New global and country-level estimates suggest that routinely wearing helmets and seat belts, obeying speed limits, and avoiding driving drunk could save between 347,000 and 540,000 lives worldwide every year.
The benefits of more motorcyclists wearing helmets would be the biggest in China, where 13,703 lives could be saved every year, followed by Brazil (5,802 lives), and India (5,683 lives), says the study published in The Lancet.
Analysis of data from 74 studies in 185 countries estimates that targeting four key risk factors for road injuries and deaths (speeding, drink driving, and non-use of crash helmets and seat belts) could prevent between 25% and 40% of all fatal road injuries worldwide every year.
Interventions to reduce speeding such as infrastructure changes and electronic speed control could save an estimated 347,258 lives globally each year, while measures to tackle drunk driving such as enhanced drink driving enforcement could save a further 16,304 lives, the study says.
An estimated 121,083 and 51,698 lives could be saved by passing and enforcing rules on wearing seat belts and motorcycle helmets respectively.
Improving seat belt use would have a particularly large effect on reducing road deaths in the United States (saving an estimated 14,121 lives every year) and China (13,228). Tackling speeding would be the single most effective measure to reduce road fatalities in most countries, preventing an estimated 88,374 deaths in China, 1,027 in Spain, and 815 in the United Kingdom.
