You must register commercial trailers over 750kg and all trailers over 3,500kg before towing them through some mainland European countries.
Trailers that have to be registered
From 28 March 2019, trailers must be registered before they can travel through countries that have ratified the 1968 Vienna Convention on Road Traffic.
You must register:
- commercial trailers over 750kg
- non-commercial trailers over 3,500kg
You can voluntarily register non-commercial trailers that weigh over 750kg, but there’s no legal requirement to do it.
This means that these trailers making international journeys will need to:
- display their own registration plate (separate from the vehicle towing them)
- be able to show the trailer registration certificate to a foreign authority on request

Trailers must be registered to travel in these countries in the EU, European Economic Area (EEA) and Europe:
Albania, Andorra, Armenia, Austria, Azerbaijan, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, Italy, Kazakhstan, Latvia, Lithuania, Luxembourg, Macedonia, Moldova, Monaco, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Russia, San Marino, Serbia, Slovakia, Slovenia, Sweden, Switzerland and Ukraine.

If the UK leaves the EU without a deal
If the UK leaves the EU without a deal on 31 October 2019, some EU and EEA countries may also require a separate Green Card as proof of insurance for trailers.
If you’re travelling with a trailer, contact your insurance provider to get 2 Green Cards - one for the towing vehicle, and one for the trailer.
This does not mean that you need to buy separate insurance.
