Counseling about car safety shouldn't hit the brakes when a child graduates from an infant seat or booster seat. Here is what parents need to know to help children ride safely from birth through adolescence.
It is that simple: Traveling in a motor vehicle is the most dangerous thing children do, causing more death and disability than any other activity. Motor vehicle crashes are the number one cause of death among children at every age after their first birthday. In 2001, 4,593 American children 18 years of age and under died as a result of riding in a car,1 and more than 610,000 were injured.2 The majority of deaths and serious injuries are readily preventable.
Pediatricians play a pivotal role in guiding parents through the growth and development of their children, providing advice on everything from teething to toilet training. Although pediatricians often discuss child passenger safety with the parents of their youngest patients, the subject comes up less often as children age.3 Moreover, some evidence suggests that physicians are poorly trained to give specific advice on the safest ways for children to ride in cars.4 Yet parents are interested in receiving more advice from pediatricians5and the correct advice could easily save a child's life.
What is the safest way for children to travel in the car? How do safety recommendations change as children grow? How important are booster seats? When is it safe for a child to ride in the front seat? What guidance should the pediatrician be giving when teenagers begin learning to drive? This article addresses these and other passenger safety issues.
Keeping abreast of all the permutations of infant safety restraints and devices is virtually impossible, even for the most committed pediatrician. However, knowing the basics is crucial. Giving a parent misinformation about the safest way to transport a child could result in significant injury. The first tenets of child passenger safety are that all children need to be properly restrained while riding in a vehicle and that this requirement begins at birth.
Because of their relatively large head size and weak necks, healthy young infants (over five pounds) should ride in a rear-facing child safety seat. Facing backward allows the distribution of deceleration forces over the infant's entire trunk in a crash, subjecting the spine to less extreme flexion and resulting in fewer fractures, dislocations, and deaths.6 It is a misconception, however, that when an infant can sit up and support his own head he is ready to sit forward-facing in the car. Rear-facing is recommended because of the incomplete ossification of infants' vertebrae and their lax connecting ligaments, not because of weak neck musculature.7 The American Academy of Pediatrics (AAP) recommends, therefore, that infants ride facing backwards until they are both 1 year of age and weigh more than 20 pounds.8
The proper position for the rear-facing infant is semi-reclined at an angle of approximately 45°. This position helps support the infant's head to prevent slumping and airway obstruction. Two kinds of seats can be used: infant-only seats, designed to face rearward exclusively, and convertible seats that can be turned in either direction. Many infant seats come with a separate base, which makes carrying the baby in the seat and reinstalling it in the car easier. It may be necessary to place a bolster (such as styrofoam "noodles" that are used in swimming pools) between the base of the safety seat and the cushion of the car's seat to achieve the proper angle; convertible seats often have kickstands. Many have a level indicator that indicates proper positioning.
The upper limit of a child's weight for an infant seat is often 20 pounds, so a convertible seat must be used when the child approaches 20 pounds but is not yet 12 months old. Parents of children who weigh more than 12 pounds at the 4-month check-up should be counseled to consider switching to a rear-facing convertible seat. It is important to review weight limits on all safety seats; each has been tested to some maximum weight.
Although installing the safety seat properly in the vehicle may be difficult, assessing the installation should be easy. The seat should be tightly bound to the vehicle seat with no more than one inch of play in both the front-to-back and side-to-side positions when the safety seat is pushed or pulled forcefully. Because seat belts have "give" to allow normal motion and only lock up in the event of a crash, the belt holding the safety seat in place must be locked into position. Depending on the vehicle, a locking mechanism may be built into the clip itself. If not, an extra "locking clip" may be needed to keep the vehicle's safety belt tight (Figure 1). Locking clips typically come with the safety seat but also can be purchased separately. To avoid head injury, the handles and canopies on infant seats need to be in the down position during travel.
The National Highway Traffic Safety Administration (NHTSA) has responded to the difficulty of installing child safety seats by formulating new regulations that require all passenger vehicles after model year 2002 to be equipped with tethering systems (Lower Anchors and Tethers for Children, or LATCH) that make installation of car seats much easier.9 This increasingly available technology allows the car seat to be slid into place with two clicks, one for the bottom anchors and one for the tether. New child safety seats come equipped with tethers.6 When in doubt about car seat installation, your best choice is to send the family to a "car seat technician," someone formally trained by the NHTSA to install safety seats and perform safety checks. Car seat technicians are available across the United States. (For more information on car seat installation and availability of local car seat safety checks, go to www.nhtsa.dot.gov/people/injury/childps/CPSFitting/Index.cfm .)
The infant must be securely strapped into the child safety seat. The straps should fit snugly so that the gap between the strap and the child's clavicle is no greater than one finger width. The plastic chest clip should be at the level of the child's armpit, where it helps to keep the shoulder straps in place. In a crash, loose straps or low chest connectors can lead to ejection if the infant's sloping shoulders slip out of the straps. The straps should be free of twists and positioned in the lower slots of the car seat for the rear-facing position (Figure 2).
Although all 50 states mandate safety seats for infants and their use has become fairly routine, misuse is all too common. The NHTSA funds an observational study to evaluate restraint usethe National Occupant Protection Use Survey (NOPUS)which recently showed that 99% of infants under 1 year of age ride in a safety seat. Unfortunately, 15% of the infants were placed in the front seat, and only 32% were properly positioned facing rearward.10 Of the 100 infants under 12 months of age who were fatally injured while riding in a motor vehicle in 2001, 29 were in the front seat and only 42 were riding in a car seat.11 These findings call attention to the need for more parent education about using infant seats.
It is worth noting that safety seat use is much lower (as low as 19%) among low-income and minority populations than other groups in the US.12 Parents in these populations may require additional motivation from the pediatrician to use a safety seat. The reasons for low safety seat use are complex and may be specific to the family or cultural community. A common thread, however, appears to be the belief that the need for the infant to bond with caregivers is more important than keeping the baby in a safety seat when traveling. In addition, parents may get conflicting advice from advisors who mistakenly believe infants are safest when carried in a mother's arms, even in the car. Pediatricians can play a role in overcoming these concerns by reassuring parents that bonding can occur at other times than while riding in the car and that the safest way to calm a crying child while traveling is to park the vehicle before removing the infant from a safety seat. It may also help to remind parents of a basic principle of physics: In a crash at only 30 miles an hour, a 10-pound infant becomes a 300-pound force straining to escape the caregiver's arms (force = mass x acceleration). No one can reasonably expect to keep such a projectile contained.
For parents who do not have a safety seat, money is the primary issue 70% of the time.1 Safety seats can cost more than $100, and children need a series of new seats as they grow. Pediatricians need to ask parents if cost is the problem and know what alternatives to buying a seat are available within the community. Local hospitals may have giveaway or lending programs for infant seats; car care retailers may make available lower-cost car seats of all sizes; or the local Safe Kids Coalition ( http://www.safekids.org/ ) may have or know of low-cost or rental options.
In vehicles with a front passenger airbag, the infant seat must be placed in the back seat of the vehicle because the rear-facing position of the safety seat places the infant's head directly in the path of a deploying airbag (Figure 3). As of January 1, 2003, 22 infants had died as a direct result of deployment of the front passenger airbag. All were sitting in rear-facing safety seats in the front passenger position and all were killed in crashes that, experience shows, would otherwise have been survivable.13 Vehicles that do not have a full-size rear seat are now equipped with a turn-off switch for the front passenger airbag, which must be in the OFF position when an infant is riding in the front seat. Families with several children who need to place a child in the front seat should choose the oldest child. If that child is younger than 12 years, the parents can have an airbag turn-off switch installed. (For more information on turn-off switches for air bags, see http://www.nhtsa.dot.gov/airbags/ .) [Editor's note: For a discussion of front airbags and children, see "Airbags and children: A mixed blessing" in the April 2001 issue.]
Side airbags are a new phenomenon and are not regulated by the NHTSA. They can be placed in either the front or the rear seat and deploy out of the roof rail, the side of the seat, the window rail, or the armrest. Children seated close to a side airbag may be at risk of serious or fatal injury14; this may be particularly true for infants in seats that are very close to or touching the side door. The NHTSA has asked automobile manufacturers to ship vehicles with the side airbags deactivated. The purchaser can ask to have them activated after they have been advised of the potential risk to children seated near them. Parents should discuss with the dealer the type and position of side airbags before purchasing a new car.
Once a child is 1 year old and weighs more than 20 pounds, she may be placed in a forward-facing safety seat. Toddlers are still safer facing backward, so there is no need to make the switch until the child has reached the maximum weight for the rear-facing seat. Convertible seats can be turned around and reinstalled. (Some safety seats are designed and tested to be forward facing only.) Because each seat is tested for certain weight limits, it is important to check the manufacturer's information booklet to ensure that the toddler and the seat are a match. Forward-facing seats are installed in the upright position and should pass the same secure fit test as infant seats (no more than one inch of play in any direction). Some vehicles have integrated car seats. They are typically suitable for toddlers, but weight limits vary by maker; details should be available in the vehicle owner's manual.
When a child is facing forward, the harness straps must be placed through one of the upper sets of slots so that they come over the top of the child's shoulders. Straps in these slots not only serve to hold the child in position, but also spread crash forces over the part of the seat that is engineered to withstand themthe reinforced portion of the back of the seat. The chest clip should be connected to both straps on every trip and sit at about the level of the child's armpits. Just as with an infant seat, the harness straps must be snug. The parent should be able to slide no more than two fingers between the straps and the child.
Toddlers should remain in a safety seat until they reach at least 40 pounds. However, they can stay in this type of seat as long as it fits well: The top of the child's ears should be below the top of the back of the safety seat, the shoulders should be below the uppermost strap slots, and the child's weight should be below the maximum manufacturer's recommendation.
The same issues with airbags exist for toddlers as for infants. Toddlers, like infants, should not ride in the front when the vehicle has a functioning front passenger airbag. A recent study by the NHTSA found a high rate of misuse of turn-off switches for these airbags. The switch was left on inappropriately in 25% of cases involving passengers 1 or 2 years of age, and the misuse rate increased with increasing age. Moreover, the switch was off 18% of the time when an adult was in the passenger seat.15 Although there is little hard evidence, toddlers may be at risk of injury from side-impact airbags, and the switches for these airbags should probably be turned off.
Laws in all 50 states mandate the use of safety seats for children to 4 years of age. This does not, however, mean the seats actually are used or that they are used properly. The NOPUS study mentioned found that although 94% of 1- to 3-year-olds were in some child seat, 10% were riding in the front seat and only 62% were using the correct, forward-facing toddler seat.10 Of the 361 toddlers between 1 and 4 years of age who were killed in a car crash in 2001, 94 (26%) were riding in the front seat and 143 (39.6%) were not restrained at all.16
An important message to convey to parents about all child safety seats is that, if the seat has been subjected to a crash of any severity, it must be thrown awayeven if they think that it "looks OK." The crash has stressed the components of the seat, and plastic and metal parts are not as strong as they were before and will not protect the child optimally in the next crash. This is one reason a used car seat may not provide maximum safety. A second reason is that car seats sometimes get recalled, and unless the parents have registered the seat, they probably will not find out there was a problem until their child is injured. Child safety seats can be registered through the manufacturer or at www.nhtsa.dot.gov/people/injury/childps/csregfrm.pdf so that parents receive notification of problems. Pediatricians need to actively encourage parents to register their child's seat through the manufacturer or online.
Children between 5 years and 8 years of age who weigh more than 40 pounds are too big for toddler seats but not yet large enough to fit the seat belts designed for adult passengers. The lap belt, designed to fit across the strong pelvic bones in an adult, slips up to ride across the mid-abdomen of a child. In the event of a crash, the belt applies maximum force to the unprotected abdominal contents along with excessive forward flexion, resulting in a serious "seat belt injury," such as a duodenal wall hematoma, transected pancreas, or fracture of the posterior elements of the lumbar spine with transection of the spinal cord.17 In addition, children who are graduated prematurely to a built-in seat belt are at risk of "submarining" (sliding out of the lap belt) and neck injury caused by improper fit of the shoulder belt. Moreover, poor fit makes the shoulder belt uncomfortable, so the child puts it under the arm or behind the back, increasing the risk of injury in a crash.
Many devices are marketed to improve the fit of the adult-sized seat belt for children. They usually attach to the seat belt and all do the same thing: pull down the shoulder harness for comfort at the expense of pulling up the lap belt, dangerously, over the abdomen. The devices have not been crash tested, and they decrease the integrity of the safety system. They should never be recommended to parents.8
The best solution in this age group is a booster seat, which simply raises the child a few inches, improving the fit and comfort of the seat belt. Recent research suggests that booster seats lower the risk of serious injury by 59% compared with seat belts alone.2 Because booster seats do not have to be secured directly to the seat of the vehicle, they are easy to use. Although all of the booster seats on the market meet Federal Motor Vehicle Safety Standards, the AAP recommends the high-back booster because it provides some head support (Figure 4).8 Low-back and no-back boosters do not offer head or neck protection. Booster seats should always be used with a lap and shoulder belt rather than the lap belt alone.
Beginning when a child weighs 40 pounds and outgrows the forward-facing toddler seat, a booster seat should be used until the child reaches 4 feet, 9 inches in height and 80 pounds in weight and can sit with the lap belt low and flat across the thighs and the shoulder belt across the chest (over the midclavicle and center of the chest). The child's bottom must rest against the seat back, and the knees must be comfortably bent over the edge of the seat.
Only seven states mandate the use of booster seats for children.18 Allowing for the fact that booster seat use is hard to observe because low-back boosters are not visible from outside the vehicle, the NOPUS study found that only 6% of children 4 to 7 years of age were using the recommended high-back booster, only 83% were restrained at all, and 29% were riding in the front seat. For all children from birth to 7 years, the child was much more likely to be restrained if the driver was wearing a seat belt.10
For children of any age, riding in the back seat is safer than riding in the front and is associated with a 30% reduction in fatal injury46% if the car is equipped with front airbags because of the additional danger airbags pose to children in the front seat.19 This effect holds true even in side-impact crashes.20 For this reason, the NHTSA recommends that all children under 12 years ride in the rear seat.21 This does not always occur, however. Of the 233 9- to 11-year-olds who were killed in a car crash in 2001, 80 (34.3%) were riding in the front seat, and fewer than half were wearing a seat belt properly.22
Standard seat belts reduce the risk of serious or fatal injury by at least 50% in children over 9 years of age. Seat belt use declines, however, as children grow older. In a recent study, fewer than 40% of 7- to 12-year-olds riding in the rear seat were wearing a seat belt. School-age children are more likely to use a seat belt if the driver is belted; in the same study, only 16% of school-age children were belted when the driver was unbelted.23
Many new health and safety issues arise as children enter adolescence. Teenagers' willingness to take risks puts them in danger of early pregnancy, sexually transmitted diseases, tobacco addiction, and drug and alcohol problems. But each of these risks directly affects a relatively small percentage of the total teenage population. On the other hand, more than 80% of the US population has learned to drive by 20 years of age.
A driver's license is a badge of independence awarded on the road to adulthoodone greatly anticipated by most teenagers. The novice driver, however, poses a serious health threat to himself or herself and others on the road. With a driver's license, the teenager's activities suddenly change24 and so does the risk of significant injuryas well as the risk of directly causing injury to someone else. The crash rate for teenage drivers is as high as six times that of older drivers and, in crashes involving a teenager, the adolescent driver is at fault more than 80% of the time.25 Although teenagers account for about 7% of licensed drivers in the US, they are involved in 15% of fatal crashes.26 Sixteen-year-old drivers are particularly at risk,27 and are most likely to be the driver at fault.28 Of 795 16-year-olds killed in car crashes in 2001, 436 (54.8%) were driving, and only 181 (41.5%) of the drivers were wearing a seat belt.29
The high crash risk for teenagers results from a combination of immaturity and inexperience. Immaturity is age related and associated with decreased perception of risk, increased willingness to attempt behaviors identified as risky, and greater suggestibility by peers. Inexperience is skills based and associated with less ability than experienced drivers to perceive specific road situations accurately and with poor estimation of safe turning speeds, traffic gaps, and stopping distances.
Because of the high crash rate for teenage drivers, 37 states and the District of Columbia have enacted special procedures for licensing teens: graduated programs to protect novice drivers from high-risk situations while they are learning.30 In these states, the teenager first must pass a written test to obtain a learner's permit, hold the learner's permit for a mandatory period, then pass a driving test to obtain a junior license. The junior license has specific limitations designed to reduce exposure to risk, including restrictions on nighttime driving and the number of passengers. Finally, the teenager obtains a regular license if he or she remains crash free and conviction free for a specified time.
Graduated driver licensing programs decrease the crash rate of novice teenage drivers,31,32 but parents in every state, whether or not it has a graduated licensing law, can and should insist on safety for their teenagers who are learning to driveor riding in a vehicle with a novice driver. The first point to emphasize is the necessity of always wearing a seat belt. Teenage passengers riding with an adult driver are belted less often than the driver, but teenagers riding with a teenage driver are belted less than 50% of the time.33 Only 83 (22.5%) of the 359 16-year-old passengers who were fatally injured in 2001 were wearing a seat belt.1
Whether or not the state has legislated limits on teenage driving, simple steps, enforced by parents, can help keep novice drivers from crashing. Parents can ensure that novice drivers learn appropriate skills by requiring that they complete a specified number of hours of supervised driving before they take the road test. Some of that time spent in supervised driving should be at night or in bad weather.
For many parents, having a teenage driver in the family means welcome help with chauffeuring younger siblings. Teenagers who drive with younger children must be educated about child passenger safety and the need to use appropriate restraints consistently for young passengers.
Teenagers are especially at risk of serious crashes at night, beginning at about 9 p.m. Once they are allowed to drive unsupervised, a nighttime driving restriction can help protect them for the first year.31,32,34 This is easily enforced by parents, who control access to car keys.
For novice teenage drivers, transporting passengers significantly increases the risk of a serious or fatal crash. The increase is greatest for the youngest drivers35 and appears to grow further when the passengers are teenagers36 and when three or more passengers are riding in the vehicle.37 As a result, the National Transportation Safety Board now recommends that "young, novice drivers with a provisional [intermediate/junior] license [be restricted] . . . from carrying more than one passenger under the age of 20 . . . for at least six months."38 This restriction is clearly enforceable by parents, who can not only limit the number of passengers their teenager can carry but also can forbid their child to ride with a novice teen driver.
The pediatrician's role in preventing motor-vehicle-related injuries to teenagers is to emphasize that their burgeoning independence requires an adult approach to their own health and well-being. This means wearing a seat belt, whether they are driving or riding. It means accepting that with increased freedoms comes increased responsibilitysuch as for the safety of passengers. And it means never driving under the influence of alcohol. A brief discussion with the parent(s) and the teen can help both understand the seriousness of their new roles.
Pediatricians have an important role in preventing serious or fatal injuries to children. The first step is understanding the magnitude of the risk. Because riding in a motor vehicle is the most dangerous thing children do, accurate, straightforward, and timely advice, including who needs to be restrained (everybody), which children should face the rear of the vehicle, when it's safe to move up to a booster seat, who should ride in the front seat, and how to help keep teenagers safe on the road, could be lifesaving.
