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.
Dukes Meet Cale Yarborough - S2-E7
Visible crew/equipment: When the General Lee makes a great jump (in fact the jump is used in the opening credits of the show starting in season 2), you can see a camera hooked to the bottom of the car on the passenger's side.
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)
Dear Diary - S4-E20
Visible crew/equipment: Here you can easily see a support rod and strap at the rear of the General Lee as it holds the camera.
The Great Bank Robbery - S4-E6
Revealing mistake: The bandits lock Bo and Luke inside closed coffins and then leave. Bo and Luke begin "rocking" the coffins back and forth to tip them over so they can escape. However in the following shots, as Luke is rocking inside his closed coffin, the camera slips or shifts too much, and you can see the barns' interior at the sides of the screen, alongside some equipment.
Other mistake: In the first scene when Bo and Luke are practicing with the General Lee, you see Bo using the clutch, but in the next shot both hands are on the wheel. He didn't have any time to move his hands in about a milisecond.
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.
Road Pirates - S2-E5
Factual error: When Roscoe tries the same jump the Dukes did, his car goes nose first into the wall of the ravine. Upon a close up, Roscoe is fine, but not wearing a seatbelt. According to physics, he should go through the windshield or get cut up.
Gold Fever - S2-E2
Plot hole: Roscoe and Enos are chasing the boys. They are well ahead of the Sheriff and go up into a semi with a conveniently made ramp to lose the cops. The dust was dissipated enough that Roscoe, coming up from the rear, could have seen the General in the trailer. Roscoe couldn't be that blind. Plus the trucker couldn't miss the movements of the truck settling down from the sudden adding of two tons.
Revealing mistake: Bo and Luke Duke's car the "general Lee" usually has no glass in the side windows due the doors being welded shut as per NASCAR regulations which is why they climb through the windows to enter and leave the car, but when the general is doing one of its many jumps, in the long shots there is glass in the side windows.
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.
Audio problem: At the end, as Bo reaches in to honk the General's horn to announce Rosco's arrival, you can see his hand doesn't touch the steering wheel.
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.
Audio problem: During the final run to the Boar's Nest, Luke is driving General Lee. There is one final jump, and you hear Bo's rebel yell, but Bo is at the Boar's Nest.
The Ghost of General Lee - S2-E6
Revealing mistake: When you see Bo and Luke running around "naked", when they go to that girl's house to ask for clothes, while they are leaving you can see a little bit of the blue jeans that Bo was wearing to bring the naked effect to life.
Factual error: Throughout this entire season, Bo and Luke left Hazzard to become Nascar drivers. This wouldn't be allowed as part of their probation legally prevents them from leaving Hazzard County.
Suggested correction: First off, in s01e01, the show starts where it had already been a year since Bo and Luke were put on probation. However, they were only given 5 years probation and this takes place in season 5. However, in the show they were allowed to leave Hazzard County with permission from a parole officer, so even assuming they're still on probation, they could have had permission without showing it on screen.
