Road signs in rural locations in this country urge greater alertness in case of cattle, or wild animals in the woods. But SIKU vehicles are played with all around the world. So it's obvious that road signs warning of other animals on or near the road are also required: bears, elks, kangaroos, kiwis, crocodiles. And if a UFO should land, the aliens will receive a friendly greeting. The signs, produced to the usual SIKU quality out of high-grade plastic, are particularly robust and stable. Thanks to the international warning signs, the SIKU vehicles and SIKUWORLD are able to go on a voyage of discovery to foreign lands and far-flung continents.
