Even as the world cut child deaths and AIDS deaths, about 1.19 million people died in road crashes each year, with more than 90% of fatalities occurring in low- and middle-income countries. The death toll has barely budged for two decades as cars spread faster
The numbers sit heavy because they don’t move.
Roughly 1.19 million people are killed by road crashes every year. according to estimates from the World Health Organization. and many times more—likely between 20 and 50 million—are injured. sometimes with life-altering disabilities. More than 90% of those deaths occur in low- and middle-income nations. even though those countries contain only around 60% of the world’s cars.
This is happening while other parts of global health move forward. This century, humanity has halved the mortality rate for children under five and reduced AIDS-related deaths from their peak by 70%. Road deaths, however, have remained roughly the same for the last 20 years. As the global car fleet doubled over the past 20 years, the burden shifted increasingly to lower-income countries.
“It kills about as many people as the world’s deadliest infectious disease — tuberculosis — and it is the leading cause of death globally for people in the prime of their lives. aged 5 to 29.” Those stakes help explain why road safety has begun drawing more attention. But they also underline the central cruelty: the threat is not purely natural. It’s a risk engineered into everyday life.
The late Dinesh Mohan of the Indian Institute of Technology put it bluntly in 2019. writing that it is “one of the few public health problems where society and decision makers still accept death and disability on such a large scale as inevitable.” In a separate exchange. James Leather. director of transport at the Asian Development Bank. said in 2024 conversation at the International Transport Forum summit that he felt “depressed” and wondered why “no one [was] taking this seriously.”.
What that means on the ground is stark. In the United States, road deaths account for around 1% of all deaths. Globally, that figure is about 2%. In a typical middle-income country like Vietnam, it is more than 3%. Even with fewer cars than wealthy countries have. poorer nations often face higher risk because people who can afford cars travel in private vehicles while everyone else walks. bikes. rides a motorcycle or scooter. or uses three-wheeled vehicles like an auto rickshaw.
Those outside automobiles are often referred to as “vulnerable road users,” and they share space with cars at high risk of being hit.
Cars themselves can be more dangerous in developing nations, too. Weaker safety standards and reliance on imported old cars mean some riders and passengers sometimes travel in vehicles that lack safety features long taken for granted in richer countries. including airbags and frames designed to absorb crash forces.
Then comes the pace of motorization. Cars and other motorized vehicles are spreading rapidly in the Global South—faster than the transition took place in North America and Europe—and doing so before governments have built safer roads. vehicle standards. adequate trauma care. or robust traffic regulations. Many countries lack comprehensive laws covering five behaviors that the WHO says shape road fatalities: high speeds. drunk driving. seatbelt use. helmet use for motorcyclists. and child restraints in cars.
In Southeast Asian countries. which have seen a massive proliferation of motorized vehicles since 2010. infrastructure can lag behind the scale of vehicles on the road. “Maybe the infrastructure was designed when you didn’t have so many cars. and now all of a sudden you have twice the number of cars that you did before. ” Nhan Tran. the WHO’s head of violence and injury prevention. said.
The consequences stretch beyond individual trauma into national budgets. Road crashes are described as a major burden on medical systems and as exacting economic costs, amounting to about 5% of national GDP in Vietnam, for example.
While the total number of global road fatalities has stayed roughly constant for decades. the gap between rich and poor countries has widened. Between 2010 and 2021. high-income countries. particularly in Europe. saw dramatic decreases in car crash deaths. while deaths in the vast majority of low-income nations—predominantly in sub-Saharan Africa—increased. Across lower-middle-income nations like India, the aggregate number of deaths and the per capita fatality rate stayed roughly flat.
In some places, enforcement changes the outcome. Leather pointed to helmets as an intervention that can make a big dent in deaths. In the Philippines. where he lives. national law requires that helmets be made available with every new motorcycle purchase. though the real test is whether people use them.
Kavi Bhalla. a professor at the University of Chicago’s department of public health sciences and an expert on global road safety. described what happens when enforcement differs. In an email. Bhalla said: “If you go to New Delhi today. nearly every motorcycle rider wears a certified full-faced helmet. This was achieved through strong enforcement.” He contrasted that with other cities in India. saying most do not enforce helmet law. have very low helmet use. and the result is many unnecessary deaths.
The argument emerging from that contrast runs deeper than personal behavior. Twenty years ago. two US economists published a highly influential paper on the relationship between a nation’s wealth and its traffic fatality rate. They argued that as countries get richer. motor vehicle ownership rises. and per capita car deaths rise too; then. as safer roads. vehicles. and traffic policies catch up. fatality rates start to fall—often described as a tipping point that comes at around $8. 600 in 1985 international dollars of per capita GDP.
But Bhalla said that framing can mislead. He described “economic determinism” as a way the problem becomes treated as inevitable until a nation becomes rich. Instead, he wrote that it is a mistake to think the shift has much to do with countries being rich.
Bhalla wrote that safety improved in Europe and the US once those countries established national road safety agencies. gave them authority to regulate what happens on the roads. and provided dedicated funding. Those agencies. Bhalla said. identified common traffic safety risks. investigated how best to address them. and then invested in large-scale interventions focused on safer designs of cars and roads. coordinated enforcement programs. and emergency medical systems. “Low and middle income countries can and should do this now,” he wrote.
The global effort has existed, but progress has fallen short. The United Nations aimed to halve global road deaths from a baseline of roughly 1.2 million by 2020. a goal that was not reached. Even so, holding the absolute number of traffic deaths constant has been described as meaningful given population growth. From 2010 to 2021, the global per capita road fatality rate decreased by about 16%.
Tran also said that in that same period. road safety has gained more visibility among political leaders and civil society as a badly neglected public health crisis. But after missing the 2020 target. the UN now aims to halve road deaths by 2030. and Bhalla told Leather he believed the world would “definitely not” meet that goal either.
One reason road safety remains difficult is that the problem doesn’t sit inside a single cause. Tran said it is “not the same as when you’re talking about Covid or HIV. where there is a virus” that you want to eradicate. He asked: “When you talk about road safety. what is the virus?” Is it dangerous individual behaviors—speeding. drunk driving. refusing to wear a seatbelt?. Is it deteriorating roads or a lack of sidewalks?. Or is it humanity’s growing dependence on cars themselves?.
Tran and other advocates call for focusing on upstream causes: the proliferation of cars and the built environment that often prioritizes movement of vehicles over movement of people. That approach emphasizes good urban planning designed to prioritize transit. walking. and cycling. so safety becomes “an inherent feature” of the transportation network rather than something patched on later.
The WHO director-general Tedros Adhanom Ghebreyesus echoed that message in the agency’s 2023 road safety report, writing: “As motor vehicles proliferate, countries are doubling down on transport systems built for cars, not people, and not with safety at their core.”
There is room for more than one kind of response. The American experience with car dependence is cited as an example of how a built system can lock in high road fatality rates. But even the critiques come with a specific caution: for many people in poorer nations. automobility offers freedom that rich countries once took for granted.
And simple interventions—ones that were instrumental in bringing down car fatalities in rich countries—should not be treated as mere Band-Aids. The approach. framed through both behavior and design. is to treat each death not as “a tragic act of God. ” but as the result of forces within human control.
In the end. what stays constant—what keeps happening every year—is the point that global health progress has not yet cracked road safety in the way it has cracked measles and smallpox. tuberculosis. AIDS. and many of the other killers people once saw as unavoidable. The tragedy is that the world still knows enough to change the outcome. and yet the road toll remains stubbornly. dangerously steady.
