A heavy goods vehicle (HGV), also large goods vehicle (LGV) or medium goods vehicle, is the European Union (EU) term for any truck with a gross combination mass (GCM) of over 3,500 kilograms (7,716 lb). Sub-category N2 is used for vehicles between 3,500 kilograms (7,716 lb) and 12,000 kilograms (26,455 lb) and N3 for all goods vehicles over 12,000 kilograms (26,455 lb) as defined in Directive 2001/116/EC. The term medium goods vehicle is used within parts of the UK government to refer to goods vehicles of between 3.5 and 7.5 tonnes which according to the EU are also 'large goods vehicles'.
Commercial carrier vehicles of up to 3,500 kilograms (7,716 lb) are referred to as Light commercial vehicles and come into category N1. Confusingly though, parts of the UK government refer to these as 'Light Goods Vehicles' (also abbreviated 'LGV'), with the term 'LGV' appearing on tax discs for these smaller vehicles. Tax discs use the term 'HGV' for vehicles over 3.5 tonnes.
HGVs must not exceed 40 tonnes laden weight or 18.75 metres (61.5 ft) in length to cross boundaries in the EU, but longer and heavier vehicles (LHVs) known as Gigaliner, EuroCombi, EcoLiner, innovative commercial vehicle, mega-truck, etc., typically 25.25 metres (82.8 ft) long and weighing up to 60 tonnes are used in some countries, and the implications of allowing them to cross borders was being considered.
It is necessary to have an appropriate European driving licence to drive a large goods vehicle in the European Union. There are four categories:
Drivers who passed a Category B (car) test before 1 January 1997, will have received Categories C1 and C1+E (Restriction Code 107: not more than 8,250 kilograms (18,188 lb)) through the Implied Rights issued by the Driver and Vehicle Licensing Agency (DVLA) (more commonly known as Grandfather Rights).
All UK LGV licence holders must undergo a strict medical examination and eye test on application, at age 45 and every 5 years thereafter. On reaching 65 years of age, a medical examination must be performed on an annual basis.
