More Vehicles Than Safe Roads: Road Traffic Injuries in Low- and Middle-Income Countries, How Globalization and Economics Shape Them and How Global Road Safety Initiatives Respond

The Burden

Road traffic injuries are one of the world's leading causes of death and the leading cause of death for children and young people aged 5 to 29. The World Health Organization put road crash deaths in 2021 at roughly 1.19 million worldwide, only slightly lower than in 2010, and that about 92% of these deaths occurred in low- and middle-income countries, even though those countries have a much smaller share of the world's vehicles than of its road deaths (World Health Organization, 2023). More than half of those killed are pedestrians, cyclists and riders of motorcycles and other two- and three-wheelers. Millions more are seriously injured each year, often young working adults whose disability pushes families into poverty. The sections that follow take up three questions in turn: what global integration has done to road safety, why some countries fare so much worse than others, and what the international response has accomplished.

How Globalization Drives the Problem

Globalization has put vehicles within reach of millions of people in countries whose roads, laws and emergency systems were built for far fewer. Global manufacturing and trade have made inexpensive motorcycles and scooters widely available across Asia and Africa, and used cars exported from high-income countries often lack modern safety features such as airbags and electronic stability control. Rapid urbanization, driven in part by global economic integration, has pushed pedestrians, cyclists, motorcycles, buses and trucks onto the same crowded roads, often without sidewalks, crossings or separated lanes.

Global supply chains also shape who travels and how. Delivery work for global platforms has put more young riders on motorcycles for long hours, and freight trucking along international trade corridors brings heavy vehicles through towns where children walk to school.

How Globalization Helps

Globalization also spreads the knowledge and tools to prevent crashes. Vehicle safety standards developed in one region can be adopted by others, and some countries now require imported used vehicles to meet minimum safety standards. International road assessment programs share methods for rating road safety and prioritizing upgrades. Research on what works, such as helmet and seat belt laws, travels quickly, and global funding partnerships support enforcement, data systems and emergency care in countries that could not fund them alone.

Economic and Environmental Factors

Income strongly shapes outcomes, but not in a simple straight line. Poorer countries typically have less money for safe road design, enforcement, vehicle standards and trauma care, and injured people may wait hours for treatment. Yet wealth alone does not guarantee safety. An analysis of countries in the Eastern Mediterranean region found that, in 2015, road traffic mortality rates were more than twice the global average in both low-income and high-income countries of the region, with motor vehicle occupants at especially high risk, and that severe injuries fell sharply in high- and middle-income countries while remaining high in low-income countries (Sengoelge et al., 2018). Rapid wealth without strong safety laws and enforcement can bring more and faster cars rather than fewer deaths.

The built environment is the other major factor. Roads designed for vehicle speed rather than all users, missing sidewalks and crossings, poor lighting and mixed traffic without separation all raise risk, especially for pedestrians and riders. Environmental conditions such as heavy rain, dust and unpaved roads add hazards where road maintenance is underfunded. Because the burden falls on those who walk and ride, the poor, who are least likely to own cars, bear a disproportionate share.

Simple, proven protections are often missing. For motorcyclists, helmets reduced the risk of death by an estimated 42% and head injury by 69% in higher-quality studies (Liu et al., 2008), yet helmet laws are absent, weak or unenforced in many countries, and helmets sold may not meet safety standards.

How Initiatives and Agencies Respond

The United Nations has declared a Second Decade of Action for Road Safety for 2021 to 2030, with a global goal of halving road traffic deaths and injuries by 2030, supported by a Global Plan that promotes a safe system approach: designing roads, vehicles, speeds and emergency response so that inevitable human errors do not become deaths. The World Health Organization coordinates the effort, publishes global status reports that track deaths and national laws, and promotes a technical package of proven measures covering speed management, leadership, infrastructure design, vehicle safety standards, enforcement of traffic laws and post-crash survival.

Other agencies fill specific roles. UN regional economic commissions promote vehicle and road standards and legal agreements. Development banks finance roads and increasingly require safety assessments as a condition of lending. Philanthropic partnerships fund enforcement, data and advocacy in selected cities and countries, and international road assessment programs help governments identify and fix the most dangerous road sections.

Progress is real but slow. The small decline in global deaths since 2010 falls far short of the halving target, and the countries with the fastest motorization often have the least capacity to adopt the full package of measures.

Implications for Public Health Practice

For public health professionals, road traffic injury is a reminder that the leading killers of young people are not always infectious or chronic diseases, and that prevention often lies outside the health sector, in transport ministries, police forces and urban planning offices. Effective practice therefore depends on partnership. Health agencies bring surveillance data that show who is dying and where, emergency and trauma care that determines whether the injured survive, and the credibility to argue that road design and speed limits are health measures. Data quality is itself a challenge: in many countries, police records undercount deaths compared with health records, so linking the two sources is an early step. Finally, equity must guide priorities. Measures that protect pedestrians, cyclists and motorcycle riders, such as safe crossings, lower urban speed limits and enforced helmet laws, protect the people least able to afford a car and most likely to be killed.

Conclusion

Road traffic injuries show globalization's double edge: the same trade and urban growth that brought affordable mobility to millions also brought deaths to roads unready for them, while global cooperation offers the knowledge and funding to reverse the trend. Economic and environmental conditions determine who bears the burden, with the poorest road users paying most. Meeting the global goal will require countries to adopt proven measures such as helmet laws, speed management and safer road design, and international partners to support the countries where motorization is growing fastest.
