Continuity mistake: When being chased at the beginning it is raining. When he ducks in behind the building there's no sign it's been raining and T-top convertibles are out driving.
Continuity mistake: When Buford hits the back of Sheriff Branford's car on the bridge the hood of his own car is bent upwards in the middle but the next time we see Buford's car the hood is back to normal.
Plot hole: Bandit and Snowman must have special powers to accomplish their round trip 1800 mile journey in the time they do. For starters when they begin the trip in Georgia it's sometime in the afternoon, and we later see them travelling at night before arriving at the Coors facility in Texarkana the next morning. This means the majority of their 28 hour window was spent getting TO Texarkana. So how is it they were able to both make the 900 mile trip back to Georgia while making all the stops they had to make, avoid all the smokies chasing Bandit off his path and give Bandit and Carrie time to be romantic all with only a few hours to spare after leaving Texarkana? At the very least it should have been late event or night time when they got back to their destination in Georgia.
Continuity mistake: When the Bandit first pulls over and picks up Sally Field, then he screeches off, if you look at the road you can see all the skid marks from all of the other takes of this scene, even down to the bit where the van pulls out of the junction and the bandit does his thing and then suddenly speeds off.
Continuity mistake: When the Bandit and Frog make the jump onto the field where the kids are playing football, the Trans Am goes through a chain linked fence then under a score stand. As it emerges through the wall, the antenna is broken, lying rearward onto the rear glass. The very next shot from the other side shows the antenna is fine and a few wood boards are around it. And when the boards fall off, this antenna falls off completely. The next time we see the car, a third antenna is in place again.
Continuity mistake: When The Bandit is getting ready to get in the convoy of trucks, right before he gets in between the trucks, all the trucks are close together. When they show a closeup inside the car, you can see the trucks are farther apart when you look out he back window. In the next shot when the cop car is pulling up, the trucks are close to each other once again. (01:16:35)TiggBoy
Continuity mistake: The odometer in the Trans Am is shown to have 1108.8 miles on it, rolling on up to 1108.9 during the shot. A little later during the movie, after they have travelled a considerable amount of miles, Bandit says, "We'll let's just see what he's got under the hood." A close-up of the speedometer shows the odometer is still on 1108.9.
Revealing mistake: In the scene where the Trans Am is hiding among the truck convoy, you can see that the vehicles are all on the wrong side of the highway, as if to let the camera vehicle travel on the normal side of the highway. Notice the missing westbound lanes in the background as the vehicles are pointing directly to the viewer's right...then the lanes are back when the vehicles are shown from the front or rear.
Continuity mistake: In the scene where Buford T Justice is waiting in line behind a bunch of cars stopped at a car accident (in Alabama) there is a green Cadillac behind him, when he pulls off to the side to try getting through and gets stopped by the trooper, the same Cadillac is in the front of the line. At the very end of the film, when Bandit and Smokey are talking on CBs to each other, the same Cadillac is parked in the background, ahead of the red convertible that Bandit is driving...now in Georgia!
