Large Goods Vehicle (LGV) is the new formal term in the United Kingdom for goods vehicles (i.e. lorries) with a maximum allowed mass (MAM) over 3.5 tonnes. The former term Heavy Goods Vehicle (HGV) is, however, still very commonly used. The term was changed from HGV to LGV as not all countries in Europe had a word for heavy.
The LGV driver_s licence is divided into three categories. Category C1 (Class 3) allows holders to drive rigid vehicles up to 7.5 tonnes and C (Class 2) allows you to drive lorries over the 7.5 tonne limit. Category C+E (Class 1) allows the holder to drive articulated lorries and lorries towing a trailer over 750 Kg. Drivers passing their Category B (Car) test before 1st Jan 1997 are already en_title_d to drive category C1 vehicles.
