The rapid growth of motorization in emerging and developing economies brings new opportunities—but also rising health and economic risks. Safe and Clean Vehicles for Healthier and More Productive Societies presents compelling evidence that poor-quality vehicles are a major contributor to road traffic deaths, long-term disability, and air pollution.
The report emphasizes that electrification alone is not enough. Instead, countries must adopt comprehensive motorization management policies, including regulating used vehicle imports, enforcing modern safety and emissions standards, and retiring unsafe vehicles.
These strategies can significantly reduce fatalities and serious injuries, protect human capital, and promote cleaner, more resilient transport systems.

The burden of road traffic injuries is a significant global challenge requiring urgent attention and investment. By integrating road safety investments with broader development goals and leveraging innovative financing solutions such as labeled sustainable bonds and loans, available financing for road safety projects can be dramatically increased.
The societal, economic, and human benefits of improving road safety are extensive, making it a critical priority for national agendas. Through strategic investments in road safety, economic burdens can be mitigated, long-term growth promoted, and a safer, more equitable world created for all.
The multilateral development banks -- together with the Global Road Safety Facility and with strong donor support -- can help countries catalyze the sustainable finance market to fund high-impact and results-oriented road safety projects.

Speed is one of the main road safety risk factors and is universally recognized as the leading contributor to road fatalities and serious injuries. But there is good news: the speed problem is solvable. Interventions that are proven to be effective exist, and it is well understood where and how they should be applied.
The newly published “Guide for Safe Speeds: Managing Traffic Speeds to Save Lives and Improve Livability” outlines interventions that work and provides guidance on how to select and implement speed limits that are safe for all road users. It also explains how barriers to changing traffic speeds—which are often based on lack of knowledge or misunderstandings—can be overcome.
A primary feature of the guide is its comprehensiveness. The guide covers all types of roads—from city streets to inter-urban roads and motorways (existing or new); all types of road users—from vulnerable road users such as pedestrians and cyclists to heavy motorized traffic; all types of speed limit changes—from national general speed limits to localized changes based on risk factors; all types of challenging constraints—from lack of resources to lack of data; and all types of countries—from low-income to high-income.

La velocidad es uno de los principales factores de riesgo para la seguridad vial y se reconoce universalmente como la principal causa de muertes y lesiones graves en carretera. Pero hay buenas noticias: el problema de la velocidad tiene solución. Existen intervenciones de eficacia comprobada, y se comprende bien dónde y cómo aplicarlas.
La recién publicada "Guía para Velocidades Seguras: Gestión de la Velocidad del Tráfico para Salvar Vidas y Mejorar la Habitabilidad" describe intervenciones eficaces y ofrece orientación sobre cómo seleccionar e implementar límites de velocidad seguros para todos los usuarios de la vía. También explica cómo superar las barreras para cambiar la velocidad del tráfico, que a menudo se basan en la falta de conocimiento o malentendidos.
Una característica principal de la guía es su exhaustividad. Abarca todo tipo de vías, desde calles urbanas hasta carreteras interurbanas y autopistas (existentes o nuevas); todo tipo de usuarios de la vía, desde usuarios vulnerables como peatones y ciclistas hasta tráfico motorizado denso; todo tipo de cambios en los límites de velocidad, desde los límites generales nacionales hasta los cambios localizados basados en factores de riesgo. todo tipo de limitaciones desafiantes, desde la falta de recursos hasta la falta de datos, y todo tipo de países, desde los de bajos ingresos hasta los de altos ingresos.

Low- and middle-income countries (LMICs) have been experiencing growth in vehicle travel and mobility but have not yet realized road safety gains experienced by high-income countries. Excessive and inappropriate speed is known to be a major cause of road crashes, injuries and deaths. Thus, speed management is considered a key initiative for improving road safety outcomes worldwide and has been applied successfully in most high-income countries.
Proven interventions do not necessarily have the same impacts in LMICs, or may not be feasible to apply, due significant differences in traffic mix, road user behavior, road design and vehicle standards.
This document summarizes current available knowledge about speed, its effects on safety, mobility and emissions, along with potential safety effectiveness of speed management initiatives in the LMIC context. Knowledge gaps for LMICs are clearly referenced for further consideration.
The knowledge summary provides a useful reference for practitioners wishing to inform themselves about traffic speeds, their selection and impacts on safety outcomes, mobility and emissions. The LMIC knowledge gaps will be useful in considering future research and data priorities.

The WHO, World Bank, FIA Foundation and Global Road Safety Partnership (GRSP) produced a series of good practice manuals, following the publication of the World report on road traffic injury prevention in 2004, which provide guidance on implementation of interventions to address specific risk factors in road safety. The topics covered in the initial series of manuals were: helmets (2006), drinking and driving (2007), speed management (2008), seat-belts and child restraints (2009), data systems (2010), pedestrian safety (2013), road safety legislation (2013), powered two- and three-wheeler safety (2017) and cyclist safety (2020).
Since the series of manuals was first published, the scientific evidence base relating to various risk factors and the effectiveness of interventions have continued expanding. Contemporary research has refined our knowledge about specific risk factors, such as distracted driving, and vehicle impact speed and risk of death for pedestrians. New issues and practices have arisen, such as a tropical helmet standard and an anti-braking control standard for motorcycles. New and existing interventions have been implemented and evaluated, with increasing application in LMICs. Research attention and policy response have also increasingly been applied to emerging road safety issues including e-bikes, drugs other than alcohol, fleet safety, urban mobility, micro mobility options, air and noise pollution, public transport and technological advances.
As a result of these developments, the good practice manuals required revision so that they can continue to be key references for road safety policy implementation and research. This is particularly important, given the emphasis placed on road safety within the framework of the 2030 Agenda for Sustainable Development and because of the global impetus to reduce road deaths and injuries, resulting from the declaration of the two United Nations’ Decades of Action for Road Safety (2011–2020 and 2021– 2030). The manuals have been revised to reflect these developments as they continue to be valuable resources providing evidence-based and cost-effective solutions to save lives and reduce injuries.
The management of speed remains one of the biggest challenges facing road safety practitioners around the world and calls for a concerted, long-term, multidisciplinary response. The speed at which a vehicle travels directly influences the risk of a crash as well as the severity of injuries sustained, and the likelihood of death resulting from that crash. This manual advocates for a strong and strategic approach to creating a Safe System, with speed management at its heart. Reducing motor vehicle speeds in areas where the road user mix includes a high volume of vulnerable road users, such as pedestrians and cyclists, and on non-divided rural roads, is especially important.

Across the developing world, countries are experiencing rapid growth in urbanization and motorization. While high motorization rates potentially meant hat more people will be able to claim the benefits of improved accessibility to goods and services as a consequence of enhanced mobility, there are questions about the sustainability of this future. Will countries be able to build and maintain infrastructure to accommodate increasing numbers of vehicles? Will the increasing number of vehicles and their characteristics support attainment of the Sustainable Development Goals (SDGs) Will they put in jeopardy countries’ ability to meet their climate commitments under their Nationally Determined Contributions (NDCs)? From a development impact standpoint, the nature of a country’s motor vehicle stock and how it grows affects three key and tangible outcomes.
First, the quality of the motor vehicle stock affects road safety outcomes—that is, the number of people killed or seriously injured in motor vehicle crashes. The characteristics of vehicles and their fitness or roadworthiness can affect fatality and serious injury outcomes. Second, the quality of the motor vehicle fleet affects air quality, particularly in cities. Motor vehicles are a key source of harmful air pollution, including carbon monoxide (CO), fine particulates (PM2.5), sulfur oxides (SOx), and ozone precursors (oxides of nitrogen and various hydrocarbons), and the amount of these pollutants they emit is directly related to how the vehicle was built and how well it is maintained. Finally, the profile of the vehicle fleet—what is the size and weight of vehicles in the fleet, how big are their engines, what kind of power control technology do they use, and how did their manufacturers engineer the technology of the vehicle to balance power with efficiency—affects the (fossil) fuel consumption of the vehicle stock as a whole, and, consequently, the greenhouse gas (GHG) emissions profile of the road transport sector.
This report presents the World Bank’s Motorization Management (MM) framework, which is intended to support client countries in the development of policies and measures aimed at managing vehicle stocks in a proactive, phased, and systematic manner to make them safer, cleaner, and more fuel efficient. The MM framework reflects a series of policy considerations and programs that can be implemented to improve the quality of fuels and vehicles in a country’s stock.

The Multilateral Development Banks (MDBs) Road Safety Working Group, established in 2009, is comprised of ten member institutions that are uniquely positioned to support countries in reaching their considerable and challenging road safety financing needs.
In early 2023, the working group reviewed progress made by the MDBs in financing road safety activities in low and middle-income countries (LMICs), and found that MDBs collectively committed $3.6 billion toward road safety initiatives in developing countries during the period 2018-2022. Three standalone road safety projects—in Bangladesh (World Bank), India (Asian Development Bank and World Bank), and Romania (European Investment Bank)—totaled $912 million in MDBs financing, which is more than one-quarter of the amount committed during this timeframe.
The review is based on details of road and urban mobility project financing provided by seven of the working group's ten members.

Road traffic injuries (RTIs) are well known to cause enormous human suffering in terms of both morbidity and mortality, and on a global scale. The economic dimension of the disease burden is far less well understood; but it is important to assess the size of the economic burden so that it can be considered when calculating the cost-benefit ratio of policies to tackle this problem. Because it is, in principle, and to some degree, an avoidable one.
This report focuses primarily on assessing various dimensions of the economic consequences of RTIs, as applied specifically to four Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan) – a part of the world in which there is still a major need to reduce RTIs.
This study shows that on top of the harm RTIs inflict upon human health, they also impose a considerable financial burden on health care systems. In 2016, the total estimated health costs of RTIs in these four countries was approximately Int$95 million, ranging from Int$2.8million in Tajikistan to Int$49.3 million in Kazakhstan. In Kazakhstan, the overall health costs resulting from RTIs were similar to the cumulative expenditure for rehabilitative and palliative care within the state-guaranteed basic package. The heavy financial burden on health care systems to manage RTIs in these countries adds weight to the urgency to increase preventive efforts by road safety policymakers, and should motivate appropriate organization of the post-crash response by health care system decision makers. The cost estimates discussed in this report indicate the potential for significant economic cost savings if both deaths and injuries from road crashes could be substantially reduced in these countries.

The World Bank estimates a significant funding gap in road safety of 260 billion to achieve SDG 3.6 and 11.2 in the next ten years, and recognizes that this gap cannot be closed through public funding alone and thus mobilization of private capital is required. The impacts of road traffic crashes reach far into the economy and can cost L/MICs as much as 6% of their GDP. The costs of a road traffic crash do not end at the roadside; they create ripple effects throughout the wider economy. Loss of income, property damage, insurance premiums, loss of taxes, and burdens on the health sector are just some of the far-reaching costs associated with road traffic crashes. Road traffic crashes can cost countries as much as 6 percent of their GDP and trap families in poverty as they lose income generating potential and focus on providing lifetime care.
This report examines the potential for private capital mobilization to close this gap. The report investigates the market failure to appropriately account for the cost of road crashes, which prevents private capital from flowing to road safety investments. The growth of socially responsible investing and the sustainable finance market offers a new opportunity to address this market failure. The report proposes different business models and financing instruments to channel private investment into road safety projects. These investment structures consist of subnational, public-private partnerships (PPPs) and corporate investments that can leverage the growing sustainable finance market, including social and sustainability-linked financings (SLFs).
The report also develops indicators that can be used to tie the cost of financing to the attainment of road safety targets, incentivizing borrowers to commit to road safety as part of SLFs. The report examines the enabling environment for structuring investable road safety projects in a sample of countries, looking at the barriers and opportunities, and proposing risks and mitigation strategies, like blended finance mechanisms and stable revenue sources, for long-term sustainability of road safety investments.
