In 2004, 1.4 million foreign registered heavy goods vehicles (HGVs) travelled to mainland Europe from Great Britain, while in 2005 the figure was 1.5 million vehicles. It is not possible to provide a UK estimate since information on foreign vehicles leaving Northern Ireland via the Irish Land Boundary is not available.
The Department for Transport estimated that in 2003, the last year for which figures are available, foreign registered HGVs travelled 0.9 billion kilometres in Great Britain.
