All Eco-Trailer Car Trailers are built in conformity with European Whole Vehicle Type Approval (ECWVTA). It is European law that any manufacturer of trailers must have this accreditation. We are recognised by RDW in The Netherlands and our workshop systems, quality control, product control and design are audited and monitored in line with ECWVTA. This allows our trailers which are all supplied with an EC Certificate of Conformity to be registered in any EC member state. If you wish to do this then please contact either ourselves or the Eco-Trailer distributer in that country to assist with the registration procedure.
