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.
Visible crew/equipment: After the fertilizer truck carrying slot machines is intercepted, when Daisy runs off just as Luke and Bo place hoods on the men, two white tape marks are visible on the ground where Daisy had been standing. (00:16:30)
Other mistake: When Enos is chasing the boys through the town square, you see the General Lee parked in a parking spot, but the POV is meant to be from the General Lee.
Swamp Molly - S1-E6
Audio problem: In Hogg's office in the Boar's Nest, after Roscoe tells of the activities, Boss goes to put the needle back on the record. Trouble is, the record doesn't move until Boss turns it, but the music started before the record moved.
Route 7-11 - S1-E12
Visible crew/equipment: At the farm, Luke is trying to sweet talk Jesse. As Luke crouches, the shadow of the boom mike is moving on the wall.
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.
Visible crew/equipment: As Bo gets out of the General at the orphanage, you see the light panel reflected on the vent window, and the shadow of the camera and operator on the ground at the bottom left of the shot.
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.
Audio problem: As Jesse, Bo and Luke are about to leave after Jesse bails them out, Jesse says "C'mon." It's voiced by someone else. (00:05:50)
Swamp Molly - S1-E6
Revealing mistake: When the truck goes into the water, you can see the driver was either a stunt driver or a dummy. Also, you can see the top of the truck just under the surface of the water, suggesting it was on the bottom. A few seconds later, and all you can see are bubbles.
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.
Other mistake: When the camera is close up on McQuade, you can see the cylinder of his pistol is empty.
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)
Route 7-11 - S1-E12
Character mistake: In this episode, they constantly refer to the semi as an eighteen wheeler. The tractor would have tandem (two) rear axles with dual tires. This one has only one rear axle on the tractor. Added up, the rig only has fourteen wheels.
Route 7-11 - S1-E12
Other mistake: In the opening sequence, there's a shot from on top of the General Lee. As they do a one-eighty, you can see skid marks on the road where they have done other turns.
Visible crew/equipment: When the hearse is pulled up to the coffin works, the driver is left alone to look at his map. If you look to his left, you can see the reflection of the lighting rig.
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.
Factual error: While the boys are chasing Marlowe in town after he takes Price's gun, he fires at them. He fires eight shots out of a six shooter without reloading. Also, Luke puts an arrow into the car to stop Marlowe, and steam comes out. But the arrow is too far back to have hit the radiator, and it only went in about an inch, far too high to have even touched the radiator.
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.
