Hacked road signs warn of zombies, raptors ahead

COLLINSVILLE, Ill. – Hackers are messing with electronic road signs in some states, warning of zombies and raptors down the road. Traffic safety officials aren't amused. The latest breach came during Tuesday morning's rush hour near Collinsville, Ill., east of St. Louis. That's where hackers changed a sign along southbound Interstate 255 to read, "DAILY LANE CLOSURES DUE TO ZOMBIES."

Similar pranks have been pulled in recent days near Indianapolis and in Austin, Texas.

The Illinois Department of Transportation's Joe Gasaway worries that such pranks distract drivers from legitimate hazards down the road, perhaps endangering road crews.

In Illinois, tampering with an official traffic control device is a misdemeanor punishable by up to a $250 fine.
