Continuity mistake: The chase with Daisy in Rosco's squad car ends with a piano slamming into the car. When the truck hauling it comes to a stop, there's a reaction shot of Daisy at the wheel of the squad car. In the next shot, when the piano hits it, the car is empty. A second later, Rosco gets out of the truck and Daisy is back in the driver's seat. (00:30:00)
Continuity mistake: In the opening scene, first the Sheriff's car, then the General land at a forty-five degree angle. You see the Sheriff's car looking like it has a definite bow downward in the middle. The General gets a compression dent over the front wheel well, but later it is smooth down the side.
Continuity mistake: When the Sheriff's car is being chased in the beginning, you can see that the driver is wearing a ball cap. At one point, you can see the hat the unknown driver wears turns to the hat worn by Rosco, as you can see the brim. Later, it's revealed that the unknown driver was Cooter.
Revealing mistake: As the Sheriff's cars are nearing the area where the Mobile Madam is, they're driving fast. As the RV and Bo are nearing the gate of the property they're on, you can see the two Sheriff's cars sitting just to the left of frame, then just beginning to move to make the pursuit look good.
