DK company Kloster sometimes transport trailers stacked like this, although not deregistered ones.
Their flatbed trailers are used for transporing prefab concrete building elements to construction sites. Often the elements will be lifted off the trailer by crane and straight onto the building under construction. To avoid long waits, the truck driver can uncouple the trailer on the site, then go straight back to the element supplier with just the tractor unit and pick up another trailer. Meanwhile, another tractor can wait at the construction site until 3 trailers have been emptied, then stack them and take them back to the element supplier, ready for another round.
Regarding the trailers seen here, considering the location, I'd say with almost 100% certainty that they are being exported. That's often done like this, stacking as much as possible and only the vehicles in actual contact with the road having any kind of registration.
Quite often, the destination will not be actual new owners, but big trade hubs in Balkan countries. There are a few websites selling used trucks and trailers from all over Europe, usually going further east. Because they are always sold to customers in the south or east, they get transported to these huge hubs from all the source countries, to be closer to the customers.
Thank you for the info.
In fact, there are so many trucks that they exported to Asian territory, by using either non-standard plates of various countries like from Italy, Germany, etc. But most of the time, exported stuff have regular export plates issued on them. Either from Germany, or from other countries like Poland, Austria, Denmark, even from Lithuania and Latvia too. Most of my export spots are trucks with no trailer attached, and those trucks were Volvo FHs, DAF XF106 Facelifts, MAN TGX trucks, even Next Generation Scanias as well. However, Trucks can even show up with trailers behind. Either loaded with Truck cabins, or loaded with Trailer chassis stacked each other. Other exported stuff were the Panelvans and Boxvans. Even the smaller commercial vehicles too. Like Ford Transit Connect, Volkswagen Caddy, Mercedes-Benz Citan, etc. As for other commercial vehicles, mostly the MB Vitos, Sprinters and Ford Transits are get exported. Many were have Germany Export plates on them. Or can have Poland Red plate and even from NL with white plate.
Nonetheless, I don't know what else to explain about it further.
