Continuity mistake: The General Lee is a souped up Dodge Charger, often called a "stock car". As such, it has roll bars mounted inside. Every so often, you see no roll bars in it, meaning that there was more than one General Lee used in the series.
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: After she first boots Rosco, Daisy is driving his car. The close up of her driving you see the right front corner of the truck Rosco commandeered to chase her behind her. Trouble was, that Rosco hadn't gotten the truck yet.
Continuity mistake: When the Sheriff's car approaches the construction area, you see there is no ramp anywhere, and the road area isn't bumpy enough to account for the car flipping and rolling.
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.

Swamp Molly - S1-E6

Continuity mistake: In the previous episode, Boss Hogg had a large brown mole below and to the right of his mouth. In this episode it's gone.
Continuity mistake: As "Sweet Talk" has Jessie and Daisy in the house at gun point, he has the shotgun at waist level. As they hear "Dixie" (the General's horn) the camera cuts in close to "Sweet Talk." He now has the gun at chest level. After he says 'Both of ya just sit still" it's at waist level.
Continuity mistake: When robbing Boss Hogg, the guy ripped the pocket of his jacket. Later at the Boar's Nest, you see the same pocket undamaged. Then when he's in the building, it's ripped again.
Continuity mistake: After the boys jump the bad guys in the chop shop, they pull the guys up, and Luke draws his bow on them. When the camera angle changes, Luke is just drawing his bow again, saying "Uh, uh, uh, uh", warning them to stop.
Continuity mistake: After picking up Marlowe, the deputy with them mentions the car following them. They're out in the wide open area, but the car in the mirror is in the downtown area. Then after a quick cut, they're in the downtown area of Springville again.
Continuity mistake: The boys already had dynamite arrows made up. When they go to stop Marlowe's car, Luke says "Twenty-five percent charge ought to do it." They weren't carrying any extra dynamite, and weren't carrying the bags that held the bows where they would have had the extra charges.
Continuity mistake: The road that the Dukes are travelling on was clear about two minutes before, and the thugs were right behind them. After turning around to go the right way, they find the area they just came through blocked by a semi. No way the truck could have been set there that fast.
Answer: Various reasons, but mainly to drive the Dukes out of Hazzard County because the family have been foiling his schemes since his and Uncle Jesse's bootlegging days.
