Drivers: watch out for polar bears

New signs for the Svalbard islands off the extreme northern coast of Norway warn drivers to watch out for polar bears. The signs are posted along 40 km of roadway.

The previous signs showed a polar bear in black against a white background, however, the new signs show a white bear against a black background.

Officials hope the new signs will remain in place because the old signs were popular souvenir items for tourists.
