Under an EU directive, member states must adopt and publish the necessary regulations by 26 November 2028, with application required only from 26 November 2029.

Motorhome manufacturers such as Robeta support raising the limit to 4.25 tonnes, which would provide 750 kg of additional payload capacity, but note that individual vehicle technical limits must still allow it.
