I don't know the situation in Italy, but I strongly disagree with the use of this particular sign. In my opinion, the sign reads like this: 3 lanes going forward, 2 lanes going to the "Zentrum", 1 lane to Budapest, exactly under the place where the panel is placed (which is not the case). Imagine I want to go to "Zentrum". The sign tells me to keep in the third lane, because the 2nd and the 3rd lane go there.
I faced this problem many times, especially in the vanilla map. There you would often see junctions of a 2-lane highway with one lane going right and one going forward, and this sign:

This tells me that there are 2 lanes going forward, with one going right that splits from the first lane. Staying in the first lane means that you can choose to go forward or go right. But we all faced the unpleasant surprise that the first lane suddenly turns right.
The previously mentioned sign, however, could be used in our situation (in part). You should keep the three lanes going forward on the left, and a panel similar to this on the right. It would mean that there are 2 lanes going towards Zentrum, with an additional one splitting to Budapest from the lane on the right. This way, the directions are extremely clear. The sign tells me that there are 5 lanes to choose from, and where to position myself to get where.
There should be an additional panel after this place showing exactly where the lane to Budapest begins. Something like this:

or even

Another way would be to remove the arrow from the panel towards Budapest. It will just tell the driver "there will soon be a way towards Budapest on the right". Again, there must be a sign showing exactly where the lane to Budapest begins. However, I wouldn't recommend this option, because you said the lane begins immediately after this split.
I can go further into detail about these signs, but I hope you understand why I don't like it and why it is incorrect. I haven't yet come across a place in real life where the sign lies to you about the direction of the lane you are in (which your sign does about the 3rd lane from the right). If you watch carefully, in the picture showing this place in real life, the signs are right (5 total lanes, 3 forward, one Zentrum, one Budapest... it is slightly different there, the two separate directions to the right don't split in the same place from the main road like in the in-game version).
If I don't rely on the arrows, then what will tell me where to position the truck? Far left for forward or far right for right is quite......
Also, @KrysEmlyn , in the rebuilt parts of Germany I have to say they did a great job with the signs. I haven't found any problematic situation like this one. Perhaps you can point out a place like this...
I find this issue one of the most disturbing problems that should be addressed. I hope you will reconsider the signage in that area
If I was unclear at some points, I would be happy to explain it further.
