Continuity mistake: The two Smokeys that join the chase with Evel Kneivel keep changing between Pontiacs and Plymouths throughout the scene. (01:21:45)
Continuity mistake: When Sally Field is driving the T/A, right after the Buford's car goes under the rig you can see that her door is locked. Right after the Bandit says, "I'm still trying to get rid of that Texas County Mounty," and the camera is on her, you can see the door lock is open. (00:46:05)
Factual error: When The Silver Tongued Devil contacts Bandit for a smokey report, he asks if the Bandit is "coming up on Fayetteville, on Interstate 82." Aside from the fact that Fayetteville, Arkansas is far off the direct route from Texarkana to Atlanta, Interstate 82 is about 1900 miles away from Fayetteville, in Washington state. In fact, at the time, there was no interstate highway at all near Fayetteville, Arkansas.DavidCBohn
Audio problem: The section of sound effects used as the Trans-Am and the big-rig pull up to the warehouse to get the beer is exactly the same 'loop' as the effects used when the Trans-Am and the big-rig stop by the pond to give 'Fred' his burgers for lunch. Specifically, the Trans-Am's engine idling down to a stop, then the T/A's door closing, then the big-rig's air brakes squealing a very distinctive sound and finally the big-rig's engine rattling to a stop. Exact same 'loop' both times.
Continuity mistake: The blue lights on Sheriff Justice's car are seen on and then off in the same scene several times throughout the movie during the action chase scenes.
Continuity mistake: When Bandit decides to turn himself in, and Snowman objects, you can see that Jerry Reed is wearing gloves. However, when they are entering the fairgrounds, and they show the entry through the windshield from the back of the cab, the person driving the tractor is not wearing gloves.
Continuity mistake: At the roadblock set up in front of the General Store (where Bandit asks Frog if she's ready), all three police cars are Plymouths. When one backs into another, a close-up insert shot shows the ramming car is a Pontiac and the rammed car is a 1960s-era Ford sedan. The next shot has two Plymouths falling into the roadside ditch. The accident itself is also impossible because just before the impact, you see the first car stop before it gets behind the car that will ram it in the next shot, avoiding the accident all together. (00:57:00)
Visible crew/equipment: All throughout the movie lighting reflections can be seen in Buford T. Justice's sunglasses.
Factual error: After the scene where Snowman is trying to leave a written note for the beer warehouse staff (and then throws his notepad away), Bandit's CB radio is shown receiving a signal and Bandit changing the channel, however, the radio is not powered on as the signal meter needle does not swing out, nor are the signal meter light, channel indicator light or receiving LED (yellow on this radio model) illuminated. (00:18:00)
Continuity mistake: In one scene Buford T. Justice comes up on a long line of cars stopped on the highway due to an accident, so he proceeds to pass the line of cars on the right berm of the road. He pulls up alongside a green Cadillac at the front of the line and stops just as a local cop walks up to his car. The shot changes to the passenger side of the car, but the green Cadillac is nowhere in sight when it was there just one second earlier. If the line had began to move there wouldn't have been enough time for the Cadillac to get out of the shot from a dead stop.
Visible crew/equipment: When Buford T. Justice is telling off the young officer when he is pulled over for driving his "evidence", as Buford heads back to his car a light and two crew-members are reflected in the back of his car.
Character mistake: In the scene where the Bandit convinces Snowman to go with him to Texarkana, Texas, to get the beer, he says, "It's only 900 miles there and 900 miles back." In fact, it is only 557 miles between Texarkana and Atlanta, meaning they could cover the 1114-mile round trip in the pre-determined 28 hours in an average speed of 40 mph.
