It appears that a Bernie Sanders supporter hacked into some construction signs in the Dallas area.
Drivers traveling along I-30 early Tuesday saw a sign reading "Bernie for President" and another that declared Donald Trump to be a "shape shifting lizard!!"
Another let morning commuters know that work was canceled and instructed them to "go back home."
Earlier in the weekend, a sign reportedly told people to "party hardy, y'all!"
Police believe the signs, operated by a contractor, were reprogrammed manually by someone who broke the locks. They cannot be programmed remotely.
The crime is a misdemeanor, carrying a $1,000 fine and up to two years in jail.
The signs have since been fixed.
