Crossbuck sign
Marks the railroad crossing itself. Yield to any train and never stop on the tracks.
How to recognise it
This sign is a white X shaped crossbuck in white, the standard background for a rule you must obey. A round yellow advance warning, then the white crossbuck at the tracks themselves. The crossbuck has the legal force of a yield sign, which surprises a lot of test takers.
What the test wants you to know
The crossbuck has the legal force of a yield sign. A great many test takers get this wrong by treating it as a decoration rather than a control device.
The sign people confuse it with
Crossbuck gets mixed up with Railroad Crossing Ahead more than any other pairing in this category. Put them side by side and the difference is obvious, which is exactly why it is worth doing once rather than meeting them cold in the exam.

Reading about a sign is not the same as recognising it in half a second with an examiner watching. Every state road signs test on this site shows the sign and asks you to name it, then shows four faces and asks you to pick the right one.
