A commercial vehicle is any type of motor vehicle used for transporting goods or paying passengers. Depending on laws and designations, a commercial vehicle can be any broad type of motor vehicle used commercially or for business purposes.

A large goods vehicle (LGV), or heavy goods vehicle (HGV), in the European Union (EU) is any lorry with a gross combination mass (GCM) of over 3,500 kg (7,700 lb). Sub-category N2 is used for vehicles between 3,500 kg and 12,000 kg (26,000 lb) and N3 for all goods vehicles over 12,000 kg 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 3,500 and 7,500 kg which according to the EU are also "large goods vehicles."
