I suspect the sign is the same from the other side, yes.

One "problem" is that these are asymmetric. You can enter from East and drive West until the sign. But you (probably) cannot enter from West. So the access is directional.

Secondly, that's not just delivery, that's "service vehicles" ("pakalpojumu", whatever that legally means). Taginfo has plenty of `service` uses, so that's a thing (although I wonder if people mean like utility/municipal/repair service).

Also, you probably meant to do `motor_vehicle=delivery`[1]; I'm pretty sure `delivery` as a tag is not used like that because it would be ambiguous to mode of transport.

So it is probably `motor_vehicle=delivery;service` on the West small bit and `motor_vehicle:forward=delivery;service` on the East full section. The problem these are multiple values and consumers suck at those. But I have no idea how to tag it with exceptions or conditions or something.

P.S. Yeah, I know about the sign layer :) It does take a few days to a week or more to actually update, although this time it was fairly fast. I do indeed use it a bunch to find stuff like living zone borders. Although like 95% of footage is yours anyway, so there is rarely anything left to fix for obvious things.
