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.Hawk
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.
