From 2003, the Government has tried  
to improve traffic safety, therefore the  
number of accident and traumatic brain  
injury (TBI) and the rate of death reduced  
suddenly. However, from the end of 2008,  
even though accident number decreasing, a  
number of TBI and deaths due to road crash  
are jumping up. This paper aims to analyze  
the reason of heavy injuries, TBI and deaths  
happening increased. The specific surveys  
were taken to motorcyclists, helmet market,  
traffic safety agencies and hospital in Hanoi  
and Ho Chi Minh City. Statistic method,  
integrated comparison, observation, expert  
interview survey and brainstorming method  
have been used in this study to analyze  
the problem. Then road safety situation,  
helmet usage, regulation and enforcement  
were analyzed. Base on these, proposal to  
Keyword: road safety, traumatic brain  
injury (TBI), traffic accident, road crash.  
I. Fact on Road Traffic Safety in  
vietnam  
From 1993, road traffic accidents  
had been increasing and traffic safety  
was a big problem in Vietnam. The  
number of road accidents has been  
increasing at alarming rate up to 2002.  
From 2003, the Government had tried to  
keep enforcement then the number was  
slowing down suddenly. However, traffic  
safety still is the hot problem in Vietnam.  
Even though the number of accidents and  
injuries has been decreasing; the number  
of fatalities is increasing year by year.

Feature of the interviewees  
Most of road accidents were caused  
by motorcycle (70% among the total). It is  
revealed that severity of traffic accidents  
is the problem, especially for motorcycle  
transport mode, 50% among the traffic  
accidents were traumatic brain injury (TBI)  
and the rate of heavy injury and fatal was  
25%. From 2007, the Government forced  
people to wear helmet, then some positive  
signal appeared as a result, however, a small  
change could not convince the improvement  
trend of road traffic.  
The survey result shows that 56%  
of interviewees were female; most of  
intervieweesweretheyouth(65%ofthetotal  
were under 35 years old) and well educated  
(60% among the total were educated at the  
university (Appendix 2, Table B).  
Asking about their motorcycle, 89% of  
intervieweesownedtheirmotorcycle;mostof  
those were less than 100cc (76%) compared  
with 23% of them being larger than 100cc  
but less than 500cc. 87% of interviewees  
were drivers and many of them going alone  
(80%); 75% of interviewees were traveling  
to/fromwork(ortoschooling)(seeAppendix  
2, Figure A, B, C, D).  
For the short time, the number of TBI  
has been reduced 20% - 50% compared to  
that of before; and the rate of death due  
to road crash reduced to 15%. However,  
from the end of year 2008, the number of  
fatalities was increasing; the number of TBI  
was jumping up as before.  
Helmet usage of motorcycle drivers  
and passengers  
Almost all of the interviewees own  
their helmets (98%) due to the regulation  
from the Government to force people to wear  
helmet when driving on the road. 36% of the  
interviewees bought helmets in the helmet  
shop, while around 24% bought at street  
market, 18% bought from shopping centre,  
shown more detail in figure 4. The number  
of people who were given helmets or bought  
them through suggestion of f, c, a is smaller.  
II. helmet Usage of motorcycle  
drivers and passengers  
The survey is taken with totally 1038  
samples, 517 samples in Hanoi and 521  
samples in Ho Chi Minh City. Place of  
survey allocated at 15 districts, 9 districts in  
Ho Chi Minh City and 5 districts in Hanoi  
(detail shown in Appendix 1, Table A).

most important thing, and less significant  
factor is quality of the helmet.  
The place to buy helmet between  
Hanoi and Ho Chi Minh City of respondents  
is shown more details in Appendix 4, the  
Hanoi people prefer to buy helmets in  
street market (17%) while Ho Chi Minh  
city people like to buy helmets at helmet  
shop (25%).  
There was the relationship between  
the age of respondents and the price of  
helmets. Even the trend is that people  
getting older would buy helmets with  
higher price, however, the difference is  
not much (Appendix 4, Table H). Data  
also showed the trend of people getting  
older would use more standard helmets  
as a relationship between the age of  
respondents and their usage of standard  
helmets (Appendix 4, Table J).  
The price to buy helmet between  
Hanoi and Ho Chi Minh City of respondents  
is different. The Hanoi people prefer to buy  
helmets with the price between 10 – 20 US$  
(30%) while Ho Chi Minh city people prefer  
the lower price, between 5 – 10 US$ (21%)  
(see Appendix 4, Table F).  
Data also showed the relationship  
between sex of respondents and their usage  
of standard helmets: male use standard  
helmets a little bit more than female  
(Appendix 4, Table K).  
The factors that affect people to buy  
helmets between Hanoi and Ho Chi Minh  
City are also a little bit different. The  
Hanoi people prefer to buy them due to  
theirs color (23%), which is higher than  
that in Ho Chi Minh city (see Appendix  
4, Table G). Some people who could buy  
helmets at the price more than 20USD  
consider much all given reasons (color,  
style/look, quality, standard) while most of  
people who could buy helmets at the price  
from 5 – 20 USD consider the color as the  
III. helmet market  
The market survey was be conducted  
in the two biggest cities of Vietnam with  
totally 25 retail outlets including 58% in  
Hanoi and 42% in Ho Chi Minh City (Detail  
showed in Appendix 5). Helmet market in  
Vietnam is diversified; there were 42% and  
25% of helmets sold in the general shop or  
supermarket and helmet shop only.

IV. Survey on TrafficAccidents from  
hospital Side  
The interview survey was taken to  
doctors at the Choray Hospital (the hospital  
for physical injuries) and HCMC Traumatic  
and Reform Hospital to identify the problem  
of helmet usage and road traffic accidents in  
the two major cities of Vietnam. According  
to the survey, the number of traffic accidents  
in the hospital occupied ½ of total cases  
there. Among traffic accident cases, a half  
among the total were physical break injuries  
and a half were traumatic brain injuries in  
half which ½ of those were non-helmet  
using cases and the left ½ were non-standard  
helmet using or wear on the wrong ways.  
Traffic accidents and helmet usage  
Traumatic brain injury (TBI) occurs  
when an outside force traumatically injures  
the brain. TBI can be classified based on  
severity, mechanism (closed or penetrating  
head injury), or other features (e.g. occurring  
in a specific location or over a widespread  
area). TBI is a major cause of death and  
disability worldwide, especially in children  
and young adults. Causes include falls,  
vehicle accidents, and violence. For traffic  
accidents, prevention measures include  
use of technology to protect those who  
are in accidents, such as seat belts and or  
motorcycle helmets, as well as efforts to  
Helmet usage, TBI trend to reduce in  
the short time and increase after that  
After forcing people to wear helmet  
reduce the number of accidents, such as in 2007, for the short time, the number of  
TBI has been reduced 20% - 50% compared  
to that of before. In Choray Hospital, the

helmet wearing. However, from the end of  
year 2008 up to present, traffic accidents  
with TBI were jumped up as before. 50%  
among the traffic accidents were TBI.  
Then serious level also increased, during  
that time, the heavy disease and fatal rate  
due to TBI was 25%, reduced to 15%  
when the Government started to enforce  
people to wear helmet, and now the rate is  
increasing at 25%.  
The form, style and size of helmets  
also have problems. The half-head helmets  
that are using by many motorcyclist are  
appropriate to travel around the inner city  
withaslowspeech(around30km/h).Ifcrash  
occurred, they would not suffer heavy injury.  
Most of victims of TBI due to road crash  
are wearing half-head helmets when driving  
high speed in highway. The full face helmet  
should be the best choice for people driving  
motorcycle on the highway for their safety.  
The young people like fashion styles which  
look more beautiful and colorful, however,  
those are under standard and could not help  
people avoid TBI from crashing. Many non-  
standard ones with un-clear information  
about the name, origin, manufacture, date…  
are distributed widely in the market. Those  
helmets could bring many potential dangers  
for people using them.  
Non-standard helmet usage or by a  
wrong way  
Data from the interview survey show  
that, in many cases, motorcycle drivers  
wear non-standard helmet and or in wrong  
ways, then the accident would be heavy  
and the victim would be TBI. In case of  
using standard helmet, even the helmet was  
broken or failed, the victims avoid from  
TBI. The doctor said about the important  
of standard type of helmets, and the right  
way of usage.  
Motorcyclists wearing helmets in a  
wrong ways such as non fasten, loose fasten,  
helmet size bigger than the head… could be  
heavily injured from road crash.  
Data from the National Traffic  
Safety Committee shows almost 99% of  
motorcyclists in the inner cities has used  
helmets. However, in the suburban areas,  
people wear helmets to deal with traffic  
police, then most of them wear helmets in  
the wrong ways.  
Helmets for the kids  
Roadaccidentsofthekidsareincreased  
during the time. Not wearing helmets  
when the kids going with their parents is  
prevailing. Moreover, in some cases the kids  
wearing non-standard helmets and or in the  
wrong ways could have the same problem  
as analyzed earlier.  
In many cases, people who used  
fashion helmets or plastic brim helmets  
could have serious injured in head, eyes,  
scruff and neck when crash happening. For  
non-standard helmets, the sponge could not  
absorb and the cover could not dispose the  
press of crashing then heavy injury could  
be happened.  
Survey that was taken in Kid Hospital  
2 revealed that 60% of the kids coming to  
the hospital were related to TBI due to road  
crashes. From August 2008 to July 2009,  
there were 43 kids under 15 years old with  
TBI and 63% of them due to road crashes.  
Many fashion helmets which are  
under standard are selling in the market.  
Those helmets could not protect people  
when crashing, even causes serious injury  
for them. According to the data from

vI. Conclusion  
In this paper, five specific surveys  
were taken to reveal the problem. The first  
survey was taken to 1038 motorcycle users  
to identify the use of helmets including  
type, price, place to buy, people’s features  
and reason of using standard or non-  
standard helmets including five factors  
price, type, color and form, brand, quality.  
Therefore it was reaved that most of people  
use non-standard helmets even those have  
certification stamp. The second survey was  
takenatthehelmetmarketandthenrevealed  
that many helmets sold in the market were  
non-standard. The third survey toward  
5 hospitals in the two cities and revealed  
that the number of traffic accident into the  
hospital occupied ½ of total cases there.  
Among traffic accident cases, a half among  
the total were physical break injuries and a  
half were traumatic brain injuries in which  
½ of those were non-helmet using cases and  
the left ½ were non-standard helmets using  
or wearing on the wrong ways. Data show
