How Britain Built Some of the World's Safest Roads

Britain's road death rate has declined 22-fold per mile driven since 1950, dropping from 111 deaths per billion miles to approximately 5 today, according to new analysis from Our World in Data. Annual road fatalities fell from 5,000-7,000 deaths in the 1920s and 1930s to 1,700 in recent years despite a 16-fold increase in vehicles and 33-fold increase in miles driven. The UK now ranks among the world's safest countries for road travel at 1.9 deaths per 100,000 people. Key interventions included mandatory breathalyzer tests in 1967 that reduced drunk-driving deaths by 82%, the introduction of motorways beginning in 1958, conversion to roundabouts that cut fatal accidents by two-thirds, and 20-mph speed zones around schools. If global road death rates matched Britain's current levels, approximately one million lives would be saved annually from the current 1.2 million road deaths worldwide.
