Days of Shine and Roses - S2-E1
Continuity mistake: When Rosco goes into the trees after the boys run him off the road, the amount of damage to the car is negligible, yet at the end, the car is crushed in on the sides.
Days of Shine and Roses - S2-E1
Other mistake: When the General does a jump during their shortcut, it goes through a tree, and lands mostly on the left side of the car, but the next shot, it's still going.
Days of Shine and Roses - S2-E1
Continuity mistake: When Rosco gets out of the car with the Detour sign, the arrow points to the right, the way Boss went. When he sets the sign up, it points left. Then after Luke grabs it and sets it out ahead of Jessie, it points back to the right.
Days of Shine and Roses - S2-E1
Revealing mistake: When watching the film in the beginning, one of the cops pursuing Jessie and Boss rolls over. As he does so, you can see the roll bars in the car, which accounts for the car not crushing.
Days of Shine and Roses - S2-E1
Revealing mistake: When "Spike" goes to pull the front fender of the car off, you can see the square outline of the spot meant for the spike.
Days of Shine and Roses - S2-E1
Revealing mistake: As Sheriff "Spike" Loomis goes to put the railroad spike into the car's door, there is a square outline of the spot set up for him to put the spike.
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.
Gold Fever - S2-E2
Revealing mistake: Toward the beginning, when the Dukes meet the Texans, when the Texans toss up shot glasses to shoot, you see a white wire attached to one of them, probably to bust the glass on cue.
Gold Fever - S2-E2
Continuity mistake: As the Dukes meet the limo, a closeup shows Jesse lying over to his right. When they stop, Jesse is sitting up, then lies over to the right again.
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.
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.
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 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.
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.
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.
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.
Continuity mistake: When Luke is slamming into the smugglers with "the Slammer" car they show a close up side shot of Luke turning into them. In this close up he is driving the general lee, then it cuts back to the slammer.
Continuity mistake: When in town, the boys see Enos coming out of the courthouse. They go to get out to get Granny Annie, you see Bo in the driver's side. After they see Roscoe and take off, they do the "skiing" (driving on two wheels) thing. When the General Lee sets back down on all fours, you see a blue shirt in the driver's window, suggesting that Luke is driving.
Audio problem: In the Boar's Nest, when the Oak Ridge Boys are singing, you hear a familiar "Yeee-haw!" This is from Bo, and you hear it now and again, even when you see Bo in a close up, and his mouth doesn't move.
Continuity mistake: When the Dukes meet up with BB, they come from a side road onto the main road. When the shot goes in to a close up on BB, you don't see a side road. And half the time, you don't see any dust kicked up by the opposing vehicles.
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.
