First morning after Sweden changed from driving on the left side to driving on the right, 1967
There were various arguments for the change:
1. All neighboring countries drive on the right, including Norway and Finland, with which Sweden shares land borders, with five million vehicles crossing annually.
2. Approximately 90 percent of Swedes drove left-hand drive vehicles, and this led to many head-on collisions when passing on narrow two-lane highways. City buses were among the very few vehicles that conformed to the normal opposite-steering wheel rule, being right-hand drive (RHD).
