For everyone claiming driving away from an unmarked ICE vehicle is “fleeing”…
Per the Illinois Rules of the Road handbook:
“If you cannot identify an unmarked police vehicle and/or the driver as law enforcement, you should drive slowly and carefully below the speed limit and either (1) pull over at a well‑lit, populated location, (2) drive carefully to the nearest police station and attempt to attract the attention of a uniformed officer.”
Courts have consistently held that in order to be guilty of “fleeing and eluding” the police, the police car must be “marked.”
