An electronic DOT road sign was apparently hacked when a displayed message read "Impeach Obama."

DOT officials told WSOC they had not heard of the display when first contacted on Sunday night, but sent an engineer to correct the sign afterward.

The sign, which was located at the intersection of Unionville-Indian Trail and Ridge roads in Union County, was displayed for an unknown amount of time over the weekend and corrected later Sunday evening.

Several drivers stopped to take pictures of the message.

Electronic road signs were also hacked earlier this year in Rock Hill, S.C. Previously-hacked signs warned of zombies, hunters and tanks in the roadway.
