Despite the reported magnitude of road traffic injuries,1 various sources suggest official figures may underestimate the number of deaths by more than 30%.2 As of January 2009, 27 million vehicles were registered in Viet Nam of which 95% are motorized two-wheelers, a figure that increased by an average 7680 new motorcycles each day in 2008.1

The effectiveness of motorcycle helmets in preventing head injuries are well documented.3 Successful examples include China (Province of Taiwan)4 and Thailand5 where reductions in head injuries of 33% and 41% respectively were reported after the introduction and enforcement of mandatory helmet laws.

History of helmet legislation

Despite the long history of motorcycle helmet laws in Viet Nam, low penalties and limited enforcement coverage made them largely ineffective, resulting in approximately 30% compliance.6 A brief history of helmet legislation in Viet Nam is described in Table 1.

Collaborative advocacy from many sectors came to fruition on 29 June 2007 when the Prime Minister, Nguyen Tan Dung passed into law a strategy that represented a dramatic strengthening of helmet wearing requirements. Coming into effect on 15 December 2007, Viet Nam's new helmet law required ALL riders and passengers to wear helmets on ALL roads without exceptions.7


Shortly after the introduction of the legislation, several loopholes that had the potential to reduce its effectiveness were identified. Most loopholes have subsequently been resolved or are in the process of being closed.

First, the legislation omitted reference that required helmets to be correctly and securely fastened. Traffic police did not have powers to enforce unfastened helmets until November 2008 when riders and passengers with an unfastened helmet were penalized as if no helmet was worn.8

While the new law required helmet wearing for all riders and passengers, existing legislation prevented children under 16 years from being fined.9 Further, legislation did not make adults carrying children financially responsible when the children didn’t wear helmets, effectively preventing enforcement of helmet wearing in children. The impact of this was seen in roadside surveys showing helmet wearing averaging 39% in children compared to more than 97% in adults. There are also ongoing challenges over widespread but unfounded beliefs that the weight of helmets increased children's risk of neck injury.10 Draft legislative revisions have introduced a mechanism that will make adults financially liable when a child passenger under 16 does not wear a helmet.

Availability and quality of helmets

Past attempts at effective helmet legislation were hampered by quality standards that only included heavy, full-face helmets that the Vietnamese semi-affectionately called “rice cookers”. In 2001, the standards were revised to make provisions for a tropical helmet that provided both a high degree of impact protection but was also lighter and more suitable to the tropical climate in Viet Nam.

While revised standards provided a well needed boost to the public acceptability of helmets, the quality of helmets has the potential to limit the effectiveness of legislation. A survey in April 2008 by the Viet Nam Standard and Consumer Association found that up to 80% of motorcycle helmets on the market did not meet national standards.11 In November 2008, the Ministry of Science and Technology introduced revised standards (QCVN2) that strengthened quality assurance requirements to limit market infiltration of substandard products.

Enforcement of legislation

The new law substantially increased penalties for non-wearing from 20 000–40 000 Viet Nam Dong (VND) (approximately US$ 1–2) under the 2007 legislation to 100 000–200 000 VND (US$ 6–12) per offence,12 which represents more than 30% of the average monthly income per capita.13 Data from the traffic police indicate that in 2008 more than 680 000 infringements were issued against riders and passengers for not wearing a helmet. Revenue from road traffic infringements are collected by the State Treasury. Some of these funds go towards strengthening road safety; however these are not specifically earmarked for this purpose alone.

Intersectoral collaboration

In 1997, Viet Nam established a multidisciplinary council comprising representatives from 15 ministries and agencies including transport, police, health and education to lead the development and implementation of all national road safety programmes.14 This National Traffic Safety Committee (NTSC) is hosted and chaired by the Minister of Transport and is duplicated in each of Viet Nam's 63 provinces.

The national helmet law was developed and implemented by the NTSC on behalf of the Vietnamese Government. The NTSC work included obtaining the clearance on the details of the helmet law, collaborating and consulting with provincial networks to ensure nationwide implementation and for reporting on implementation progress and any barriers to the Prime Minister.

Specifically, individual members of the NTSC contributed to important processes, including the Ministry of Transport (drafting the legislation), the Ministry of Public Security (enforcement), the Ministry of Health (hospital surveillance), the Ministry of Education and Training (school based safety programmes) and the Ministry of Culture and Information (social marketing). The successful implementation of the law is a tribute to the intersectoral collaboration of the NTSC around this defined national objective.

The NTSC has also established partnerships with bilateral and multilateral agencies, nongovernmental organizations and private companies to streamline international assistance towards achieving national road safety objectives. One such partnership with social advocacy group, the Asia Injury Prevention Foundation, has produced three national mass-media campaigns since 2005 and distributed 350 000 free helmets to school-age children nationwide.

Impact of the helmet law

While no national surveys have been completed either before or since the introduction of the helmet legislation, time-series observations from a random selection of the road network in three of Viet Nam's 63 provinces (Yen Bai, Da Nang and Binh Duong) found significant increases in helmet wearing in both riders and passengers. In Da Nang, wearing in riders increased from 27% (November 2007) to 99% (June 2008) and 21% to 99% in passengers (Fig. 1).

Differences in the enforcement of pre-2007 legislation resulted in variations between provinces in baseline wearing rates. For example, a pilot programme in Yen Bai mandated helmet wearing in 2003, hence the higher baseline in November 2007 compared to Da Nang and Binh Duong. With regards to injury outcomes, findings from a Ministry of Health study in 20 central and provincial hospitals (out of 100 nationwide), capturing a total of 49 782 road-traffic injured patients between September 2007 and March 2008, indicated the risk of head injuries decreased 16% and the risk of death by 18% after the first three months of the law’s introduction. Both of these figures are statistically significant.15

By December 2008, one year after the legislation took effect, national police data reported 1557 lives saved and 2495 serious injuries prevented compared to the same time in 2007.

Given the predominance of motorcyclists, the law will make a substantial contribution to a reduction in total road-traffic deaths. While there are limitations in available information and therefore the strength of the causal link between the introduction of the legislation and the injury reductions, the outcomes are consistent with the known effectiveness of helmets and enforced helmet legislation.35


This review has highlighted some key contributors to the effectiveness of the 2008 helmet legislation. The well documented history of effective helmet programmes from many countries could have contributed to instilling confidence in the Government that similar legislation could also be successful in Viet Nam, despite unsuccessful attempts in the past.

This legislation was implemented in a manner that research has shown to be effective: (i) strict penalties were set for not wearing helmets, ten times higher than previous levels; (ii) advanced public education and social marketing ensured the population was aware of the legal obligations and high penalties; (iii) the Government used the civil service as role models, requiring that all government employees (approximately 4 million citizens, plus members of the armed forces) wear helmets three months before the law came into effect; (iv) enforcement was stringent from the date the law became effective; (v) legislation covered riders and passengers on all roads, reducing the potential for any confusion regarding the obligation to wear a helmet; and (vi) affordable, high-quality, climatically appropriate helmets were readily available to the population.

Legislation was issued by the Prime Minister, ensuring the highest level political commitment. National leaders also supported public education efforts in the lead up to 15 December, including the distribution of 50 000 helmets to low-income families nationwide.


The implementation of the motorcycle helmet legislation has been an important milestone in road safety in Viet Nam. The experiences and lessons learnt through this implementation should serve as an important example of multisectoral collaboration to other developing countries with a high burden of road traffic injuries and a predominance of motorized two-wheeler transport (Box 1).

Box 1. Summary of main lessons learnt

This review has highlighted key contributions to the successful implementation of helmet legislation in Viet Nam:

  • The highest level of political support;
  • Unequivocal legislation requiring all riders and passengers to wear helmets on all roads at all times; and
  • Stringent and consistent enforcement and substantial increases in fines applied to offenders.
