Other mistake: When we first see a shot of Bandit's CB radio, you'll notice that it's a Pace Cb-166, and the microphone has a circular Pace logo. Later in the movie when Bandit picks up Frog, and he's holding the mic up as she's rambling to trying to get off her wedding dress, you'll see the mic has a different rectangular logo (still a Pace model mic, but different from the one initially shown. (00:18:06 - 00:25:13)
Other mistake: Bandit and Snowman are traveling to Texarkana, TX to pick up the beer. Texarkana is in the extreme East border of TX. When you see Sheriff Justice pull up to the guys trying to steal parts off Frog's broken down car, you see "Montague County Sheriff" on his police car door. Montague county is in Northern TX, about four hours away from Texarkana. Bandit and Snowman didn't travel that far into TX to pick up the beer, why would Sheriff Justice be so far away from his jurisdiction?
Continuity mistake: Sheriff Buford T. Justice gets out of his car and leaves the door open. A few moments later, we see a different shot of the car with the door closed. Then a truck drives by and tears the car door off which is open again.
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: In the scene near the end Snowman drives a truck into a load of police cars if you play it in slow motion you can see a protector around the lights.
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: In the scene where the tractor trailer and the Trans Am meet up at Ole Miss, We see the Trans Am stop a ways ahead of the rig. In the next shot the Trans Am is closer than before.
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)
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!
Visible crew/equipment: When Snowman stops off at the diner, when he enters and leaves from the diner, various crew-members and equipment are visible in the windows on the doors.
Factual error: They go to Texarkana Texas to pick up the beer and later in the movie they are in Fayetteville Arkansas. Why would they go due north to Fayetteville to get to Atlanta which is due East?
