As the Midsummer celebrations approach, Swedish authorities are warning drivers about a deadly mistake on the roads.

Traffic accidents increase by 30% during Midsummer compared to regular summer days.

A common cause is being hit from behind, often from drivers stopping improperly and staying inside their vehicles.

Officials urge drivers to leave their vehicle and move 10-15 meters away after setting up a warning triangle.

Driving cautiously and staying focused can prevent these dangerous rear-end collisions and other severe accidents.
