The challenge
Hundreds of people were killed on Swedish roads every year, and blaming drivers had stopped working.
The case
In October 1997 the Swedish Parliament passed a road safety bill built on Vision Zero: the long-term aim that nobody is killed or seriously injured on the roads. The policy shifted responsibility from road users to the people who design the system. Roads were rebuilt so that human error would not be fatal, with measures such as median barriers on rural roads, roundabouts and lower urban speed limits. In 1996 and 1997 roughly 540 people died on Swedish roads each year. In 2019 the toll fell to 221, its lowest level, and Sweden had 22 road deaths per million inhabitants, the lowest rate in the EU.
Why it worked
Treating deaths as a design failure rather than a driver failure put money into barriers and speed control, which work even when people make mistakes. Statisticians note that weather and the economy also move yearly totals, so the long-run trend matters more than any single year.
