The Driver and Vehicle Licensing Agency records the driving licence holders who have entitlement to drive Heavy Goods Vehicles (HGVs) in Great Britain. It does not record those who are actually working as HGV drivers. In July 2014, 916,244 drivers had full HGV entitlement and 428,040 had provisional HGV entitlement, a total of 1,344,284.
The ONS Labour Force Survey showed that 285,000 people were working as heavy goods vehicle drivers in the United Kingdom in April – June 2014. However, other people will be driving heavy goods vehicles as part of their work in other sectors, such as retail or construction.
