It turns out the northern lights can be hazardous to humans. Police in Iceland pulled over two different drivers near the airport in Keflavík because they were swerving between lanes, reports Iceland Magazine. Police thought for sure they'd made DWI stops until the drivers, both foreign tourists, explained: They'd looked up and been captivated by the aurora borealis. Police let both go with only warnings, and the magazine dubs the new offense "driving under the influence of the aurora." (More aurora borealis stories.)
