Continuity mistake: Bo is waiting for Luke's escapade with Laurie, and meanwhile listens to Al Unser Jr.'s story narrated by Laurence Fishburne. He checks out of the case of the tape propping it against the left or the right of the steering wheel depending on the camera angle. (00:02:40)

The shirt goes through other various stages of sweatiness throughout the Boar's Nest scene. (00:09:30)
Continuity mistake: After Bo has brought Billy Prickett a pint of beer, the beer glass keeps moving as evident by the handle changing its direction. Also the pint is completely full, but when Bo picks it up to drink from it (before attacking Dil) it is half full. (00:12:45)
Continuity mistake: When Sheriff Rosco enters the bar and the Duke boys stand in front of him, in the shot from behind Bo loosens the strap of the helmet he is wearing but does not unclip it. In the next shot it is suddenly unclipped and loose, and he then removes the helmet. (00:15:50)
Continuity mistake: When Cooter (the engineer) goes over to his desk to make a phonecall, after Sheriff Rosco has left, the items on the desk completely change their position between shots. (00:24:55)
Continuity mistake: When Luke is trying to pull the safe free from behind the telephone pole, watch the chain that the safe is attached to. It keeps changing from being on the left side of the pole, to the right side and back again. (00:28:00)
Continuity mistake: When Boss Hogg is cooking in the bar, the ingredients on the side and on the chopping board change position, most noticeable is the onion. (00:30:20)

Continuity mistake: The arrangement of the core samples in the safe changes, just after Sheev walks away. The two samples in the bottom left move to being in the centre. (00:36:50)
Continuity mistake: When the police cars pull up outside Cooters, just as the Duke's drive out with the fixed General Lee, the position of the police cars keep changing (note it's position in relation with the parking markings.) (00:37:25)
Continuity mistake: When the Duke's are in General Lee on the highway, people pass in their vehicles and shout at them. In some shots Bo has his hands on the steering wheel and in some shots they aren't. (00:40:35)
Continuity mistake: When Billy Prickett walks into the back garage to find Sheriff Rosco and Boss Hogg, there is a car beisde them with a white sheet over it. During shots, the large creases in this white sheet keep changing. (00:42:30)
