Continuity mistake: In the final scene when the squad car passes the zebra crossing Julie is working on, there are no vehicles behind the squad car, but in the next shot of Julie on the crossing a lot of cars have suddenly appeared.
Continuity mistake: Julie Kingdom and Mike Seton are on the motorbike riding in the country lane. Julie drops the map, they stop further on down the lane, but when Julie gets off the bike to pick the map up, it is in the lane right behind them.
Factual error: The squad are following the stolen lorry when it suddenly reverses across the road, causing the squad to swerve up the kerb, ripping a front wheel off the squad car. Four hours later when the body of the murdered lorry driver is found, Regan and Carter arrive at the murder scene in the same squad car. It would take more than four hours to recover the car and repair that much damage.
