Crime levels are low although there is some petty crime. Violent crime does occur, with instances of gang related crime being reported in Gothenburg and Malmö. Pick pocketing can be a problem in the major cities when tourists are targeted for passports and cash.
Sweden deals with its harsh weather very well, but delayed trains and flights are difficult to avoid during severe weather conditions. Snow and ice on the roads cause accidents daily. Consider starting your journey earlier to avoid rushing to your destination. Be prepared for harsh conditions particularly in the north during the winter.
From 1 December to 31 March and when weather conditions are wintry, all Swedish and foreign registered vehicles, both light and heavy, are required by law to have either studded tyres or un-studded friction tyres bearing the following mark, M+S, M-s, M.S, M&S, MS or Mud and Snow.
The road conditions are considered to be wintry when there is snow, ice, slush or frost on any part of the road. The Swedish police decides whether there are wintry conditions on a certain road.
In 2013 there were 260 road deaths in Sweden (source DfT.) This equates to 2.7 road deaths per 100,000 of population and compares to the UK average of 2.7 road deaths per 100,000 of population in 2013.
