Note I said “road checks” as in arriving by car. They totally closed the border and stop basically all non-Danish license plates for inspection. They are only supposed to be able to do this for emergencies for a max of 6 months. Instead, every 6 months they declare a new “emergency” so they can keep it closed indefinitely.

Can't speak for Denmark. But usually those border-checks are done couple km/miles after the border. Police will just stop "random" cars/trucks and do a "routine check".

And "random" it might be as much as 50% of the passing cars.
