In the situation presented, does the visible sign warn you of driving through tram tracks?

In the video you are driving along a street in a city next to a noise barrier, and on the left a silver van is travelling in the same direction; on the right there is a yellow triangle with a tram symbol - sign A-21 "tram" - and under it plate T-7 showing how the tracks cross the road. The sign warns of a place where the road crosses tram tracks. The answer is: yes.

The Regulation on road signs and signals states that sign A-21 "tram" warns of a place where the road crosses tram tracks, and plate T-7 placed under it shows the layout of the tracks and the road at this crossing - here the tracks run diagonally, so you cross them at an angle. Warning signs require you to exercise particular caution, and in this place it is especially important: the Road Traffic Act gives a rail vehicle right of way over other vehicles regardless of the side it is coming from, and a tram weighs several dozen tonnes and needs much longer to brake than a car. As you approach the tracks, you slow down and look both ways along the tram tracks, and you drive across the diagonal, wet rails without turning or braking on them, because they are as slippery as ice.
