I've tried to translate it with Google, don't know if that's correct:

It is a Leopard 1 tank with a combat weight of 42 tons that landed on its head in the ditch along Viborgvej a little east of Skave on Friday.

Along with the tank - and also upside down - is the truck with trailer that should have transported the tank from Holstebro Kaserne to Aalborg.

The tank belongs to Aalborg Kaserner's Veteran Armored and Vehicle Association and has been in Holstebro, where it has been used for instructor training by Ukrainians.

On the way back to Aalborg, the truck was caught in a soft slope, and therefore Friday's working day has become quite a bit longer for Jens Martin Deitz, who is chairman of the Aalborg Barracks Veteran Armored and Vehicle Association.

We will start salvaging the tank at 10pm tonight, and then it will be shipped home to Aalborg, he says.

A mission he expects will take a few hours, during which Viborgvej will be closed at both ends. It will therefore not be possible for curious people to follow the rescue on site either.

The plan is for the truck and tank to be pulled apart first. Next, the truck must first be tipped around, and then the tank must be lifted onto a new semi-trailer.

There will be two recovery vehicles and a crane that will do the heavy work.

Due to the clean-up work, the Road Directorate is already calling for the speed limit to be reduced on Viborgvej east of Skave.

Also, there is another article providing an actual explanation of what happened:

A 42-tonne heavy tank is together with a truck and tows the land upside down east of Skave.

It happened on Friday morning during a transport from Holstebro Barracks to Aalborg.

TV MIDTVEST's reporter on the scene has spoken to the driver of the truck, who says that he was driving at 60 km/h when he pulled to the side on Viborgvej to make way for an overtaking truck.

In this connection, a set of wheels was caught by the very soft slope, and the trailer dragged further and further into the ditch, says the driver, who is very affected by the incident.

The encounter with the very soft rebate caused both tank, trailer and truck to topple over.

The driver says that he is safe after the accident.

I'd say, when 42 tonnes are pulling you back wanting to roll you over in the process, it appears you can only do so much. It's good that the driver is not injured, at least
