Continuity mistake: When Roscoe and the judge are in the court room and the town comes to object the strip mine ordinance, the courtroom doors are held shut by a night stick. When the townspeople start to shake the doors you can see that the night stick slides to an angle, then when they cut to a closer view the night stick is level once again.
Revealing mistake: There is one shot of the Duke boys in their car talking to Uncle Jessie with the CB radio. You can hear Uncle Jessie respond (through the radio) while Bo/Luke still has the button on the microphone pressed. When the button on the mic is pressed, no sound comes out of a CB radio at all, as they cannot transmit and receive at the same time.

Continuity mistake: The Dukes are being chased through a field by countless police cars. The car is kicking up mud and dirt and getting dirty. Eventually the General nails a police car on the right front end (left side facing the film viewer). The car is catapulted up onto two wheels and the General miraculously slides through a barn. However, even more miraculous is as the General goes into the barn, the car is completely polished and shows no front end damage at all. The car leaves the barn in pristine condition.
Continuity mistake: When Bo and Luke pick up the General Lee when Cooter has finished fixing it, there are shots flashing between different parts of the new General. One of the shots is of the word Charger, which is located on the headlight cover when it is closed, but in all the shots before and after the headlight cover is open.
Visible crew/equipment: After escaping (with Daisy's help) from the back of the cruiser, as they are being chased, the sun casts a shadow of the camera and equipment. It can be seen on Bo's shirt as they "drift" through the first circle. This is before the big drift scene when Bo keeps driving around and around the circle.
Continuity mistake: When Luke and Uncle Jesse are in Boss Hoggs' car, in the racing scene towards the end of the movie, Jesse is just about to start lighting and throwing the jars of moonshine. Just before he does, when he takes a drink from one his right hand is holding the cap on his head and the jar is in his left, but in the next shot the jar is in his right hand and the cap is in the left.
Revealing mistake: In the scene where the Duke Boys are driving to Atlanta to have the core samples tested, they are on the interstate and the people are commenting about the roof of the car. If you notice the Boys are higher then the passage cars, but with other shots you can see they are at the same height as the other cars on the road.Most likely this would happen with the car being filmed on a trailer going down the interstate.
Continuity mistake: After the boys run five miles to the Boar's Nest, the sweat stains on Bo's blue t-shirt starts disappearing and reappearing. When Bo gives a beer to Billy Prickett, his shirt is dry in one shot, and then again has a wet sweat stain in the next. The shirt goes through other various stages of sweatiness throughout the Boar's Nest scene.
Visible crew/equipment: When Bo and Luke are talking to the geology student, and Katy Johnson pops in the door to hurry them up, just after she dances for Luke in the doorway, the camera pans back to Bo and Luke. Just then, a boom mic pops into frame at the top of the screen, then quickly moves back out.
Continuity mistake: Towards the beginning, after Bow and Luke make there delivery to Laurie. Bow and Luke run away from Mr. Pullman(Laurie's Pa) and the brother. The son fires a shotgun at the Dukes from the right side of the truck and when he hits Mr. Pullman with gun, he fires, but the hole ends up on the left side of the car. Which is impossible with the angle he was shooting from.
Continuity mistake: During the prison scene while Boss Hogg is talking to the Dukes some guy behind them in the cell keeps making fun of Boss. Boss Hogg finally pulls a hundred dollar bill out with his left hand and says he'll give it to whoever knocks that guy out. When the camera cuts behind Boss Hogg he is now holding it in his right hand, with no time to have changed hands.
