When pulling up to a railroad crossing you have a few things going through your head about what you need to do and what you need to look out for! The first thing is obviously look around to see if a train is coming or is even in the near distance because getting hit by one of these can prove to be fatal.
The second thing you need to look out for is if the rail road crossing signs are coming down and if the lights are flashing warning everyone about the train nearby. The driver of this truck is doing none of these things and seems to be paying zero attention to what is going on around him.
The word that comes to mind here is situational awareness, the driver of the truck either had zero situational awareness or he actually thought his truck was fast enough to outrun the speeding train!
