Other mistake: 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?
Other mistake: When the Snowman is figuring out their schedule and he is typing on the calculator, you can clearly see that it's off. (00:18:15)
Factual error: When Justice is talking to Sheriff Branford of Deason County Arkansas, Justice is told that he is out of his Texas jurisdiction. But a sign behind Branford tells us that Branford is also a long way from home, as the sign indicates he is in Willow Bend, Clayton County, in Georgia (where this scene was actually filmed).
Continuity mistake: In the scene where Bandit is pulled off to the side of the road waiting for Snowman to pass (just before they pick up the Coors), his Trans Am has Pontiac "Honeycomb" wheels while the rest of the movie the car has Pontiac "Snowflake" wheels. (00:15:40)
Continuity mistake: When sheriff Justice stops the kids in the van, his gun belt keeps appearing and disappearing. (00:22:25)
Continuity mistake: In the scenes where Sally Fields is removing her wedding dress and veil and throws them out of the car you watch the veil leave the car and fly away, in the very next scene the veil is back inside the car as she struggles to get it to fly out of the car again, as it is caught on the t-top.
Continuity mistake: When Buford T. Justice's top gets knocked off his car, at the end of the shot his head starts to emerge from the car and some sunglasses but when the car stops a split second later Buford isn't wearing any glasses.
Continuity mistake: When Sheriff Justice is held up by the funeral procession, he has lost the wing mirror on the driver's side of his car. However, after this it is back on.
Continuity mistake: Every time they show how fast the car is driving, there's fewer miles on the odometer...
Continuity mistake: In the scene where Bandit and Frog are being chased down a dirt road and discover that the bridge is out, they pull a u-turn and you can see there is no back license plate on the car.
Continuity mistake: In different scenes the rear view mirror is shown and then it is gone. This happens several times throughout the movie.
Visible crew/equipment: When Snowman is pulled over by "Mr. Evil Knievel" (the cop) two lighting reflections can be seen in his helmet.
Continuity mistake: Towards the end of the film, Bandit and Frog are coming up on a convoy, which hides them. As the Bandit approches the trucks, he passes the same orange VW Beetle at least twice.
Continuity mistake: When Bandit and Frog are in the park, before he takes his hat off, Bandit is wearing some sort of belt or brace under his shirt. It does not appear in any of the previous or later scenes. (01:04:45)
Continuity mistake: While at the truck stop to refuel, the Bandit talks to Justice on the CB. During this scene, Justice is having his car worked on the front is up on a jack. When the bandit drives by them to leave, you can see Junior is wide awake (in fact, his head turns to look at the car) and then immediately in the next shot he is sleeping.
Continuity mistake: When Snowman plows into Sheriff Justice, he causes Buford's car to spin clockwise. In the very next shot, Buford is spinning counter-clockwise. If this were to happen in real time, Buford would have rolled over. (00:32:45)
Revealing mistake: In the chase scene with the cop taking a "10-100," the patrol car loses control and goes backwards into a lake. But if you look closely as it plunges in, you can see the backup lights lit, which is impossible if the car was in drive.
Continuity mistake: As the Bandit says to Frog that "she's safer than in your mothers womb", there are no trucks behind the car. Then, a second later, he is in the convoy.
Factual error: The model of CB radio that Bandit uses is a Pace CB-166. There are three switches to the right of the microphone jack. The third one over is a PA (public address when switch is in the up position, think of a cop coming up behind you in traffic and radioing you to pull over on a loud speaker) and CB (citizens band when switch is in the down position, the setting you would have it set to to talk normally on the CB to others). In the cutaways where it shows Bandit messing with the radio, not only is the radio switched off each time (you can tell because the "TX" lights, meter, and channel selection is not lit, but the radio is switched to the "PA" setting (switch up). Bandit couldn't have used the radio normally when in this position.
Continuity mistake: In one shot near the beginning the bandit is being chased by the first of many cops, he comes to an intersection and turns left. But if you look close you can see that he actually turns the steering wheel to the right .
Answer: The trailer appeared in a recent episode of "The Walking Dead"
The trailer on the walking dead episode is a replica it's not the original one used in the movie as the one in TWD is a standard low slung with air baffles the original one doesn't have those and is also refrigerated.
