Continuity: There are a number of stock footage continuity errors. The major one is the differences in Squad 51, which was always a Dodge pickup, but several model years were used on the show. Most of the street scene footage that shows the Squad traveling was shot in Season 1, so an older model usually appears that doesn't always match the Squad that leaves the station or arrives at the scene. Another continuity issue is repetitive use of the same response footage episode to episode, so the same cars are always stopped at the same spot at a particular intersection.
