Continuity mistake: At the start of the film when Tom is doing his trial run, he is forced off the road to avoid crashing into two oncoming trucks, driven by Johnny and Red. His truck has the number thirteen number board on the front, which isn't on it during any other time during the trial run, although it's on the truck for the rest of the film.
Continuity mistake: When Tom accepts the job as a truck driver, he is given the logbook to the truck he is going to drive - registration number 321EMY. At the quarry, when he reverses towards Red's truck, the reg number has changed to 845DMX, the same as Red's truck. But when Tom gets back on the road his truck has changed back to 321EMY.
Continuity mistake: In the final chase sequence, when Tom takes number one truck, its registration number is 845DMX and it has a broken headlight. When Tom drives over a bridge the reg number has changed to 322EMY, but when he reaches the quarry the reg number is back to 845DMX and the broken headlight has been repaired.
Trivia: When we first see Red in the cafe as he walks over to the table, if you look on the cafe wall there is a poster for a play, "I Have Been Here Before" at the Royalty Theatre starring Wilfrid Lawson. Lawson appears in Hell Drivers as Ed.
