A typically forgettable digital traffic sign in downtown Chicago turned into a political sideshow Thursday night, surprising pedestrians and drivers near Lake and Dearborn when it flashed vulgar messages about former President Donald Trump and U.S. Immigration and Customs Enforcement.
The board briefly cycled through the phrases “TRUMP SUCKS” and “F*** ICE” before reverting to its standard messaging, according to footage of the sign that captured the short-lived display.
According to CBS Chicago, the sign is a Chicago Department of Transportation message board in the Loop, and the outlet embedded a short clip of the incident. CDOT did not immediately respond to a request for comment on how the messages wound up on the board, the station reported.
Not The First Time Message Boards Were Hijacked
Hijinks, or outright hacking, of portable and remote message signs is not new in Illinois. In 2019, a portable traffic sign in Rockford was altered to display a profane message aimed at President Trump. City officials told reporters they notified the contractor responsible for the equipment, which then moved to secure the system, as WIFR reported.
What Federal Rules Say And Who Controls The Boards
The U.S. Manual on Uniform Traffic Control Devices classifies changeable message signs as traffic control devices and says they “should not be used to display information other than regulatory, warning, and guidance information related to traffic control.” The MUTCD sets standards for what can appear on those signs and how legible it must be.
Federal guidance also urges agencies to spell out who is actually in charge of the hardware. The Federal Highway Administration’s operations handbook notes that control and maintenance responsibilities for field equipment should be clearly defined in corridor agreements so agencies and contractors know who has operational authority and how to respond if systems are compromised, FHWA says.
Until Chicago officials explain what happened in the Loop, the incident stands as a vivid reminder that public message boards are highly visible pieces of infrastructure, and that secure controls, clear maintenance duties, and fast contractor response are crucial if traffic signs are going to stick to safety instead of straying into politics.
