The Ghost of General Lee - S2-E6
Continuity mistake: When the bad guys from Sweetwater county try to steal Boss' safe, you see them pushing it up a ramp into the pickup truck. But in the next shot, when Daisy calls the operator, the safe is in the corner. And when Bo and Luke go to untie Daisy, the safe is gone.
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: When Daisy is helping Luke chase down Benny the Quill, she begins with white open-toe heels, then she is shown wearing running shoes across the rocks in the river, and goes back to the heels just before she falls in the quicksand.
Dear Diary - S4-E20
Continuity mistake: While it's forgiven that the Generals usually have subtle changes through episodes and the series, in this episode we see a General with extremely inconsistent graphics when Bo and Luke deliver the counterfeit money to Winston. The 0 is off and the bottom of the 1 is extremely long.
10 Million Dollar Sheriff (1) - S4-E8
Continuity mistake: In the first scene that Steele is chasing the Dukes in, he hits the side of the General Lee. You can see that the side is badly damaged. But in the next shot when the General Lee is taking a sharp turn and sliding, you can see that the car is repaired.
Double Dukes - S4-E2
Continuity mistake: If you look closely during the first scene where Turk and Moody (disguised as Bo and Luke) reveal to Roscoe that they aren't Bo and Luke, as they peel off their faces. First Moody (as Luke) is wearing a solid light-blue shirt. When we get a close-up of his face, he is wearing Luke's traditional blue-pladed shirt, and after their masks are totally off, Moody is wearing the solid light-blue shirt again.
Dukes Meet Cale Yarborough - S2-E7
Continuity mistake: While being chased by Roscoe in the beginning, the close ups of Bo and Luke don't show anyone behind them. Yet the long shots show Roscoe right behind them.
Road Pirates - S2-E5
Continuity mistake: When the boys and Cletus are being chased by Roscoe, they use the nitro. When the car is jumping the creek, as it is seen from the back before it lands, you can see one person wearing the Deputy hat. This shot was re-used from the beginning of the episode.
The Meeting - S2-E4
Continuity mistake: After Boss and Roscoe come down to the jail where the Dukes have the mobsters trapped, Boss pulls out a cigar. After the camera cuts a wide shot, the cigar is missing. Then Boss pulls out the cigar again.
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: 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.
Daisy's Song - S1-E2
Continuity mistake: In the close up shots of the General during the junkyard chase, Daisy is sitting between the boys. In the shots from the car being chased, she appears to be in the back seat, looking over Luke's left shoulder.
Continuity mistake: As Bo and Luke pull up to the wrecked Sheriff's car, the roll bars are not in the General. As Bo climbs out, the bars are suddenly there.
High Octane - S1-E5
Continuity mistake: As Bo and Luke are talking to Cooter, from a distance Bo raises the coil of copper tubing chest high on Jessie. After the angle change, Bo raises the copper tubing again.
Continuity mistake: Enos posts up an "Armed Robbery" poster for Floyd Baker and Molly Harmon for a $10,000 reward but after he rips it off the wall after he sees them outside the courthouse it turns into a wanted poster for "Grand Larceny and Car Stripping" for Bo, Luke and Daisy Duke. (00:03:50 - 00:09:55)
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.
Continuity mistake: When the thug's car lands, you see it hit the ground in the distance shot. Then in the close up from the car mounted camera, you see it hit again.
Continuity mistake: During the chase with the blue car, Price's hat goes on and off several times.
Continuity mistake: While running from the blue car, the area behind the Sheriff's car is an open area with a tan truck behind them. After the cut to watch the cars turn, the background area changes to the town, and the tan truck is gone. Also, Springville has all dirt roads, but during the chase, they run off the dirt and you can see the roads and buildings of Hazzard.
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.
