Car-Safety.Org Carseat FAQ
Q1: Why should I have my child in a child
restraint? Why do I need a seatbelt?
Motor vehicle crashes are the #1 killer of children from ages 1
to 14. About 50% of these deaths to children under 5
involved children that were unrestrained. Of those that were
restrained, misuse is reported in 80-95% of cases. Injuries
requiring hospitalization are even more common, and many involve the head,
neck, and spine. Some of these injuries are permanent. Child
restraints are VERY effective for reducing deaths and injuries. Also

Q2: Isn’t it safer to hold my baby?
Won’t I be safer if I don’t use a seatbelt and can be thrown from
the car? Won’t it be harder to escape after a crash if I
use a seatbelt?
No. No. No. These are three of many myths used by people to avoid
proper use of child restraints or seatbelts. Statistics prove that
those ejected in a crash are four times more likely to die. The
forces in a crash can be hundreds of pounds or much more, too great for
someone to hold a child safely. Plus, the reaction time needed
in a crash makes it virtually impossible to restrain another
passenger. It is far easier to escape a vehicle if you don’t suffer
the serious head and chest injuries associated with crashes where
seatbelts aren’t used.
Q3: What are the laws for child
Laws can vary by state and municipality. See the IIHS List of State Laws for Vehicle Restraints
or the Inventive Parent Carseat Laws Page.
Q4: How long should children be in a
carseat? In their seatbelts?
Children should be in an appropriate safety seat until the vehicle seatbelt fits them correctly, generally when they are about 8-12 years
old and 4’9″. After that,
they should be properly seated with a lap and shoulder belt.
Children 12 and under should remain in the rear seat. All passengers
should wear lap AND shoulder belts at all times.
Q5: Does the Government give any advice?
Yes. The National Highway Traffic Safety Administration
(NHTSA) has many resources. This website is a great starting
point:NHTSA: Traffic Safety, Child Passenger Safety Program

Transport Canada Child Safety
Q6: How long should a child remain rear-facing?
Rear-facing IS safest. It is best to remain rear-facing to
the weight and height limits of the carseat. Most convertible
carseats have 35 or 40 pound rear-facing limits. The American Academy of
Pediatrics recommends that children be kept in rear-facing seats
for at least 2 years and preferably as long as possible. In all cases,
infants should be rear-facing until they are BOTH one year AND twenty
pounds at an absolute minimum. See these links for more
Rear-Facing Carseats: What you need to know, by
Q7: When should a child be put into a
Many convertible and forward-facing seats have 40 pound weight
limits when using the harness. A convertible or forward-facing seat
with a 5-point harness is the safest option for children who have outgrown their seat rear-facing but have not outgrown their forward-facing carseat. If
a child’s shoulders are above the level of the top slots in their regular
carseat, or the tops of their ears are above the top of the shell, then
they may be able to move to a booster or another forward-facing seat which
accommodates taller children. Usually a child can be moved to a
booster when they are too big for a harnessed carseat, and once they are
able to sit properly in a seatbelt. A child should be in some type
of booster seat until the adult seat belt fits correctly, generally around 8-12 years old and 4’9″ tall (Also see Question 9 below).
Q8: My child is over 40 pounds or too tall
for his carseat, but isn’t mature enough to sit in a seatbelt with a
booster. Are there any options?
There are now many Forward-Facing and Specialty Models for this situation. Models that have forward-facing weight limits higher than 40 lbs include the Britax Boulevard 70 and Marathon 70 convertibles, Britax Frontier 80 and 85, Evenflo Maestro, Graco My Ride, First Years True Fit, Diono Radian, Graco Nautilus, and the Safety First Complete Air.
You may also use a Safe Traffic Systems RideSafer Vest or E-Z-ON Kid-Y harness/booster.
Q9: When can my child be in a regular
seatbelt without a booster?
Children are not ready to be in a regular lap/shoulder seatbelt until:
- They are tall enough so that their legs bend at the knees at the edge
of the seat; and
- They are mature enough to remain seated with their backs flat against
the back of the seat and not slouch; and
- The lap belt sits high on the thighs or low on the hips (NOT on their
- The shoulder belt crosses the shoulder and chest (NOT on their
arms or neck!); and
Each passenger must have their own lap and shoulder belt! Never
allow children to share a seatbelt.
Some organizations will also give limits like 80 or 100 pounds, 4’9″ in
height or 8 years old. These are rough guidelines, not absolute
limits. The criteria above are most important.
Q10: What is the safest carseat?
There is no single safest child safety seat for all children and
vehicles. The safest seat is one that fits your child, fits your
vehicle and one you will use correctly each and every time. Please

Q13: Which carseats are compatible with my
It may be impossible to tell in advance if a carseat will fit tightly in
a particular vehicle. The best advice is to see if you can try the
carseat in your car with your child before you buy it. Also make
sure you have a good return policy in case it doesn’t fit.
Q14: Is a built-in child seat safe?
Yes. Make sure your child is within the age/weight limits listed
in your vehicle’s owner’s manual. If the seat fits your child and is
used properly, it should be very safe and, of course, you never
have to worry about installing it in the vehicle. There may be some
disadvantages to integrated carseats (see #15, below).
Q15: Do I need a separate carseat if my vehicle
has an integrated child seat already?
Maybe. Integrated carseats, especially those with a harness, may have
some disadvantages when used as the primary restraint for a child:
- Emergency personnel often prefer to remove a child in a separate
carseat. This keeps the child immobilized in case of head/spinal
injury and may allow for safer transport in the ambulance.
- Integrated seats do not function rear-facing. Rear-facing is
safest for children, and many separate carseat models allow for rear-facing use to 35, 40 or even 45 lbs.
- Integrated seats do not usually have any form of side impact
protection. Many separate carseats have some form of protection, and
a few have special foam or plastic specifically for side impacts.
Deep wells on the side also help keep a sleeping child’s head more
- Harnesses on some integrated seats can be difficult to adjust, and may
not fit tightly, especially on smaller children. This can lead to an
unsafe fit, and make it easier for a child to remove all or part of the
restraint. Some integrated seats have limited or no harness height
adjustment, a feature found on most separate carseat models. This
means a child may be too tall for an integrated seat well before they
exceed the weight limit.
- Using an integrated carseat as your primary restraint may leave you
without a method to transfer your child to another vehicle (relative,
caregiver, vehicle being repaired, etc).
- The comfort on some integrated seats is far below the level found on
most separate carseats. Integrated seats also tend to be less
comfortable for an adult when folded.
- Optional integrated seats are often more expensive than most
separate child restraints.
Q16: Which carseats have higher slots or fit
larger children? Which ones are narrow or short enough to fit a small
Some seats will accomodate taller children more easily. Also,
it is important that at least 80% of the base of the carseat is in
contact with the vehicle seat. (Some models require that 100% of the base is in contact with the vehicle seat – check your car seat manual.) This website has measurements and
slot height listings for some models:
Measurements and Slot Heights
Q17: Which carseats have the most
The best way to compare features is to try carseats yourself in person. You may find some features
simply aren’t important to you.
Q18: Should I buy a carseat with a harness or a
A 5-point harness is considered safest. T-shields and overhead
tray shields are no longer produced and may be less safe, especially for small infants. Also
SafetyBeltSafe Best Car Seat
Q19: Which other features are important?
Many features can enhance safety or convenience. See this feature
guide for some information:
Carseat Buying Guide
Q20: Are combination systems with strollers and
carseats any good?
The carseats in combination travel systems are all tested and
safe. You may find you don’t get all the features you want in the
carseat or stroller when buying a system. On the other hand,
some infant seats have convenient bases that allow you to move the
carrier from one car to another car to a stroller without waking your
infant. Only you can decide if one is right for your situation.
Q21: My baby is N years old and weighs X
pounds. What carseat should I buy for my model vehicle?
Specific recommendations are beyond the scope of this FAQ. For
recommended carseats, please visit CarSeatSite.Com and our Recommended Seats. Finally, these questions are
also very appropriate for our
Q22: I have a very small newborn. What seat
Check the manufacturer’s instructions for the minimum weight. For premature or
very small infants, you can also try a car bed or infant seat with low or no minimum weight limit.
For a list of seats, see Car
Seats with Best Fit for Preemies and Small Newborns from Safe Ride News. While many convertible seats
have limits as low as 5 pounds while rear-facing, a typical rear-facing
infant seat may be a better fit and be more convenient as well.
Carseats with shields are not recommended for small infants.
Q23: Where can I find a car bed or carseat
for a child with special needs?
Currently, the best resource for special needs carseats is a local
hospital. You should also be able to contact a local fitting station and a
certified technician should be able to put you in contact with someone who
can direct you to a source for these carseats. These links have
List of Special Needs Carseats. (PDF)

Indiana University School of Medicine: Special Needs Transportation
Q24: Which carseats can be used on an
Carseats should have a label with FAA approval for use on an
airplane. Most infant and convertible models have this label.
Most booster seats, safety vests and carseats over 16″ wide cannot be used
on an airplane. Once a child is 40 pounds, they can generally use
the regular seatbelts on an airplane. The CARES Harness is specifically
designed for children 22-44 pounds and is attached to an airplane seat and seatbelt. Please check the instructions
for your carseat for specific details. It is always best to buy a
separate ticket for your child to guarantee a seat; some airlines offer
discounts for small children. Many airlines prefer a carseat to be
put in the window position; contact your airline for specific rules.
Q25: How many years can I use my carseat?
Many manufacturers now put “expiration” dates on their carseats.
Six (6) years is the general recommendation. At most, 10 years is
the accepted maximum lifetime of a carseat. The reasons for these
limits involve possible degradation of the plastic shell and other parts,
the possible loss/breakage of parts, and the fact that older seats will
often not meet current government safety standards.
Q26: Are used carseats safe to use?
If you are unable to verify that the carseat has never been involved in
a crash, do not use it. Above that, you should inspect it carefully
to make sure all the parts and labels are intact, and that there are no
visible stress marks. You should also verify that the stickers with
the manufacturer, model number and date of manufacture are legible.
You must also have the owner’s manual, or get a copy from the
manufacturer. Finally, you need to make sure the used carseat has
not been recalled (or if it has, that the appropriate corrections were
made). Older seats may not meet current safety standards.
Older seats may also be less convenient and more difficult to use,
and may lack the latest safety features. If there is any doubt on
the condition or history of a used carseat, please destroy it
completely and permanently (using a saw or otherwise) and purchase
a new one. Our community forum offers an environment with safety advocates to buy, sell and trade used car seats at Carseat Swap.
Q27: My carseat was in an crash. Can I
still use it?
The general recommendation is NO. You must replace it and
destroy the old one so it can never be used again. Some insurance
companies will reimburse for carseats involved in a crash, and
they are required by law to do so in some states. Please
call the manufacturer of your carseat if you have any questions.
You should also contact your car dealer after a crash, as it is very
likely that the seatbelts, LATCH/tether anchors and integrated child seats
may also need to be replaced.
The NHTSA has some guidelines for using carseats after a crash:
NHTSA: Child Restraint Re-use After Minor Crashes
Q28: A review I read online said
my carseat is not a good one. Should I get a new one?
Keep in mind that many reviews are written by parents who have no
training and little knowledge about Child Passenger Safety. Such
comments and reviews may or may not be accurate. If in doubt, please
consult a carseat
technician. You may also find professional car seat reviews from certified child passenger
safety technicians and instructors at CarseatBlog.
Q29: The IIHS or Consumer Reports said my booster may be
unsafe! What should I do?
The IIHS rates booster seats for correct fit using a dummy in various vehicles.
They do not actually peform any crash testing or compile any injury data. So, their
results may not be relevant to the booster you use with your child, in your vehicle.
The Safest Way to Boost ‘Em for more information on IIHS ratings. Also,
with any booster model, a child can put slack in the
seatbelt. The shoulder belt guides of certain boosters
can catch the shoulder belt, preventing the retractor from taking in the
slack. This may even vary from one vehicle to another vehicle, depending on the location
of the seatbelt retractors. These boosters may still be used safely!
Proper supervision is always necessary for squirmy kids or escape
artists. Many children can compromise their safety by unlatching
seatbelt and harness buckles, escaping various types of carseats and by
putting shoulder belts behind their backs while in boosters. With
proper installation, instruction and supervision, the problem shoulder
belt guides identified by Consumer Reports can often still be used safely.
First, make absolutely sure to follow the instructions in the carseat
manual and make sure there is no slack in the seatbelt during the
trip. On taller children, these guides may not even be needed since
the shoulder belt may already fit correctly without the guides.
Finally, some vehicles have locking seatbelt mechanisms. If you
pull the seatbelt all the way out, it will lock, taking up all the
slack as it retracts and then preventing the child from pulling the
belt out again (check your owner’s manuals to see if this is allowed).
Q30: Consumer Reports rated my carseat very
low. Is it safe?
All carseats currently sold must pass minimum government
requirements. Consumer Reports has its own methodology and does not
discuss how they derive their crash test ratings or how their ratings
relate to the risk of injury. They also conceal their results in
colored circles, which don’t tell you exactly how much safer a top-rated
model is compared to a lower-rated one. Also, a carseat that worked for
the dummies on the car benches at Consumer Reports may not fit well in
your vehicle or with your child. A carseat should be safe if it fits your child,
fits your vehicle, and you use it correctly every time. Also, please see our Carseat Buying Guide.
Q31: My child won’t use a carseat/booster.
My child escapes his carseat. What can I do?
Some children can twist out of harnesses at an early age. Others
can easily undo the buckle mechanism. Children may also be able to
put too much slack in a seatbelt, and some children don’t want to use a
child restraint or seatbelt at all. Driving is a dangerous
activity, and like any other, it requires proper supervision at all
Parents can try many things. You can try calling the
your carseat to see if they have a buckle that requires more force to
release, or a 2-piece chest clip instead of a “paperclip-style” chest
clip. Using a seatbelt yourself sets a good example. Refusing
to put the car in motion unless the child stays in their restraint is
another. Also, try to keep your child entertained or distracted if
possible, and NEVER make an exception and allow them not to use their
child restraint. For severe cases, you can try a safety
vest by E-Z-On
may be more difficult to remove.

Q33: Is my carseat tight enough?
Grab your carseat at the base, where the seatbelt goes. The base
should not move more than an inch (1″) side-to-side or
front-to-back. Some movement at the top of the seat is normal,
though a tether
will reduce this movement in forward-facing carseats.
Ideally, you want the child coupled as tightly as possible to the harness
system and carseat, and the carseat coupled as tightly as possible to the
vehicle with the seatbelt or LATCH system. When you do this, the
child gains all the benefit of “ride-down time” provided by the crushing
frame of the vehicle in a crash. With a loose installation of any
kind, the child gets less ride down time and suffers a more severe crash
into the harness system. Also see this
definition of ride-down time.
Q34: The top of my rear-facing carseat moves
easily. Is that unsafe?
No. Most rear-facing car seats are not designed to be tethered.
The top of the seat will be able to twist and rotate toward the back of
the vehicle. This is normal. If the carseat rotates DOWNWARD
into the seat cushion significantly, you may try to put your weight on it
and install it a bit tighter.
Q35: I can’t get it tight enough, what can I
- Make sure you have read the owner’s manual thoroughly and are using
the correct path for the seatbelt.
- Check your vehicle’s owner’s manual for information on the
seatbelts. Yours may have a locking retractor mode. On some
cars, you can pull the seatbelt all the way out and it will lock as it
retracts. You can then put your weight on the carseat as it retracts
to take up all the slack.
- Make sure to put your weight on the seat as you install it.
Rocking back and forth a little may also help. As you apply weight,
pull the slack from the lap portion of the seatbelt. If
possible, brace your back against the roof of the vehicle to add
downward force. In some cases, a second person is helpful to
buckle the belt while the first applies force on the carseat.
- In some vehicles, especially large SUVs and vans, you can move the
vehicle seat back and recline the back of the seat. Do this, then install
your carseat. When you have it as tight as you can get it, then move
the vehicle seat forward and move the seat back upright again. This may help
get it even a little tighter, especially for a forward-facing
carseat. Make sure you check your vehicle seat and child restraint each time you use it, in
case someone else moves the vehicle seat back or reclines it.
- Try a tether
for a forward-facing seat, and make it tight.
- You may need a locking-clip
consult the owner’s manual for you vehicle and carseat. Incorrect
use of these clips can be very dangerous.
- If you need further detail, try the CarSeatSite.Com
Installation Tips, consult a local technician or post
your question to our forums.
Q36: My carseat is tight, but I’m worried that it
might gouge the fabric or leather in my car. What can I do?
Unfortunately, a good installation does put pressure on your vehicle’s
interior fabric. You may put a THIN towel or mat under your carseat
to prevent gouges. You must NOT put thick towels or any compressible
material under a forward-facing carseat, as this can reduce the safety of
Q37: What is LATCH? Is it safer? Does
my car or carseat have it?
LATCH (also ISOFIX) is not necessarily safer than using seatbelts to
install a carseat. It may make it easier to get a safe
installation. LATCH stands for Lower Anchors and Tethers for
CHildren. Most newer vehicles and child seats have this system.
For more information, see our comprehensive guide:
Car-Safety.Org LATCH and
Q38: What are tethers? Can I use one with
Tethers are straps that prevent the top of a carseat from moving
forward in a crash. They may also increase overall stability.
Many newer cars and carseats are compatible with tethers or can have
them installed. Tethers allow newer carseats to meet stricter
safety standards. See:
Car-Safety.Org LATCH and Tether Information
Q39: Can I use my tether strap when the carseat
Generally, NO, unless it is specifically mentioned in your
manual. In the USA, some models manufactured by Safeline Sit-n-Stroll, Britax,Combi and Diono may use a tether when rear-facing. You can find some
instructions for tethering the Britax models in the
Britax Online Instructions.
Q40: What is the safest position for my
The center of the rear seat is usually safest since it is farthest from a
possible side impact, but only if your carseat fits well in that position.
Any position in the rear seat is acceptable unless prohibited by the vehicle or
child seat owner’s manual. The seat behind the passenger may be slightly safer
than the seat behind the driver, since it allows you to unload the child on the curb
side, allows you to see your child more easily from the driver’s seat and is very
slightly less likely to be hit on that side in a side impact. There is also a
small risk that a front seat-back could collapse in a severe rear-end
crash, and the passenger seat is less likely to be occupied by a
heavy adult who could crush a carseat in this situation. The
front seat is generally not advised for children 12 and under, especially if an
active airbag is present.
If you have more than one child, the safest arrangement may not be
obvious. Usually, it is preferable to put the child with the most
protection in the outboard location; rear-facing seats offer the most
protection from side impacts. These types of questions are very
appropriate for our forums.
Q41: My car has a fold-down armrest in the rear
seat. Can I install my carseat in front of it?
Generally, yes. Though there
appears to be no evidence that this is unsafe, at least one
company, Evenflo, used to recommend that you do NOT install many of their carseat
models in front of a fold-down armrest. Some vehicles may have had this recommendation, also. Please consult the owner’s
manual of your vehicle and carseat before making this decision.
Q42: My car only has lapbelts, what can I
Lapbelts alone are not safe for any passenger, though they are better
than no restraint at all. Some suggestions:
- A lapbelt is usually fine for installation of a carseat. This
includes most infant, convertible and forward-facing carseats with a
harness. In rare cases, a lapbelt that does not keep a
carseat tight may need a special belt-shortening
- A lapbelt is NOT adequate for a booster. Children in booster
seats must have a lap AND shoulder belt for protection.
- There are some forward-facing and specialty models for larger children
who must sit in a lap only belt position.
- Some vehicle manufacturers will also install a shoulder belt
in some older models. This may be the best solution. Because of limited availability, you
will need to contact your manufacturer or dealer for details.
Q43: Can I install a carseat in the
side-facing jump seats in a pickup, or a rear-facing seat in a
Carseats and boosters should NEVER be installed in side-facing
jump seats. Unfortunately, that means that children under 8 years
old (about 80 pounds) should not ride in these types of seats.
Children should never ride in the cargo area of a pickup.
Rear-facing seats in wagons vary. Usually, you will not be able
to install a carseat, but children in seatbelts may be seated there in
some models. Please consult your owner’s manual or vehicle
manufacturer for recommendations. Some newer wagon models may have
weight limitations for the rear-facing seat, and it may be best not to use
rear-facing bench seats in older models at all.
Q44: Can I install a carseat/booster in a
position that does not have a headrest?
The child MUST have some type of head support behind the head, to at
least the midpoint of the skull, or around the tops of the ears.
This head support is provided by infant seats, convertible seats,
forward-facing only seats with a harness and high back booster seats.
If a child is using a backless booster, or is old enough to use the
lap/shoulder belts alone, then they should not be seated in a position
without a headrest if the midpoint of their head is above the top of the
vehicle seat. If no rear seating position with a headrest is
available, then they should be in a high-back booster model (some of
these models are rated to 100 pounds). Whiplash is a serious injury,
even in a minor rear-end crash. Adults require adequate head
support just as children do.
Q45: Can I put my carseat in the front seat of my
Airbags can be deadly to infants in rear-facing carseats, and to
children 12 and under using the seatbelts. The front seat is
generally not recommended for children 12 and under. The airbag MUST
be disabled if you must use a rear-facing child seat in the front.
Some vehicles without a rear seat, especially pickup trucks, have an
on/off switch for this purpose. If a child must ride in the front,
you should also move the front seat as far back as it will go.
Please only consider a front seat if no other option is available.
NHTSA Tips on Air Bag Safety
Q46: How far should my carseat be
reclined? Should it tilt to one side?
It is recommended that newborns and young infants sit in a
rear-facing carseat at a 45 degree angle (maximum). Some infant
carseats have a built-in level indicator. Older infants should have
less recline once they are able to support their heads.
Forward-facing carseats should not be reclined. Though some
forward-facing and convertible models are approved in a semi-reclined
position, this recline does concentrate crash forces in the crotch so an
upright position is preferred.
A slight tilt in not a problem in forward- or rear-facing seats.
This tilt should not be so severe that it lifts part of the base of the carseat
off the vehicle seat. This issue is generally more common with rear-facing carseats,
and in some cases a locking
clip can be used if nothing else works to reduce the tilt caused
by a locked shoulder belt pulling up on the carseat.
Q47: Is it OK to put a towel under my carseat to
adjust the angle?
You may put a tightly rolled towel or foam pool “noodle” under the
front of a rear-facing carseat (near the crack of the vehicle seat) to get
the necessary recline. You must not put a noodle, thick towels, or
any compressible material under a forward-facing carseat.
Q48: My rear-facing carseat is touching the
back of the seat in front of it? Is that OK?
Please consult the owner’s manual of your carseat. For most
carseats, this is not a problem and may actually improve safety. You should also check your vehicle manual to confirm that it allows a rear-facing car seat to touch the back of the seat in front of it; this may interfere with the “smart” air bag sensors in some newer vehicles.
Best practice from the NHTSA training manual states, “A rear-facing seat
can be installed so it rests against the back of the vehicle seat ahead if
not counter to manufacturers instructions….If the gap is small or the
child is on the heavy side, it is much better to be already touching any
forward structure prior to a crash than to hit it during the crash.
Resting against a forward seat back is only one way to achieve these
Q49: What is a locking clip? Do I need
Some vehicle lap and shoulder belts pull and retract freely, with no
locking mechanism. A locking clip allows you to clip together the
lap and shoulder portions of a seatbelt, and helps prevent the seat
belt from becoming loose before a crash. This will fix the lapbelt
at one length to hold a carseat. The locking clip is always
installed on the side of the carseat near the buckle, no more than one
inch away. If the locking clip is on the wrong side, it can actually
cause more slack during a crash, and the forces can cause it to bend or
fly off (also a serious hazard!). Consult your carseat or vehicle
owner’s manual for details. If your vehicle has locking seatbelts,
you usually do not need a locking clip. One exception is for a
rear-facing carseat, where a locking clip may be used to prevent a severe
tilt in the carseat.
A regular locking clip is not load bearing and cannot withstand crash
forces. Its function is to maintain a proper pre-crash position of
the lap and shoulder belts. In a crash, the seatbelt retractor
will lock the seatbelt and carseat in the proper position.
For more details, see these links:
CarSeatSite.Com Locking Clip Information
BuckleUpNC Information on Seatbelt Systems
Q50: I only have a lap belt. Can I use a
locking clip to make it tight?
No. In the rare case that you need to shorten a lap-only
seatbelt, you need a special, heavy-duty belt-shortening clip.
Contact the manufacturer of your vehicle or carseat to obtain
Improper use of these clips can be dangerous. For more
details, see these links:

NHTSA Information on Heavy Duty Belt Shortening
Q51: Can I use aftermarket products to help
install carseats or position seatbelts?
In general, you should not use any products not recommended by the
manufacturer of your carseat or vehicle. Despite the claims of
some companies, these products are NOT regulated by any federal
standard, and have not been tested or certified by carseat
manufacturers. This is not to say these products do or do not work,
but your choice to use them might compromise the safety of your
Q52: Can I use an infant head support? Is it
OK to put a padded cushion under the child for comfort?
Generally, NO. Unless such items come with the carseat or are
recommended by the manufacturer of the carseat as an accessory, do not use
them. Aftermarket pads and cushions are not tested with the seat
and any compressible material inside the harness may allow for more slack
in the restraint. With a small infant, it is usually OK to put a
rolled towel or receiving blanket along the sides of the head (outside
the harness straps) to keep it upright. You may also put a rolled
towel between a small infant and the crotch strap if there is a large gap,
though you should never put towels or pads under a child in a carseat.
Q53: Which harness slots should I use?
Please consult the carseat manual first for specific
instructions. When rear-facing, you should use the harness slot
which is at the level of the child’s shoulders or slightly below.
When forward-facing, use the slots at the level of the child’s shoulders or
above. For more information on correct harness use, please also
Correct Harness Use from CarSeatSite.Com
One catch is that you MUST use the TOP slots on some older convertible
carseats when they are forward-facing regardless of how high they are.
This is because the lower slots are not
reinforced to hold in the forces of a crash. This does not
apply to carseats that are forward-facing ONLY, such as “toddler” or
“combination” seats. Most other seats also have at least one
additional reinforced lower slot.
Q54: How tight should my harness straps
Harness straps should be snug with no slack, but not so tight as
to be uncomfortable. The top straps should be on the shoulders, and
some prefer to say that you should not be able to take a pinch or get
more than a finger in between the shoulder and the strap. The lower
straps in a 5-point harness should be fairly tight across the thighs (not
on the tummy). A tight harness can prevent ejection, and also can
increase the ride-down time to reduce the chance of crash injury.
Q55: Does it matter if my harness straps are all
Yes. The more the straps twist, the less area of strap is
available to restrain the child in a crash. This means more pressure
will be applied to the child, and could result in burns or more serious
injury. It is a good idea to untwist the straps after each
use. Some models have straps that do not twist.
Q56: Where should the chest clip (harness
retainer tie) be on my child?
It should be across the chest, at armpit level. It should not be
on the neck or tummy. This clip itself does not protect during a
crash. Its job is to keep the harness straps in the correct
position before a crash.
Q57: Can my child wear a winter coat in their
Generally, no. For safety, the harness straps must remain tight on the child’s
shoulders regardless of any clothing. You can put
a blanket over the child, OUTSIDE the harness straps or put your
child’s coat on backwards after they are in the seat. For infants
in cold weather, an aftermarket “cozy” that zips over the infant carrier
rather than fitting under the child is another solution.
Q58: Is my child too tall or heavy for his/her
Please consult the manual for your carseat first. The weight
limits are also listed on decals attached to the carseat. Most
current infant seats have at least 22 pound weight limits, and many models
go to 30 or 35 pounds. Most current convertible seats have
rear-facing limits of 35 or 40 pounds. Some convertibles
have 40 pound limits when front-facing, though many models have increased forward-facing weight limits.
Some forward-facing models are also limited to 40 pounds using the built-in harness.
“Combination” seats are carseats with internal harnesses that can be removed then converted to belt positioning boosters.
(See instructions for the maximum weight limit for the harness.)
Height limits may be listed in the owner’s manual. Otherwise,
rear-facing children in an infant seat or rear-facing convertible seat are too tall if the top of their head
is within one inch of the top of the seat shell. It may also be an inconvenience if they
are tall enough to kick the seat back of your car, but this is not
unsafe. A child is too tall for a forward-facing harnessed
carseat if their shoulders are taller than the highest slots, or if the
top of their ears are above the top of the carseat shell.
Q59: Is it OK to leave the handle upright on my
Please read your owner’s manual. For some models, you must put the handle down
(in the horizontal position) while it is in the car. In a crash, infant seats can rebound
into the vehicle seat. This can break the handle, injuring the
infant or another passenger. Some manufacturers do allow the handle to
remain upright on some of their models. Please check your manual to be sure.
Q60: I think my infant or carseat is too
hot. What can I do?
If you are comfortable, it is likely your child is comfortable,
too. If you have air conditioning, put it at maximum fan speed and
in “recirculate” mode, and aim some vents toward the rear. If the
sun is on your child, put a very thin white towel or receiving blanket
over them or put up the canopy in an infant carrier. Put a similar
blanket or cover on the carseat if your car is in the sun all day.
You can also try purchasing window sunscreens to block the sun; the safer
ones attach with static and have no hard metal rods. As a last
resort, try tinting your car’s windows as your state laws
permit. Tinting may also help keep shattered glass from breaking
apart in a crash.
Q61: Is it safe to install my carseat
near an airbag?
First, you MUST check the carseat and vehicle
owner’s manuals to see if they specifically mention installing the carseat
in a seating position with an airbag. Some carseat manufacturers do
state that their carseats should not be installed in a spot with an active
airbag. In addition, rear-facing carseats should NEVER be placed in
a front seat with an active frontal airbag. Forward-facing carseats
and boosters may sometimes be placed in the front with an active airbag,
but only if absolutely necessary and not prohibited by the owner’s
manuals. In these cases, the vehicle seat should be moved all the
way back. Also see:
NHTSA Tips on Children and Airbags
Currently, side airbags are generally not considered a risk to
children in correctly used child restraints. In fact, children in properly
installed and used child restraints should gain a safety benefit from side impact
airbags unless otherwise indicated in an owner’s manual.
A possible risk is to child passengers seated out of position: leaning
on the door, face on the window, head sleeping on a pillar, etc.
This would be most relevant to children in boosters who are not
seated properly, and to children not using any type of seatbelt or
restraint. Side curtain airbags should be even less risk, as
they are higher and inflate with somewhat less force. In general, it
should be OK to place a child in a harnessed carseat (front or rear
facing) in a rear seat position with an active side airbag, as long as the
owner’s manuals for the carseat and vehicle do not prohibit such
placement. Automakers have agreed to a rigorous set of testing
procedures based on voluntary compliance to standards established in a
working group chaired by the IIHS These standards include tests of
all types of side airbags with 3yr, 6yr, and 5th percentile female dummies
in a variety of normal and extreme seating positions. While these
voluntary standards will apply to some model year 2002 and many model
year 2003 and later vehicles, they may not apply to earlier models. Also
