On September 3, 1967, Sweden made a major change to the way they drive. After over a hundred years of driving on the left-hand side of the road, they switched to the right-hand side. This was a major change for the Swedish people, as it required retraining of drivers, and modifications to roads, signs, and cars.

It was a massive operation that involved the Swedish government and police, as well as countless organizations, volunteers, and citizens. The switch was completed in a single day and went off without a major incident.

The switch was a huge success, and today Sweden is one of the many countries that drive on the right-hand side of the road.
