That's not my truck, it's a AI driver and he got first hit at full speed by a train coming from the right side, pushing it into the ground (result shown in one of the other picture in my screenshots).
The second train you can see here, was stopping where its first wagon is now, but the step by step driving into the crossing and then passing by.
The lights are flashing and there's also a warning signal audible.
I'm guessing the barriers didn't close because the AI had to break down on the rails because of a red traffic light at the end of this road leading into a small backlog.

I've just started a new profile and i was on my way to the internatinonal truck dealer at Flagstaff. It happened right after the highway exit at the railroad crossing, straight on the street leading to that truck dealer

that is a serious bug. #1,,,the crossing guards are not flashing and not down. #2 truck stuck in ground. It is hard for it to move out of the way. I hope you report this. Where was this?
