New or Imported trailers over 3,500kg Gross Design Vehicle Weight (GDVW) used for the carriage of goods are required to be registered at the Motor Tax Office.

A legal requirement to renew the trailer licence annually together with the submission of a valid Certificate of Roadworthiness (once the trailer has been licensed in this country for one year) for the trailer still applies even allowing for the fact that there is no fee required.

Heavy Goods Trailers which are designed to be towed exclusively by agricultural tractors and trailers which are designed and constructed exclusively for use by the Defence Forces, Civil Defence, Garda Síochána or Fire Services are exempt from the requirement to have a type approval certificate regardless of their date of manufacture.
