On the 3rd of September 1967, Sweden made the historic decision to switch from driving on the left-hand side of the road to the right-hand side. This change was known as Dagen H, with the 'H' standing for "Hogertrafikomlaggningen," which translates to "the right-hand traffic diversion" in English.

This monumental shift was a result of years of planning and preparation by the Swedish government. The decision was made in an effort to align Sweden with its European neighbors, who predominantly drove on the right-hand side of the road. The change was also seen as a way to improve road safety and reduce accidents, as it would eliminate the confusion caused by differing driving practices.

The switch to driving on the right-hand side of the road was not without its challenges. The government launched an extensive public awareness campaign leading up to Dagen H, with advertisements, brochures, and even a song created to help educate the population about the change. On the day of the switch, traffic was halted at 4:50 am, and all vehicles were required to come to a stop. At 5:00 am, traffic resumed, but now on the right-hand side of the road.

Despite initial confusion and some minor accidents, the transition to driving on the right-hand side of the road was ultimately successful. Today, Sweden is known for its safe and efficient road system, with drivers following the right-hand driving rule without issue.
