Not arguing with the regulations, just pointing out that based on airport diagram[1], since the truck was crossing rwy on taxiway D, the CRJ was on the right approaching from behind. I have never been inside an airport firetruck, but I guess from the driver's seat the jet would be quite hard to see in this case.

That is a good point but it seems instructions for ground vehicles seem to really stress this. For example this one: https://skybrary.aero/sites/default/files/bookshelf/1003.pdf

Says at pag 9:

"While driving on an aerodrome : Clear left, ahead, above and right

Scan the full length of the runway and the approaches for possible landing aircraft before entering or crossing any runway, even if you have received a clearance."

They have mostly glass cabs for exactly that reason. Only thing that would block your view is a passenger in the right seat.

Visibility was bad (night and mist) too.

But if your truck has blind spots and vis is poor, you shouldn't be driving as fast if at all.

		He was stopped until he received instructions to cross the runway from the person whose job it is to sit in a position with good visibility and tell people when they can cross runways. He wasn’t driving fast at all. The whole system is set up so that vehicles with blind spots (every large passenger jet) can safely move. We can’t say that emergency vehicles should just stay in on dark and stormy nights.
