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.
Continuity mistake: Just after Justice slams his patrol car into the beam in the street you see his head pop up with sunglasses on, an instant later they are off.
Continuity mistake: When Sheriff Justice is talking to the 3 boys there is a scenic view of the road and it appears dry. However when he leaves in the car minutes later the same road has several puddles of water.
Continuity mistake: At the beginning when big and little Enos Burdette show up at the truck races to see Bandit, a KW W925 is racing a GMC Astro 95. They cut away and then back, but this time the KW (still in the same lane) is racing a white cabover. The GMC he was racing in the earlier shot is now behind them getting ready to race a Chevy Titan cabover.
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.
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 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.
