-positioning booster seat that has a combination lap and shoulder belt.
The National Highway Traffic Safety Administration advises against a booster seat
that has a small shield instead of a shoulder belt.
The infant safety seat
Infant safety seats are often small and portable. They are for babies up to age 1
and weight 35 pounds. Infant seats are rear-facing. They may come with a 3-point or
a 5-point harness. Some infant seats come with detachable bases that can be left belted
into the vehicle. This means you don't need to install the seat each time. Some bases
also are adjustable to correctly recline the baby. Some infant seats are rear-facing
only. Others convert to a forward-facing position when your child reaches a certain
height or weight. Always check the car seat instruction manual for how to correctly
use the seat.
The child safety seat
Babies and toddlers should ride in a rear-facing car safety seat for as long as possible.
That means until they reach the top weight or height allowed by their seat. Child
safety seats can be convertible or forward-facing.
Convertible seats. Most convertible seats have height and weight limits that will allow young children
to ride rear-facing for 2 years or more. Check your car seat manual to know when you
can switch the seat from rear-facing to forward-facing. Check the car safety seat
maker's instructions for how to adjust the shoulder straps and use seat belt correctly.
Forward-facing seats. These are for children who have outgrown the weight or height limit for their rear-facing
or convertible seat. These children should use a forward-facing seat with a harness
for as long as possible. This means up to the weight or height limit set by the car
The booster seat
When your child is taller or weighs more than the limit for their forward-facing car
seat, switch to a belt-positioning booster seat. Booster seats help raise up your
child so that the vehicle's seat belts fit correctly.
Always put booster seats in the back seat of the vehicle. There are two types of booster
High-back booster. This is a booster seat that helps protect the head and neck in back seats that don't
have head restraints. The vehicle's lap and shoulder belts are used to secure the
Backless booster. This is a booster seat that raises up the child up so that the vehicle's lap and shoulder
belts correctly restrain the child.
Checking your car seat
Some of the most common mistakes in installing or using child safety seats include:
Safety belt doesn't hold the seat in tightly or is not in locked mode
Harness straps are not snug or positioned correctly
Harness retainer clip is not at armpit level
Locking clip is not used correctly
Car seat was recalled and not repaired. This includes booster seats.
Babies are placed rear-facing in front of an active air bag
Children are turned forward-facing before the height or weight limit listed by their
Carefully read your vehicle owner's manual and the instructions that come with the
child safety seat. Check that the seat is correctly installed. Use the seat correctly.
Always keep the child's safety seat instruction manual in the car for easy reference.
Here are some questions to ask yourself:
Is your child riding in the back seat? The back seat is the safest place in a crash.
Is your child facing the correct way? Babies and toddlers should ride in a rear-facing
car safety seat for as long as possible. That means until they reach the highest weight
or height allowed by their seat.
Is the child safety seat held tightly in place by the seat belt or lower anchor and
Does the harness buckle snugly around your child?
Does your older child fit correctly in the vehicle's seat belts? The shoulder belt
should rest over the shoulder and across the chest, not the neck. The lap belt should
fit low and snug over the upper thighs, not the belly. The child should be tall enough
to sit with knees bent at the edge of the seat without slouching.
Replacing child safety seats and seat belts after a crash
Once a vehicle has been in a severe crash, replace child safety seats and seat belts.
They may have become stretched or damaged. All child safety seats are replaced by
insurance companies. Always check with your child safety seat maker for any questions
about the safety of your child's seat.
When car seats are recalled
Sometimes child safety seats are recalled for safety reasons. It's important to register
your car seat so you can be told if the seat is recalled. To check if your child safety
seat has been recalled, call the seat's maker or the National Highway Traffic Safety
Administration Vehicle Safety Hotline at 888-327-4236. If the seat has been recalled,
you will be told how to fix it, or how to get parts to fix it.
