What color is the center of a Swedish warning road sign?

The center of a Swedish warning road sign is yellow.

Swedish warning signs typically place a black hazard symbol on a yellow background surrounded by a red border. The yellow field is one of the easiest ways to distinguish Sweden’s warning signs from the white-background warning signs common in much of continental Europe.

This design is used for hazards such as bends, crossroads, pedestrians, cyclists, animals, and roadworks. The sign warns road users to expect a condition ahead; any required speed reduction or other legal instruction may be supplied by a separate regulatory sign or by general traffic rules.

Color choices are not universal, even when the symbols are similar. Sweden’s signs fit broad European conventions while preserving national details, and neighboring Finland uses a comparable yellow warning background. Travelers should therefore learn both the symbol and the local color system.
