Danger! Moose Eats Car?

We're not exactly sure what this sign really means — does it mean we should watch out for some kind of super moose that can destroy cars just by breathing on them? Maybe there's an undead moose with a hole in his head from some moose-hunter that's sniffing around demolished cars sitting on the side of the road looking for fresh brains? Whatever it may be, we're really confused. [via Culture Garage]
