Why Sweden abandoned left-hand driving for the right-hand side
In short: In a massive logistical undertaking known as Högertrafikomläggningen, Sweden transitioned its entire nation from driving on the left to driving on the right.
The shift, called the 'right hand traffic diversion,' was not a sudden impulse but a transition planned for years. At the time, Sweden was the only nation in Continental Europe that still drove on the left.
Decision-makers were motivated by safety concerns, specifically the perception that driving on the left while having the steering wheel on the left side of the vehicle increased the risk of head-on collisions.
