50 free Chicago P.D. trivia questions with answers — entertainment quiz, new questions added Aug 2026.
This Chicago P.D. trivia quiz covers Dick Wolf's police procedural from its 2014 premiere through its renewal for a fourteenth season. Expect questions on Sergeant Hank Voight and the Intelligence Unit, the detectives and patrol officers who have passed through the 21st District — Lindsay, Halstead, Upton, Dawson, Olinsky, Ruzek, Burgess, Atwater, Platt and the newer recruits — and the back-stories the show built for them. There are rounds on the One Chicago crossovers with Fire, Med, Justice and Law & Order: SVU, the Old Maxwell Street station house that once stood in for Hill Street Blues, the casting changes before and after the premiere, and the reviews. Early rounds suit casual viewers; later rounds are for fans who know which episode killed Sheldon Jin. Every answer was checked against encyclopaedia entries before publishing.
