La 04:50 toată lumea s-a oprit. La 05:00 o țară întreagă conducea pe contrasens

In September 1967, Sweden underwent a significant traffic change known as Dagen H, shifting from left to right-hand driving. Despite initial resistance, with 82.9% opposing the change in a 1955 referendum, the government proceeded with the transition. A massive public awareness campaign preceded the event, which took place on September 3rd. At 5:00 AM, vehicles switched sides without chaos, leading to a notable decrease in traffic fatalities that year. The careful approach of drivers, aware of the change, contributed to the smooth transition, marking a historic moment in Swedish transportation.
