Continuity mistake: When Squad 51 is dispatched and headed to their destination, interior shots looking out the windshield are shown. It is only in these shots that the Dodge truck's red hood has vents on its right and left sides. There is no such thing in any exterior shots of Squad 51. The hood's style also changes.

Revealing mistake: When Squad 51 is dispatched from the stationhouse, the exterior shots show buildings, traffic, trees, etc., they pass along the way.

How Green Was My Thumb? - S3-E17
Revealing mistake: When Roy brings the man with a laryngeal obstruction into the ER and is taken quickly to treatment 1, his head is tilted back and Early places a laryngoscope into the patient's mouth and says that he sees the obstruction.

Then, when Early uses the forceps to remove the obstruction, once again we can see that it does not go into the patient's mouth.
