In Sweden, every student that finishes high school are celebrating the day they graduate high school.
Its usual to see people riding their cars, honking and holding signs of the graduating students. They signs they hold up for display are pictures of the student when they were young (usually at the age they just started school or when they were babies).
Most usually the graduating class book together a big truck where they celebrate together with loud music while they ride together throughout the city displaying and celebrating their happiness.
