SpeciafeatureMotor vehicle accidents with child passengers ~ Is your child well-protected from danger? ~1 Introduction
Child casualties in traffic accidents by means of transport for the year 2014 recorded respective highs at
71% for pre-school children (under six years of age) while occupying vehicles, 36% for elementary
school lower grade children while walking and 62% for junior high school children while riding bicycles(see figure on cover page). Further, accident detail of pre-school children occupying vehicles reveals thatmany of them had not used child seats at all, while many others had used the child seats wrongly,
resulting in casualties. It can be said that this is mainly the responsibility of the adults who are theirguardians. Therefore in this issue we shall analyze whether these guardians had protected theirpre-school children who are occupying the vehicle well from danger.

ITARDA INFORMATION no.106■Who was driving the vehicle when the preschoolers suffered casualties?
Fig. 3 shows the breakdown of age and gender of drivers whom the preschoolers were riding together
with, when the latter suffered casualties. Apparently, young women aged 25 to 39 accounted for the
majority of such drivers. Further, men drivers of the same age group were also high in number. Many ofthese men and women drivers are assumed to be the parent of the preschoolers. Defining these drivers
aged 25 to 39 as the “parent generation,” let us now look into the details of such preschooler casualties,
when the former was driving the vehicle.

Fig.1 shows the number of casualties of preschool children (hereafter “preschoolers”) while occupying
motor vehicles and the casualty ratio by means of transport. Whereas the number of casualties ofpreschoolers while occupying motor vehicles has declined since 2003, the casualty ratio is on the rise
every year and in 2012 it has reached 71%.

■Why do preschooler casualties occur more often when the parent generation is driving?
It may be because the chances of the parent generation riding the preschoolers are high. There wecompared the situation of parent generation involved in accidents with all age group. Fig. 4 shows theratio of passengers (including the uninjured) when the accident occurred by the age group and gender ofthe drivers, while Fig.5 shows the ratio of the preschooler passengers in accidents who sufferedcasualties. As Fig.4 indicates, ratio of young women drivers of age group 25-39 riding with passengers ishigh, and as Fig.5 indicates, the ratio of preschooler passengers suffering casualties is also high; one of
the reasons for more preschooler passengers suffering casualties may be due to the fact that the
chances of young women drivers riding with preschoolers are high. However, no marked trend could beseen with the men drivers of the age group of 25-39 who seem to belong to the parent generation likethose of the women drivers.

As an indicator for determining “whether the driver was driving safely,” let us look at the fatal and serious
injury ratio (%) of drivers. As is evident from the formula, this points at the fact that the driver either diedor sustained serious injuries rather than getting away with minor injuries in the accident, and lower thevalue, the more the driver proves to be dedicated to safe driving. Accordingly, Fig.6 shows the fatal andserious injury ratio of drivers by the age group and gender of the driver by the presence or absence ofpassengers (including the uninjured). On the other hand, Fig.7 shows the fatal and serious injury ratio ofdrivers when the preschooler passengers riding with them also suffered casualties. As Fig.6 indicates,
the fatal and serious injury ratio is low when a passenger is present suggesting that the driver was
driving safely. Moreover, Fig.7 which considers only the passengers in question who suffered casualties
shows that the fatal and serious injury ratio is further low when the passengers riding along arepreschoolers. Now, the reason why the fatal and serious injury ratio for the men and women of age
group of 25-39 is on the whole lower than that of the all age group, may be mainly because of the factthat younger male and female adults are more tolerant to shock in accidents.

It is mandatory to fasten your seat belt while riding a vehicle, irrespective of your age. Nevertheless, as it
is difficult for a child with relatively short stature to fasten the seat belt properly, the use of a child seat isrecommended. Further, it is required by the law that children under the age of six must be seated on achild seat when riding a vehicle. Let us now see how many of the adults are properly using child seats
for the children under the age of six.
■How safe is a child seat?
Fig. 8 indicates the fatal and serious injury ratio of children under six who suffered casualties in
accidents by the usage situation of child seats. It is known that the fatal and serious injury ratio can be
reduced to one-fourth when the child seat is used properly than when it is not used. However, it isimportant to use the child seat properly; otherwise the aforesaid reduction cannot be achieved at all.
Therefore it is essential to use the child seat properly to reap its safety benefits.

You may have now understood how effective child seats are in protecting the child from danger, but how
many drivers use child seats properly. Fig.9 shows the situation of drivers wearing seat belts themselves,
when the children under six were riding along. Apparently, the ratio is very high with 97.3% of the drivers
wearing seat belts. Whereas Fig.10 shows the ratio of children under six (casualties only) using childseats when riding together at that time. Drivers who had used child seats were lesser at a ratio of 66%,
as compared to fastening their seat belts themselves, whereas the ratio of using child seats properly
were further less at a ratio of 58%. Moreover, as opposed to the requirement of using child seats forchildren under six, 11% of the adults used seat belts instead of child seats, suggesting that there aremany adults with low awareness about protecting their children from potential danger. Fig.11 shows theratio of child seat usage for children under six (casualties only) based on the ratio of drivers whothemselves did not fasten their seat belts (2.2% of the total). The ratio of using child seats when thedrivers did not fasten their own seat belts was at 42%, less than half of the total and the ratio of using
child seats correctly was much lower at only 26%. This indicates that the drivers who did not fasten theirown seat belts had a very poor usage ratio of child seats, as compared to the drivers who had fastened
their own seat belts. Therefore, many of the adults who are not conscious about their own safety must
admit that they are not properly protecting their children who are riding along with them.

Fig.11 shows theratio of child seat usage for children under six (casualties only) based on the ratio of drivers whothemselves did not fasten their seat belts (2.2% of the total). The ratio of using child seats when thedrivers did not fasten their own seat belts was at 42%, less than half of the total and the ratio of using
child seats correctly was much lower at only 26%. This indicates that the drivers who did not fasten theirown seat belts had a very poor usage ratio of child seats, as compared to the drivers who had fastened
their own seat belts. Therefore, many of the adults who are not conscious about their own safety must
admit that they are not properly protecting their children who are riding along with them.

■In what situations are the child seats not used?
There are various reasons for riding children on vehicles and as such the usage of child seats is
expected to vary according to that very reason. Let us target the young women drivers’ age group of
25-39 years where the casualties of children under six were high and study the situation of child seatusage by day of the week and the purpose of travel. Fig. 12 shows the child seat usage ratio for children
under six (casualties only) by day of the week. Difference is apparent between weekdays (Monday to
Friday) and weekend (Saturday and Sunday) with the usage ratio lower for weekends. Fig. 13 shows the
purpose of travel of children under six (casualties only) by weekdays and weekends. Apparently, themajor purposes of travel in both cases were “shopping”, “visiting” and for “pick-up”. Further, the graph byday of the week shows that “shopping” and “visiting” were done more during weekends whereas“pick-ups” have been reduced to less than half.

Fig.14 shows the child seat usage ratio for children under six who suffered casualties, by purpose of
travel and by weekday and weekend. The usage ratio for weekends is low for all other purposes except“visiting hometown.” For purposes that are repeated daily on routine basis such as picking up one’s childfrom the kindergarten, child seat usage has become a habit of many of the drivers. However, during
weekends due to reasons such as the same routine work seeming a little different during weekends andfeeling a bit relaxed during weekends, the usage ratio appears to be low. Also the reason may be thatmany drivers who are not usually used to riding children along and those who do not drive with them
regularly take to the road during weekends.

Next, let us study the situation of child seat usage by the grandparent generation, who other than theparent generation ride the children in vehicles more often. Here, grandparent generation refers to men
and women of age 55 years or more having grandchildren under the age of six. Fig.15 shows the childseat usage ratio by generation of the drivers for children under six (casualties only). Apparently, in the
grandparent generation, the ratio of properly using child seats is very low at 38%, as compared to theparent generation. Therefore, it is very important to give a bit more heed to safety when riding along withyour treasured grandchildren you have been entrusted with. There may be instances when you are notcarrying the child seats as you do not ride with them too often. So ask for the child seat when you havebeen entrusted with the child and correctly fit them on to the vehicle with the help of the parents thereby
paying attention to the safety of the children.

The summary of points to be careful about when riding with children under six in generaland by generation is as follows:● General(1) Be sure to use child seats properly when riding children under six.

Fig. 16 shows the ratio of protective equipment (seat belt and child seat) usage by generation and by position
occupied in the vehicle for all the passengers who suffered casualties in accidents. The usage ratio of protective
equipment in the front seat is very high irrespective of generation, but low for rear seats. Particularly, the usage ratio
gears down with the increase in age up to the high schoolers but again gains momentum with adults. This may be
due to the fact that children who have not acquired a driving license are not well aware of the importance ofprotective equipment and hence the lower usage ratio. Therefore, it is the duty of adults to let the children familiarize
with protective equipment right from their childhood and thereby understand the importance of using them.
