Continuity mistake: When Kevin vomits, it shows the vomit on the windshield; a few seconds later Nick is trying to use the windshield wipers to clean it off. The next couple of frames show us a clean windshield and this is before they even pull over to clean the window.
Plot hole: Near the end, when Ice asks to say goodbye to the kids in the hotel room, the kids have on their pajamas, yet their luggage was left on the train earlier in the day. It is unlikely that they would have gone to the train station to get their belongings following the chaos of the Christmas party.
Continuity mistake: When Ice cube is fighting with the trucker, he and the trucker roll down a slope. In one scene they are already down the slope but then the scene changes and they are now in the middle.
Continuity mistake: After the truckers attack the navigator, Nick throws his hat down, but a second later it is back on his head.
Continuity mistake: When Ice Cube is on the train, and the kids have gotten off, he is running inside the train to keep along side of the kids standing on the outside. As the train speeds up, just before he jumps off, the camera looks back at the kids and they are standing right at the end of the line (dead end) stop. So the train would have been coming from where there was no track.
Continuity mistake: When Nick's Navigator is being pushed against the rail on the highway, the rear view mirror is missing and in the next shot of the rear view mirror, it is obviously back. (00:45:45 - 00:46:15)
Factual error: At what is supposed to be the Portland, Oregon station, the train cars and conductor's hat are prominently labeled for a Canadian railroad. Passenger trains from Canada do not travel as far south as Portland.
Visible crew/equipment: During the wide shots of the freight train, special brackets are prominently visible underneath the door of the box car in which Ice Cube and the kids were riding. None of the otherwise identical boxcars have these brackets, which were probably used to support a removable camera during the close-up action scenes.
Factual error: Even though the signs have been changed to make the stand-in airport look like Portland, Oregon, an overhead sign at the curb still lists departures for Air Pacific, Aloha and HMY Airways. None of these airlines fly to Portland.
Continuity mistake: When Nick snatches Kevin's juice, some of it gets on Nick's face and begins to run down his cheek. However, in the next shot, the juice is gone. Nick's hands are visible throughout the scene, so he couldn't have wiped it off.
Continuity mistake: When Nick leaves the dealership in his new Navigator, the car sticker in the driver-side back window changes from being centered to being much lower by the time he parks in front of his business.
