An electronic message board on Interstate 80 near Dixon was hacked, allowing someone to type a few words about President Trump.A KCRA 3 viewer sent in a photo of the sign on Thursday night, which reads, "Trump has herpes."The hacked sign was originally used to warn drivers about a major road project happening on the Pioneer Bridge. Because of the hack, motorists are not seeing the warning."That's an important message for motorists, so they can plan for congestion or take alternate routes," Caltrans spokesperson Gilbert Mohtes-Chan said. This isn't the first time a construction sign has been hacked in recent months. A Caltrans sign in Napa was hacked in July to say, "caution asian drivers."In February 2014, a construction sign on Auburn Folsom Road in Granite Bay was changed to something so offensive, it couldn't be shown or blurred on TV, but it referred to human body parts.The hacker's message was so obscene that the Placer County Sheriff's Department was called, and officials shut down the board until it could be reprogrammed.On Thursday, dozens of drivers were tweeting and taking pictures of the message on the I-80 board. Caltrans said that's a concern."False information can be a distraction and a roadside hazard as well," Mohtes-Chan said. Caltrans said it secures each sign with a lock and a secret code. "We continue to make an effort to make these secure and also to prevent, with more secure passwords, to prevent these things from happening," Mohtes-Chan said.The agency is still investigating out how the hacker changed I-80 sign.
