Continuity mistake: After Daisy stops at the tree after Lester and Boss crash, she's facing away from the road. The bad guys and the General go by the spot and are well past Daisy on the right side of the Jeep. After they are past, the camera does a close up on Daisy, and her looking and yelling to the camera "Go get them Bo!" She's not looking in the right direction.

Continuity mistake: When Cooter turns around to go after the bad guys, Enos comes from the side road, sliding a one-eighty. The back end of his car stops against the tow truck, but when the camera goes to a close up on Enos, there is no truck behind him, only trees.

Continuity mistake: After the boat with Jessie, Bo, Luke, and the girl get stuck, you see Jessie standing to get the boat unstuck. A second later, you see that he's sitting, then another second and he's standing.
Audio problem: When Bo and Luke come up behind the visitor in the blue car, Bo honks the horn and waves. When he does, only the last part of "Dixie" plays when the camera is on him. Then the camera cuts to her, and only the last three notes play about two or three seconds later.
