UK hauliers and drivers who operate in the EU will need new documents if the UK leaves the EU without a deal on 31 October 2019.
GOV.UK have produced a pocket guide giving advice to hauliers and commercial drivers on the process flow and process to move goods through roll-on, roll-off locations (RORO).
The guidance covers moving goods (imports and exports) from the EU to UK and the Uk to EU in a no-deal Brexit (excluding Northern Ireland).
There is further information available via GOV.UK on this subject.
