As far as I can tell, it’s technically illegal but enforcement seems hit-or-miss. It may depend on how the officer who sees you driving on it is feeling that day, and how well they happen to know the law. It may also have less-understood exemptions, like if you had RV plates or weigh < 8000 lbs, but those were secondhand and thirdhand reports. There might also be sections of LSD near McCormick Place that may be exempt. If you want to play it super-safe, best not to drive a pickup there.

What IS clear is that you’re not allowed to park on residential streets, only “business streets”: Pickup Trucks & Commercial Vehicles | Office of the City Clerk

If the non-commercial pick-up truck is owned by a Non-Chicago resident, (e.g. a visitor from the suburbs) and does not have a current and valid City Sticker, the owner may park the vehicle on a Business street.

Commercial pick-up trucks, junk vehicles, and any pick-up truck weighing more than 8,000 pounds are still prohibited from parking on ANY residential and business streets.
