Swedish road signs depict people with realistic (as opposed to stylized) silhouettes.
Swedish warning and prohibition signs also have a thicker border than their European counterparts.
Around 1980, Sweden followed the Vienna convention rule that motorways should have a different colour, so green was introduced for them, and medium blue for ordinary roads.
But if the state pays support for the maintenance, cars can't be prohibited.
The Swedish word for this kind of road is "enskild", that can be both translated to "private" and "individual".
More types of warning signs for animals are used than in most European countries, such as moose, deer, wild boar, reindeer, sheep, horse, and cow appearing alongside roads.
The sign "Stop at customs" ("Stopp vid tull") is multilingual and exists in four variants.
