A driverless delivery truck is being used on public roads in Sweden. The lorry, weighing 26 tonnes and known as a T-Pod, is being used alongside regular road users.
Moving goods between buildings on an industrial estate, the vehicle is not entirely autonomous. It requires a remote operator working behind the scenes in a control room.
Transport regulators in Sweden have imposed strict controls on the T-Pod. It has a top speed of 3mph (5km/h) and only makes journeys between two buildings on the industrial estate. Advanced communication systems ensure that the human operator never loses contact with the vehicle.
Fully autonomous vehicles are being tested and trialled in different countries around the world. Many of these trials involve specialised vehicles in locations such as airports.
Of course, the real test will be when driverless vehicles are regularly used on busier public roads.
