Continuity mistake: Sheriff Buford T. Justice gets out of his car and leaves the door open. A few moments later, we see a different shot of the car with the door closed. Then a truck drives by and tears the car door off which is open again.
Continuity mistake: When the Bandit first pulls over and picks up Sally Field, then he screeches off, if you look at the road you can see all the skid marks from all of the other takes of this scene, even down to the bit where the van pulls out of the junction and the bandit does his thing and then suddenly speeds off.
Continuity mistake: In the scene near the end Snowman drives a truck into a load of police cars if you play it in slow motion you can see a protector around the lights.
Continuity mistake: When Bandit and Snowman are picking up the beer, Bandit crashes the forklift into the boxes of beer which also forces Snowman to fall into the boxes. You can see all of the boxes crumble under the weight of Snowman, which then shows that all of the boxes are empty.
Continuity mistake: When the Bandit and Frog make the jump onto the field where the kids are playing football, the Trans Am goes through a chain linked fence then under a score stand. As it emerges through the wall, the antenna is broken, lying rearward onto the rear glass. The very next shot from the other side shows the antenna is fine and a few wood boards are around it. And when the boards fall off, this antenna falls off completely. The next time we see the car, a third antenna is in place again.
Continuity mistake: In the scene where Frog and Bandit crash onto the football field, as they are getting off of the field, you can see them approaching a dugout made of concrete blocks. When they crash through to the other side, the same building is made of wood.
Continuity mistake: In the scene where the tractor trailer and the Trans Am meet up at Ole Miss, We see the Trans Am stop a ways ahead of the rig. In the next shot the Trans Am is closer than before.
Revealing mistake: In a scene where Frog is riding with the Bandit, she's resting her head on the center gearshift console. Although they're supposed to be cruising down the road, the automatic transmission shifter is in neutral.
Continuity mistake: When The Bandit is getting ready to get in the convoy of trucks, right before he gets in between the trucks, all the trucks are close together. When they show a closeup inside the car, you can see the trucks are farther apart when you look out he back window. In the next shot when the cop car is pulling up, the trucks are close to each other once again.
Continuity mistake: The odometer in the Trans Am is shown to have 1108.8 miles on it, rolling on up to 1108.9 during the shot. A little later during the movie, after they have travelled a considerable amount of miles, Bandit says, "We'll let's just see what he's got under the hood." A close-up of the speedometer shows the speed increasing to about 120 Km/hr, but the odometer is still on 1108.9, and counting.
Other mistake: Many times, especially early on, you can hear shifts and see through skid marks that the Trans Am is a 4-speed, but interior shots show it to be an automatic transmission.
Revealing mistake: In the scene where the Trans Am is hiding among the truck convoy, you can see that the vehicles are all on the wrong side of the highway, as if to let the camera vehicle travel on the normal side of the highway. Notice the missing westbound lanes in the background as the vehicles are pointing directly to the viewer's right...then the lanes are back when the vehicles are shown from the front or rear.
Revealing mistake: When Frog makes her "We're going 110." comment, they then show a close-up of the dash-board. Even though the speedometer does show them to be going 110 kilometers/hr, the ignition key is in the 'off' position, and the 'amp' gauge shows '0'. This is a clear indication that the engine was not actually running during this shot.
Continuity mistake: After the Bandit jumps the bridge Sheriff Justice rear-ends the cop car in front of him, smashing the hood of his car. In the next scene Sheriff Justice's hood is fine.
Continuity mistake: When the Bandit first drives the Trans Am out of the trailer, the front license plate is easily seen, and it has a Georgia state flag on it. When Bandit wipes out the row of mailboxes along the side of the highway, the license plate is upside-down.
Visible crew/equipment: When Snowman is pulled over by "Mr. Evil Knievel" (the cop) two lighting reflections can be seen in his helmet.
