Operator licensing is necessary for the operator of any goods vehicles over 3.5 tonne GVW which are used in connection with a trade or business. The types of business entity – solo trader, partnership, limited company etc – is irrelevant; all businesses using goods vehicles are subject. Neither does it matter what the business is; almost all commercial activity necessitating the use of goods vehicles is covered, from supermarkets to builders, road hauliers to oil companies. Operator licensing still applies even when the operation of goods vehicles is incidental to the main business activity. Only people using goods vehicles entirely for private purposes are excluded.
