Stuck Up, Called Up, Stand Up

[anupumh]

Hi,

I am stuck up in traffic.

I called up John.

I am standing up on the roof of the building.

Are these constructions grammatically appropriate?
Do native speakers use them?

Thanks

I would say that the first example is not natural, we would say "I am stuck in traffic", the others are fine.

But then in all the 3 constructions, the usage of "UP" is useless..

Yes, you could say that.
