Narrative:

After pushback we were cleared to txwys D, south, and B to runway 25R. After passing 'chkpoint 2' we were reclred to txwys south, and B to runway 25R. On taxiway B there were steel plates, if you taxied slower you could drive around most of them. This is what I was doing. It was dark and the taxi light did not illuminate them very well. After we passed taxiway F, tower asked us why we did not hold short of taxiway F. We told him we were not instructed to. He told us that we were not instructed to by him, but there was a sign there. We asked him what he wanted us to do and he cleared us into position and hold. It is not standard procedure for us to go to runway 25R. Before we pushed I thought we would be given runway 25R at that time of the morning. I looked at the airport diagram and thought I read the signs as we were taxiing. I must have issued at least one. Supplemental information from acn 537193: I changed to tower frequency approaching taxiway F. Shortly thereafter, tower asked us why we didn't stop at taxiway F. Neither the captain nor myself heard any instructions to do so. Tower said there was a sign on the taxiway. We did not see that either (nighttime).
