Instead of a typical “Road Work Ahead” or “Slow” message, the sign read “Angry Raccoons Ahead.”

Mike Biggs, owner of Spokane Traffic Control, Inc., the company that provided the sign, told Fox News Digital in a phone interview that the sign had been hacked.

The culprit, he said, has not been identified.

“I’ve gotten quite a few laughs,” Beggs told Fox News Digital.

This was the first time one of his signs had been hacked to display a different message than the one intended — and he is worried the culprit may strike again.

“You just never know,” he said.

Beggs was unsure how exactly the sign was hacked, or what it was originally supposed to read.

He told Fox News Digital that the signs have “three or four compartments” that could be opened with a bit of finesse.

“So if you’re in this field at all, or have been around them at all, almost anybody,” he said, could change the message on the sign.

Beggs joked that the vandal “sure picked the right phrase” to use on the sign, as the story has taken off far beyond Spokane.

“They could have been a lot more brutal,” he said — noting that there have been “horror stories” of signs in other places being hacked to display messages that are inappropriate.

“It could have been worse,” he said.
