what side of the street do they drive on in sweden
Left- and right-hand traffic Sweden was LHT from about 1734 to 1967,[17] despite having land borders with RHT countries, and approximately 90 percent of cars being left-hand drive (LHD) vehicles.[18] A referendum was held in 1955, with an overwhelming majority voting against a change to RHT. Nevertheless, some years later the government ordered a conversion, which took place at 5 am on Sunday, 3 September 1967. The accident rate dropped sharply after the change,[19] but soon rose back to near its original level.[20] The day was known as Dagen H ("H-Day"), the 'H' being for HÃ¶gertrafik or right traffic. When Iceland switched the following year, it was known as H-dagurinn, again meaning "H-Day".[21]
