That's a strange statement. You don't have to be *told* that - it goes
without saying (unless its a multiple-track railway!)

So do you maintain that obeying warning signals should be at the
discretion of the road user?

There's no discrepancy in fact, just in the way you've put it.

Not a very sensible assumption. There are lots of factors involved in
safety, not just speed.

The implication of that statement would lead to more level crossing
accidents.

Could be both.

In the case in question, active warning systems may not have helped.
Boom barriers have been known to come down on slow moving vehicles.

That's incorrect. The timing of the activation of a level crossing
warning always has the primary aim of clearing of the track in time for
the train.

You can't seriously advocate that truck drivers independently dictate
the signalling of trains. What about having a system by which drivers
of long or heavy vehicles have to ascertain from train control whether
there is any potential danger before entering a level crossing?

Trains are even less likely to be on schedule if your suggestion above
was ever implemented!
