Continuity mistake: When David drives away from the petrol station near the start of the film, you will see the truck catch up with him in the next scene. Take a look at Davids parcel shelf in his car when you see the truck fly round the bend, and you will notice a white baseball cap and a pair of sun glasses on it. They were not there before and also not there for the rest of the film. (00:14:20)
Revealing mistake: At the reptile farm, the phone booth Mann uses to try and call for help has no phone lines attached to it, above or below ground (you can see that there are no underground wires when the truck mows the booth down). It's definitely not a wireless/radio telephone, either. There should be lines running to it, but there are none. (00:57:00)
Continuity mistake: Towards the end of the movie where David begins to take advantage over the truck driver, and he turns on right towards the climb also breaking the cartels and fences, the weather changes in two shots: it's cloudy before and sunny immediately after.
Continuity mistake: After the truck tried to make David's car hit by the train dabbing it from behind, the car has a dent on the right rear light, but in a following scene, the dent has vanished. (00:53:09 - 00:54:30)
Continuity mistake: When David has the accident and crashes his car against the fences, he steps out of it and closes the door, but when he comes back to go on his own way, the car door is inexplicably open. (00:26:49 - 00:42:52)
Continuity mistake: Visible on the theatrical release. After David has overtaken the truck, you can see from the interior shot that David has his seat belt on. A few seconds later in the external shot David is no longer wearing his seat belt. (00:08:10)
Continuity mistake: When David returns on his way after sleeping, he first wears his glasses in a shot, but when he suddenly brakes after seeing the truck stopped on the side of the highway, his glasses are gone. (01:03:07)
