Continuity mistake: When Johnny starts chasing Harriet down the street, in Johnny's closeup when he passes the white house (right after the yellow house), there is a light colored wagon-style car parked in the driveway, but in shots from other angles there is a green 2-door parked in that driveway.
Continuity mistake: Roy and Johnny move a barking dog, who is tied up in front of a hermit's rock-faced cave, and retie the dog to a branch in some bushes, but in following close-ups of the dog he is still tied up at the original spot.

Continuity mistake: When the boy who ingested ant poison is laid down on the gurney, the safety belt is wound around the gurney's side bar and clasped, but when exiting the house and loaded into the ambulance the safety belt is directly around the boy.
Continuity mistake: When Johnny goes to the closet to get the mop, because he's 'latrine officer of the day', he gets hit by the phantom, and all the guys run out of the kitchen to see Johnny wet again, so when dispatch drops the tones they all head for the vehicles and Captain Stanley removes his jacket. Then next shot all the guys are running out of the kitchen, as if they were all still there, and Stanley is wearing his jacket.
Other mistake: When Battalion 5 orders Copter 10 and Copter 14 to make an air drop on Jawbone Canyon, it cuts to a shot of Copter 14 taking off. This is the same shot used in S3, E6, "Snakebite", when 85's guys tank Copter 14 in order to make a water drop where the teenagers' car is on fire down below.
Continuity mistake: When Johnny adjusts his IV after the snakebite, he tells Captain Stanley that he's ready to leave, and Chet is not wearing his helmet, but in the next shot as Marco heads for the squad Chet is wearing the helmet.
Continuity mistake: When Johnny is bitten by the rattlesnake he's holding the handie-talkie, but then he drops it and the HT falls to the other side of the car, as he hoists himself up against the car door. However, when he sits down on the ground he is still holding the handie-talkie.
Continuity mistake: At the rock quarry, after Johnny tells Captain Stanley that they need the Stokes and a jack, Johnny removes his helmet, and while Jason holds Johnny's helmet, Johnny tosses the rope below, but in following shots Johnny's wearing the helmet again.
Visible crew/equipment: When Johnny works on the woman in the airplane wreck and says that he'll get the radio, and then when Johnny gets into the ambulance with Angie, the outline of the mic transmitter is visible on the back of his shirt.

Continuity mistake: When they bring the Hermit into the ER, Brackett tells them to take him to treatment 4 and he's wheeled there, but in the shot from inside the treatment room we see that he's actually inside treatment 1.

Propinquity - S3-E20
Continuity mistake: In the opening rescue where Roy and Johnny rescue the woman from the burning car, Johnny is relaying the woman's vitals to Rampart. Over his right shoulder, you can see a sticker on the trunk of the car behind them. This is probably a dealer sticker. In one scene, it is blue and red, and in another, it is blacked out. It returns to blue and red, only to be blacked out again.
Revealing mistake: While 51's guys are on the roof of the construction accident, when Truck 8 rolls up on scene and then places its outriggers we can see the red vinyl material adhered to back of the engine, covering its real company number.
The Promise - S3-E11

Revealing mistake: When Roy and Johnny are at the nurses' station with Dix, Roy decides to deliver the plant that was left for Mrs. Johnson so he and Johnny get into the elevator, and when Roy says, "Six," the floor indicator light on the control panel turns itself on before Johnny even presses the 6th floor button. That light would not turn on if someone up on the 6th floor pressed for the elevator.
How Green Was My Thumb? - S3-E17
Continuity mistake: In the first shot as the engine and squad roll up to the winery fire, the entire trailer with the wood barrels is engulfed in flames with huge plumes of black smoke, but when it cuts to the next shot the trailer and barrels are fine, and there's only a very small fire burning on the ground while Marco pulls the hose off the engine, before the explosion.
How Green Was My Thumb? - S3-E17
Continuity mistake: When the squad and engine roll up on scene at the winery fire, there are wood barrels at the back of the burning trailer, and in consecutive shots the short barrel at the back left corner suddenly appears out of nowhere, then disappears, and then it reappears again.
Continuity mistake: While Roy and Johnny are working on the guy who fell from the horse, since Roy's hands are busy he has the IV line dangling from his mouth before setting up the patient's IV, and in wide shots the cannula is dangling at the left side of his mouth, but in closeups the IV line and cannula have switched sides.
