Key takeaways from Safety Behind the Wheel Foundation

A specialized child restraint is a crash tested bed, seat, vest or securement system for a child who cannot use a regular car seat well.
Most children with special health care needs can still ride in a standard car seat. In one hospital study, about three in four did [1].
Babies who cannot breathe well sitting semireclined may need a car bed for a while, after a hospital screening [2].
A child in a hip cast needs a travel plan before surgery. One study found most casted children rode in a setup that was not right for them [3].
Choose with your child’s medical team and a certified child passenger safety technician who has special needs training [4].
Never add padding or gadgets the restraint maker has not approved, and strap down every piece of medical equipment [1, 2].

Safety Behind the Wheel Foundation built this guide from American Academy of Pediatrics (AAP) policy, Children’s Hospital of Philadelphia (CHOP) guidance, National Highway Traffic Safety Administration (NHTSA) resources, federal child restraint rules and published hospital and crash test studies. Every source is listed at the end.

What a specialized child restraint is

A specialized child restraint protects a child who cannot ride safely in a regular car seat, booster or seat belt. The reason may be a cast, a breathing problem, weak muscle control, a medical device or challenging behavior. Its job is the same as any car seat: hold the child in place and spread collision forces over the strongest parts of the body.

These products fall under the same federal safety standard as everyday car seats. Federal Motor Vehicle Safety Standard 213 (FMVSS 213) defines a car bed as a restraint that holds a child lying flat, on the back or stomach [5]. It defines a harness as a restraint made mostly of straps, with no rigid seat [5]. The standard even sets its own crash test limit on head movement for harnesses and restraints designed for children with physical disabilities [5].

An updated version, Standard 213b, applies to child restraints made on or after December 5, 2026. It keeps the car bed category [6]. Before you buy or borrow any specialized product, ask whether it is certified to the federal standard.

The main types are below.

Comparison compiled by Safety Behind the Wheel Foundation

Main types of specialized child restraints

Type	Who it may help	What to watch
Car bed	Babies who must lie flat, often after failing a car seat screening [2]	Installed crosswise on the vehicle seat and used until the baby can handle a regular seat [2, 5]
Cast friendly seat	Children in hip (spica) casts	Easier fit does not always mean better protection in a collision [7]
Large medical or positioning seat	Older or bigger children who need head and trunk support	Must fit the child, the vehicle seat and the tether setup
Harness vest	Children who cannot sit in a seat or need a different harness	In one crash test with a casted dummy, a vest had the highest head injury score [8]
Wheelchair tiedown and occupant restraint	Children who must ride seated in a wheelchair	Chair secured to the vehicle, child belted separately [9]

Who may need one

The American Academy of Pediatrics (AAP) has a policy statement on transporting children with special health care needs. It gives guidance for children with airway problems, orthopedic conditions or surgery, developmental delays, unusual muscle tone, challenging behaviors and digestive conditions [10]. Premature babies have their own screening process, covered below.

A diagnosis alone does not mean your child needs special equipment. In one study, technicians with special needs training observed 294 children with special health care needs as they left a children’s hospital garage [1]. About 75% rode in a standard car seat, and 82% of the seats evaluated were an appropriate choice [1].

The bigger problem was how seats were used. Only about 27% of the seats checked had no mistakes [1]. About one in four drivers had changed the seat in some way, and roughly one in five children would have benefited from more positioning support [1].

So start with one question: can a regular seat, used correctly, do the job?

Build the right team first

Choosing a specialized restraint is a team decision. Your child’s doctor or therapist knows the medical needs. A certified child passenger safety technician (CPST) knows how restraints and vehicles fit together.

Not every technician has extra training in this area. The national certification program’s technician FAQ mentions a course called “Safe Travel for All Children: Transporting Children with Special Health Care Needs” [4]. When you contact a technician, ask whether they have taken it or similar training.

Technicians teach correct installation and use, and their program tells them to stay within their role as health educators [4]. Medical calls, such as whether your baby can sit semireclined, belong to the medical team.

NHTSA, the federal road safety agency, says certified technicians will check your car seat for free in most cases and show you how to use it [11]. Start by asking your child’s hospital or clinic whether they have a technician with special needs training.

Babies who need to lie flat: screening and car beds

Some newborns do not breathe well when sitting semireclined, the way they ride in a rear facing seat. Hospitals check for this with a car seat tolerance screening. Babies born before 37 weeks usually need one. So may babies with medical conditions that make that position hard to tolerate [12].

During the screening, staff watch the baby’s heart rate, breathing and oxygen level. The baby sits in your own car seat for 90 to 120 minutes [2]. If the baby does not pass, a second screening follows. If that one also fails, the doctor may recommend a car bed. The baby then travels lying flat until they can handle a semireclined seat [2].

Babies born closer to term can fail too. In a study of 918 late preterm babies born from 2013 to 2017, 4.6% failed the screening [13]. The authors noted that many hospitals screen only babies born earlier, so practice varies [13]. Ask before discharge whether your baby will be screened.

A car bed works differently from a seat. Under the federal standard, a car bed is installed crosswise, at a right angle to the length of the vehicle [5]. In the crash test, the dummy’s head and torso must stay inside the bed [5]. A car bed takes up much of the back seat, so practice the installation before the baby comes home. Think of it as a bridge, not a destination.

Children in hip and body casts

A spica cast is a hard cast that covers the hips and one or both legs. Children may need one after hip surgery or a broken thigh bone. Many standard seats will not fit around it.

Families often end up with the wrong setup. In one study of 31 children in 35 spica casts, a physical therapist found that none could ride in the family’s own car seat [3]. Twelve were advised to travel by ambulance and 23 to use a specially made seat. Only 23% followed the advice, and children in 69% of the casts rode in a way that fell short of the hospital’s protocol [3].

Crash tests offer useful lessons. Researchers put a double leg spica cast on a test dummy the size of a 3 year old and tested several restraints [8]. All passed the federal head and chest limits. But the booster seat had the highest neck loading. The vest had the highest head injury score, and its chest compression went past proposed federal limits [8]. Seats with harnesses did better than an easy to fit booster [8].

A second study used a 1 year old dummy in rear facing seats [7]. Seats designed for casts made it easier to seat the dummy. But they put more load on its body than conventional seats that could fit the cast [7]. In one test, a cast seat set at a recline its maker allowed went past the federal chest limit [7].

The lesson is that an easy fit is not the same as good protection. Ask for the restraint plan before surgery, not on discharge day.

Positioning seats, vests and wheelchairs

Some children need more support than a regular seat gives. They may have low muscle tone, poor head control or a body that tires and slumps. Large medical seats add side support and a harness that fits bigger children. Vests hold a child to the vehicle seat with straps.

Many families try to add support with towels or foam. Australian researchers tested that idea in 40 frontal sled tests [14]. Padding placed under the restraint to tip it back raised head injury measures. Towels in several places, including behind the head, let the head move farther and raised chest measures [14]. Firm foam, or a tightly rolled towel secured at one spot, had little effect [14].

Australian guidelines recommend firm foam in some cases. U.S. child safety experts give simpler advice: add nothing the vehicle and restraint makers have not allowed [2]. Safety Behind the Wheel Foundation gives families the same advice.

Some children must ride seated in their wheelchair. Then the chair must be secured to the vehicle, and the child needs a separate occupant restraint [9]. Voluntary industry standards from RESNA and ISO set design and performance criteria for these systems, aiming for protection similar to a regular vehicle seat [9]. Ask the supplier whether the chair is designed and tested for use as a seat in a moving vehicle. After a collision, have the wheelchair and tiedowns checked.

If your child rides a school bus or medical van, ask that the restraint and equipment plan be written down and shared with drivers and aides.

Choosing a restraint: a step by step routine

Work through these steps in order.

Name the need. Ask the care team, in writing, whether your child can sit upright, sit semireclined or must lie flat.
Try the simplest option first. Ask whether a conventional seat, used correctly, can meet that need.
Measure your child. Record weight, height and seated height, plus hip width with any cast.
Check the vehicle. Find the lower anchors and tether anchors, and decide where an adult can sit to watch the child.
Do a hands on fitting in your own vehicle with the technician, before surgery or discharge when possible.
Plan for equipment. Decide where each device will be strapped down and confirm how long its battery lasts.
Practice loading, unloading and releasing your child quickly in an emergency.
Set a date to recheck fit.

Where to get one and how to pay

Specialized restraints come through fewer channels than ordinary car seats: the restraint manufacturer, medical equipment suppliers and authorized dealers of adaptive products. For tether anchor hardware, ask the vehicle dealer’s service department what the vehicle maker approves.

Hospitals sometimes lend them. In one hospital loaner program for children in spica casts, a therapist chose each child’s restraint [15]. The restraints cost the hospital $150 to $750 each, while an ambulance ride cost $1,200 [15]. The authors called the loaner program a practical model [15]. Another research team suggested loaner programs, wider insurance coverage and financial help for families [3].

Ask your child’s care team about health insurance or Medicaid help and what paperwork it needs, such as a prescription or a letter of medical need. Coverage varies by plan, so get answers before you buy.

Be careful with used products. A used restraint may have been in a collision, recalled or past its use by date. If you borrow one, get the manual and register it with the maker. NHTSA notes that registration lets the maker contact you directly about recalls [11].

Using it right on every trip

A restraint helps only when it is used every time, the right way. NHTSA reports that 39% of children killed in car accidents in 2024 were unrestrained [11].

Loose equipment can fly forward in a collision and hit someone. Yet in the hospital study, only 8% of medical equipment was properly secured [1].

Never leave your child alone in the vehicle, even for a minute. A child who cannot move or speak cannot call for help.

Common mistakes and caring for the restraint

Watch for these common problems.

Choosing by fit alone. An easy fit is not proof of crash protection [8].
Adding towels or foam behind the head, or under the restraint to tip it back [14].
Reclining more than the care team advises. In one cast seat test, a recline within the maker’s range still went past the federal chest limit [7].
Changing the restraint or its harness [1].
Using a car bed or vest longer than needed.

Keep the manual with the restraint. Check the use by date, look for frayed straps and cracked plastic, and clean only as the manual directs. Recheck fit after growth, surgery or a new device.

After any collision, follow the maker’s rules on replacement. If the restraint was a loaner, tell the lender about the accident.

Frequently asked questions

Can I use a regular car seat with extra padding instead?

A regular seat is often right, but homemade padding is risky. In sled tests, padding under a restraint or behind the head made some injury measures worse [14]. Add nothing the restraint and vehicle makers have not allowed [2]. If your child slumps or tilts, ask a trained technician and your child’s therapist about other options.

My baby failed the car seat screening. Will we always need a car bed?

Usually not. A car bed is meant for the period before your baby can handle a semireclined seat [2]. Ask the medical team when to repeat the screening in a regular seat. Until then, use the car bed every trip and keep an adult in the back seat [2].

Is a vest safer than a car seat for a child in a cast?

Not always. In one crash test with a casted 3 year old dummy, the vest had the highest head injury score of the restraints tested [8]. A vest may still be the only workable option for some children. Let the medical team and a trained technician decide with you.

Can my child ride in their wheelchair?

Sometimes, if the chair is designed for it. The chair must be secured to the vehicle, and your child needs a separate occupant restraint [9]. Ask the supplier whether the chair is tested for use as a vehicle seat, and ask your child’s team whether moving to a crash tested car seat is possible.

Will insurance pay for a special needs car seat?

Ask your child’s care team what your health plan or Medicaid program needs, such as a prescription or a letter of medical need. Also ask about hospital loaner programs. One hospital program lent restraints to children in spica casts and called the approach practical [15].

How do I find a technician with special needs training?

Start with your child’s hospital, clinic or therapist. NHTSA’s car seat page links to a technician locator [11]. When you call, ask whether the technician has taken the course on transporting children with special health care needs [4].

The bottom line

Recommendation from Safety Behind the Wheel Foundation

Safety Behind the Wheel Foundation encourages families to choose a restraint for the child’s real medical need, not for an easy fit. A specialized child restraint has one job: to keep a child with medical or physical needs as safe as any other child on the road. The best result usually comes from a careful process, not a special product. Start with the medical need, try a regular seat first, and add special equipment only when it is needed.

Plan early with your child’s medical team and a technician trained in special needs. Then use the restraint the same way every trip, strap down every device, and recheck fit as your child grows.
