Viet Nam has a high burden of road traffic injuries. In 2007 there were 12 800 deaths, or 15 deaths per 100 000 population, according to official statistics.1 Other sources of data suggest that official figures may underestimate the actual number of deaths and injuries by more than 30% and 90%, respectively.2,3

As of August 2008, there were more than 26 million registered vehicles in Viet Nam, and 95% were motorized two-wheelers.4 There are almost 9000 new motorcycles on the road each day. An estimated 60% of all road traffic fatalities occur among motorcycle drivers and passengers.3

Motorcycle helmets are a highly effective road safety intervention that reduces the frequency and severity of head injuries resulting from traffic crashes. According to a recent Cochrane review, helmet use reduces the risk of motorcycle injuries by 69% and motorcycle fatalities by 42%.5

In 2001, wearing a helmet became mandatory in Viet Nam for all motorcycle drivers and passengers on specific roadways, including national highways and other assigned routes.68 Unfortunately, there was limited enforcement of this legislation, and hence its effectiveness was low. Under this law, helmet wearing was estimated at approximately 30% on average but fluctuated greatly by time of day and type of road.9 Since helmet laws were first introduced, many stakeholders have tried to raise awareness and lobby for a law that will cover all drivers and passengers on all types of roads.

On 29 June 2007, the Vietnamese Government released Resolution 32, a decree that made it mandatory in Viet Nam for all motorcycle drivers and passengers to wear a helmet on all roads from 15 December 2007.10 Although the new helmet law made no specific exemptions for children, it was not fully consistent with existing legislation, since under the articles of Viet Nam’s Ordinance for Administrative Sanctions, children aged < 14 years cannot be given sanctions, including penalties for not wearing a helmet.11 Children aged 14 to < 16 years can be given a warning, and financial penalties apply for children aged 16–18 years but at half the rates for adults. Importantly, current legislation12 does not provide for a road traffic infringement penalty against the adult responsible for the child, a measure that can be applied in countries such as Australia,13 Cambodia14 and Malaysia (Rajam Krishnan & Shaw Voon Wong, Universiti Putra Malaysia, personal communication, 2008). Due to these limitations, the use of a helmet in children is not enforced.

Challenges to the use of helmets exist not only in the area of legislation. Shortly after the helmet law was introduced, the media began to publish reports from local medical practitioners who questioned the use of helmets by children and to claim that simply wearing could cause injuries to the neck.15 While many expert stakeholders in Viet Nam disputed these statements for lack of supporting evidence and because they went against the results of wide-ranging research on the effectiveness of helmets,16,17 many parents grew afraid of making their children wear helmets.

High quality helmets are manufactured and available in Viet Nam for both adults and children. This research, conducted by the Asia Injury Prevention Foundation on behalf of the Viet Nam Helmet Wearing Coalition, confirms that limited use of helmets among children is a problem in the country and explores its contributing factors.


Roadside and random population surveys were conducted in four major cities in Viet Nam. Three teams of 10 trained students who worked on weekends in the month of April 2008 surveyed a total of 4189 respondents in four cities (953 in Hanoi, 904 in Ho Chi Minh City, 994 in Can Tho and 1338 in Da Nang). Surveyors attempted to interview 1000 random respondents with equal distribution between genders and three age groups – 18–24 years, 25–40 years, and ≥ 41 years – but surveys were accepted from anyone willing to complete them.

Questions included information on demographics, knowledge about correct use of helmets, and opinions on child helmet use. Approximately 44% of respondents had children (range: 36–54%). For purposes of the survey, age groups were defined as follows: infants, < 6 months; toddlers, ≥ 6 months but < 2 years; children, ≥ 2 but ≤ 14 years.

In each city, one urban and one suburban intersection were selected at random and observed by a team of six trained observers from 08:30 to 09:30, and from 20:00 to 21:00 on one weekday and one weekend day. Additionally, a random intersection within 100 yards of a school was observed on one weekday between 15:30 and 16:30. Suburban observations in Can Tho and Da Nang were recorded by video and subsequently analysed.

A total of 18 734 roadside observations were made in the above time periods (5920 in Hanoi, 5407 in HCMC, 3644 in Can Tho and 3763 in Da Nang). Observers estimated the age of children and noted the use of helmets among people in three age groups: ≤ 7, 8–14 and ≥ 15 years.

Cross tabulations were made to compare the survey responses given by parents and non-parents. χ² was calculated using Stata 9.2 (Statacorp LP, College Station, TX, United States of America). The significance level was set at 0.05.


Roadside observations

Adults and children differed substantially in their use of helmets. On average, the greatest use among adults was seen in was seen in Da Nang (99%), followed by Can Tho (98%), Ho Chi Minh City (94%) and Hanoi (90%).

The use of helmets among children ≤ 7 and 8–14 years of age was 34% and 23%, respectively, in Hanoi; 28% and 52%, respectively, in Ho Chi Minh City, and 53% and 54%, respectively, in Can Tho. In Da Nang, observations were made only for children who looked ≤ 14 years of age (30%) (Fig. 1).

Road user surveys

Respondents were questioned on their knowledge of the penalties applied under the helmet law. An average of 42% (range: 35–54%) indicated that penalties did apply to the motorcycle driver when children are not wearing helmets. A further 32% (range: 27–43%) did not know (Fig. 2).

Respondents were also asked if they believed helmets were safe for children of different ages. Affirmative responses increased with the child’s age and ranged from 21–40% for infants, 36–52% for toddlers and 77–85% for children.

When asked whether children should wear helmets, participants responded in a similar manner to the previous question. Their affirmative responses ranged from 13–23% for infants, 16–29% for toddlers and 53–67% for children (Table 1). Significant differences exist between survey locations.

Respondents who confirmed that their children should not wear helmets were asked to explain the main reason for their opinion, and the majority replied that helmets increased the risk of neck injury in children of all age groups (Fig. 3). A negative response was given most frequently for infants (67%) and decreased across the other age groups.

Parents’ perceptions were also compared to those of non-parents with regard to the use of helmets among children. Parents consistently displayed a less educated view than non-parents in connection with the use of helmets by children aged < 14 years. In Ho Chi Minh City, parents were 10% less likely to believe that children should wear helmets than non-parents (P < 0.05). The data substantiated perceptions regarding the use of helmets by toddlers. In Hanoi parents were 12% less likely to believe that toddlers should wear helmets than non-parents (P < 0.05), while in Can Tho parents and non-parents had similar perceptions surrounding the use of helmets in toddlers (P = 0.715).


The new helmet legislation in Viet Nam has resulted in a substantial increase in the use of helmets, but only among adults; the wearing of helmets among children has remained low. Substantial differences between adults and children in the wearing of helmets were observed in the study.

Importantly, the observed use of helmets in children did not reflect the attitudes and opinions expressed by parents during interviews. An average of 82% of the parents surveyed agreed that helmets were safe for children 2–14 years of age, and 61% agreed that children in this age bracket should wear them when travelling on a motorcycle. However, only an estimated 38% of children actually wore helmets, according to roadside observations. One of the limitations of self-reported feedback is the potential for socially desirable responses that do not reflect actual behaviour.

The fact that the majority of parents did not know if they were subject to penalty or believed that they were if their children were not wearing helmets suggests that their belief in the risk of neck injury overrode their fear of penalty and law enforcement in contributing to the low rate of helmet use among children. This highlights the importance of continuing efforts to dispel the myth of neck injuries in future campaigns. The effect of the myth on helmet use in children was further corroborated when parents and non-parents were compared. Parents were more likely than non-parents to believe that children and toddlers should not wear helmets.

Many international organizations, including the Asia Injury Prevention Foundation, the United Nations Children’s Fund (UNICEF) and WHO, are currently supporting the Government of Viet Nam in its efforts to promote the use of helmets among children through various mechanisms, including advocacy, social marketing and support for capacity-building to enhance road safety.

As part of a collaborative approach, a legislative working group has been formed with representatives from various agencies of the Government of Viet Nam, with the support of WHO. The particular objective of this group is to introduce a legislative mechanism that will allow penalties to be applied to any parent or adult carrying a child on a motorcycle without a helmet.

The widespread circulation of the myth that wearing a helmet carries a risk of neck injury and the acceptance of this myth by many parents points to the fact that stakeholders were unable to effectively counter these rumours. WHO, the Asia Injury Prevention Foundation and UNICEF have subsequently increased advocacy for child helmet use through the media and through training workshops for senior officials and national legislators.18,19 The most recent campaign of the Viet Nam Helmet Wearing Coalition has focused on the importance of having children wear helmets.

The current study is limited by the lack of hospital data on fatalities and head injuries in children. Hospital data, disaggregated by age, has only been available since May 2008, so the early impact of the helmet law on helmet use among children cannot yet be assessed. As data from studies become available, they will provide a powerful advocacy tool in support of legislative changes surrounding child helmet use. Such data are strongly anticipated to dispel the unfounded myth of the risk of neck injury in children who wear helmets.


Despite some remaining challenges, the implementation of the mandatory helmet law has been a milestone in Viet Nam’s history of road safety policy. Many lessons can be learned from the experiences to date, not only for closing legal loopholes still present in Viet Nam, but also for regional low- and middle-income countries where motorcycles represent a frequent mode of transport for both adults and children.

The implementation of Viet Nam’s helmet law should be further evaluated over time and its effectiveness, particularly for children, assessed on an ongoing basis as loopholes are gradually closed. ■
