Continuity mistake: When Buford T Justice is chewing out the trooper on the road at the accident, there is one point when you can see that all the cars have passed. A pickup truck is heading toward them, no other vehicles. Then it cuts to another angle facing Buford, and you see the tail end of a tanker truck that was not in the previous shot.
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.
Factual error: When they are only 4 miles from the end, after Frog asks if the Bandit had been expecting all of what was going on, the Bandit picks up the mic, keys up, and calls for the Snowman. The Bandit does not let go of the key, yet you hear Snowman's reply. That is impossible. You need to let go of the key. Bandit then continues to talk on the radio.
Continuity mistake: During the final scene as they are heading down that two-lane blacktop to the fairgrounds, Reynolds and Reed have a conversation over the CB radio. In the wide shots, the two lane road curves around tree-covered hills. In the close-ups of Reynolds, you can see the interstate highway through the rear and side windows. No hills, no trees, no winding road.
Revealing mistake: When Frog says "We're going 110" she's misreading the speedometer. It shows that they're going 110 kilometers/hr, which is 70 miles/hr. Also, the ignition is turned off and the oil pressure and temperature gauges read far lower than they would if the car was actually going 70mph. There's also far too much dust on the dash and gauges for a brand new car that hasn't been on any dirt roads yet.
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.
Continuity mistake: After the first major chase of the film, where the police car ends up in the lake backwards, there is a shot of the Trans Am power-sliding around a dirt corner as it gets back on paved roads to continue on. During this shot, it is plain to see that the entire three-piece front spolier (from each front wheel and under the bumper) is completely missing, probably torn off by the uneven ground while shooting this sequence.The immediate next scene shows the entire spoiler back in place as if nothing happened.
Factual error: After the Bandit starts negotiating the challenge, he says that hauling beer east of the Texas state line is bootlegging. Actually, Texarkana is a city on the state line border of NE Texas and SW Arkansas. The city is divided in half on the main north/south street called State Line Blvd. The double yellow lines in the center separate Texarkana, Texas on the west side from Texarkana, Arkansas on the east side. Texarkana, Texas is located in Bowie County, Texas which is a dry county (meaning no alcohol sales or consumption except through/inside private membership in organized, officially recognized organizations, i.e. VFW, Rotary, Elks, etc. - transportation, or distribution of alcohol are allowed). Therefore, there would be no Coors distribution center in Texarkana, Texas. With that in mind, hauling beer east of the Texas state line from Texarkana, Texas to Texarkana, Arkansas is not bootlegging. Hauling beer west of the state line of Texarkana, Texas from Texarkana, Arkansas is not considered bootlegging if it is performed by a licensed driver working for a licensed brewery or distributor of a licensed brewery during that person's normal working responsibilities and duties of said employment (federal interstate trade). Other than that, it is bootlegging if a private individual buys alcohol in Texarkana, Arkansas and then transports said alcohol into Texarkana, Texas (which happens 1000's of times a day).
Continuity mistake: Sheriff Buford T Justice was supposed to be from Texas, but right as they start trying to find Frog (and before they caught up with Bandit), he passes an interstate sign with Georgia on it. If they were really in Georgia, that would have been one quick trip from Texarkana, and less than 60 miles to Atlanta.
Continuity mistake: At the end of the movie when Bandit, Frog, and Cledus are sitting in Big Enos' red Cadillac talking on the radio to Buford T Justice, a green Cadillac, which has been seen several times during the movie, is seen parked in the upper right portion of the screen. When Bandit pulls out on his way to Boston for clam chowder, Buford takes off chasing him and the green Cadillac is no longer there.
Continuity mistake: When the motorcycle patrolman is chasing the trams am with a patrolman in the car behind him, a second highway patrolman crosses the median to join the chase. When the car crosses the median, the left front tire blows out after the car slides onto the highway. In the following scene the car is in the chase with a perfectly good left front tire.
