Roll-on, roll-off international freight
Roll-on, roll-off international freight statistics provides information on all the main ferry routes between Great Britain and Europe, and the Channel Tunnel. It is based on information supplied by ferry operators and Eurotunnel.
Information about maritime, rail and air freight activity can be found in the appropriate sections of the transport statistics website.
In 2014, following changes to the data capture and processing systems used in the production of road freight statistics, the DfT Head of Profession for Statistics wrote to the UK Statistics Authority in September 2014 to request the suspension of national statistics status for road freight statistics. The response from the UK Statistics Authority is available.
Road freight underwent re-assessment in July 2016 and the national statistics status was reinstated in December.
