Road traffic injuries
- About 1.24 million people die each year as a result of road traffic crashes.
- Road traffic injuries are the leading cause of death among young people, aged 15–29 years.
- 91% of the world's fatalities on the roads occur in low-income and middle-income countries, even though these countries have approximately half of the world's vehicles.
- Half of those dying on the world’s roads are “vulnerable road users”: pedestrians, cyclists and motorcyclists.
- Without action, road traffic crashes are predicted to result in the deaths of around 1.9 million people annually by 2020.
- Only 28 countries, representing 416 million people (7% of the world’s population), have adequate laws that address all five risk factors (speed, drink-driving, helmets, seat-belts and child restraints).
Every year the lives of almost 1.24 million people are cut short as a result of a road traffic crash. Between 20 to 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury.
Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. These losses arise from the cost of treatment (including rehabilitation and incident investigation) as well as reduced/lost productivity (e.g. in wages) for those killed or disabled by their injuries, and for family members who need to take time off work (or school) to care for the injured.
There are few global estimates of the costs of injury, but an estimate carried out in 2000 suggest that the economic cost of road traffic crashes was approximately US$ 518 billion. National estimates have illustrated that road traffic crashes cost countries between 1–3% of their gross national product, while the financial impact on individual families has been shown to result in increased financial borrowing and debt, and even a decline in food consumption.
Road traffic injuries have been neglected from the global health agenda for many years, despite being predictable and largely preventable. Evidence from many countries shows that dramatic successes in preventing road traffic crashes can be achieved through concerted efforts that involve, but are not limited to, the health sector.
Who is at risk?
More than 90% of deaths that result from road traffic injuries occur in low- and middle-income countries. Road traffic injury death rates are highest in the low- and middle-income countries of the African and Eastern Mediterranean regions. Even within high-income countries, people from lower socioeconomic backgrounds are more likely to be involved in a road traffic crashes than their more affluent counterparts.
Young adults aged between 15 and 44 years account for 59% of global road traffic deaths.
From a young age, males are more likely to be involved in road traffic crashes than females. More than three-quarters (77%) of all road traffic deaths occur among men. Among young drivers, young males under the age of 25 years are almost 3 times as likely to be killed in a car crash as young females.
Risk factors and what can be done to address them
Road traffic injuries can be prevented. Governments need to take action to address road safety in a holistic manner, that requires involvement from multiple sectors (transport, police, health, education) and that addresses the safety of roads, vehicles, and road users themselves.
Effective interventions include designing safer infrastructure and incorporating road safety features into land-use and transport planning; improving the safety features of vehicles; and improving post-crash care for victims of road crashes. Interventions that target road user behaviour are equally important, such as setting and enforcing laws relating to key risk factors, and raising public awareness about these. Below are some key risk factors.
An increase in average speed is directly related both to the likelihood of a crash occurring and to the severity of the consequences of the crash. Some other facts are below.
- Pedestrians have a greater chance of surviving a car crash at 30 km/h or below.
- 30 km/h speed zones can reduce the risk of a crash and are recommended in areas where vulnerable road users are common (e.g. residential areas, around schools).
- Apart from reducing road traffic injuries, lower average traffic speeds can have other positive effects on health outcomes (e.g. by reducing respiratory problems associated with car emissions).
Drinking and driving increases both the risk of a crash and the likelihood that death or serious injury will result.
- The risk of being involved in a crash increases significantly above a blood alcohol concentration (BAC) of 0.04 g/dl.
- Laws that establish BACs of 0.05g/dl or below are effective at reducing the number of alcohol-related crashes.
- Enforcing sobriety checkpoints and random breath testing can lead to reductions in alcohol-related crashes of about 20% and have shown to be very cost-effective.
- Wearing a motorcycle helmet correctly can reduce the risk of death by almost 40% and the risk of severe injury by over 70%.
- When motorcycle helmet laws are enforced effectively, helmet wearing rates can increase to over 90%.
- Requiring helmets to meet a recognized safety standards is important to ensure that helmets can effectively reduce the impact of a collision to the head in the event of a crash.
Seat-belts and child restraints
- Wearing a seat-belt reduces the risk of a fatality among front-seat passengers by 40–50% and of rear-seat passengers by between 25–75%.
- Mandatory seat-belt laws and their enforcement have been shown to be very effective at increasing seat-belt wearing rates.
- If correctly installed and used, child restraints reduce deaths among infants by approximately 70% and deaths among small children by between 54% and 80%.
There are many types of distractions that can lead to impaired driving, but recently there has been a marked increase around the world in the use of mobile phones by drivers that is becoming a growing concern for road safety. The distraction caused by mobile phones can impair driving performance in a number of ways, e.g. longer reaction times (notably braking reaction time, but also reaction to traffic signals), impaired ability to keep in the correct lane, and shorter following distances.
- Text messaging also results in considerably reduced driving performance, with young drivers at particular risk of the effects of distraction resulting from this use.
- Drivers using a mobile phone are approximately four times more likely to be involved in a crash than when a driver does not use a phone. Hands-free phones are not much safer than hand-held phone sets.
- While there is little concrete evidence yet on how to reduce mobile phone use while driving, governments need to be proactive. Actions that can be taken include adopting legislative measures, launching public awareness campaigns, and regularly collecting data on distracted driving to better understand the nature of this problem.
Coordinating the Decade of Action for Road Safety
In 2010 a United Nations General Assembly resolution proclaimed a Decade of Action for Road Safety (2011–2020). This Decade was launched in May 2011 in over 110 countries, with the aim of saving millions of lives by improving the safety of roads and vehicles; enhancing the behaviour of road users; and improving emergency services.
WHO, in collaboration with the United Nations regional commissions, is the secretariat for the Decade and plays a key role in guiding global efforts by continuing to advocate for road safety at the highest political levels; compiling and disseminating good practices in prevention; sharing information with the public on risks and how to reduce these risks; and drawing attention to the need for increased funding.
Monitoring progress through global status reports
WHO will provide one of the tools for evaluating the global impact of the Decade of Action for Road Safety through the development of Global status reports on road safety. The first Global status report on road safety, published in 2009, provided the first comprehensive assessment of the road safety situation globally, while the second report – which will serve as a baseline for the Decade of Action for Road Safety – was released on 14 March 2013.
Providing technical support to countries
WHO works across the spectrum in countries, from primary prevention work through to rehabilitation of those who have been involved in road traffic crashes. As such, WHO works in a multisectoral manner, in partnership with national stakeholders from a variety of sectors (e.g. health, police, transport, education) as well as with other parties involved in road traffic injury prevention, such as nongovernmental organizations and academics.
In 2010, WHO and five other consortium partners received funding from Bloomberg Philanthropies to further road safety in ten countries. The "Road Safety in 10 Countries (RS10) Project" supports the governments of Brazil, Cambodia, China, Egypt, India, Kenya, Mexico, the Russian Federation, Turkey and Viet Nam by focusing on selected key risks for road traffic crashes. Efforts are focused on strengthening legislation and enforcement, capacity development, and educating the public through social marketing campaigns.
WHO also supports road safety efforts in other ways - for example, in improving safety around schools in Malawi and Mozambique, and in helping improve emergency services in Kenya and India and improving data collection systems (both in the health and police sectors). Over the Decade, WHO will continue to support these and other national road safety initiatives leading to sustainable government programmes.
WHO also provides guidelines that highlight good practice in road traffic injury prevention, and then supports governments to implement the suggested programmes or policies. For example, a good practice manual on increasing motorcycle helmet use and reducing drink-driving has been implemented in a number of ASEAN countries, while a guide to improving pre- hospital care will be used in Kenya and India. Capacity within countries is developed through the implementation of these guides as well as through direct training in different areas of injury prevention (for example, through courses on injury surveillance and on improving trauma care services).
