A truck without a cab or driver is now being tested on a public road in Sweden, mixing with other traffic as it moves goods around an industrial zone.
Swedish startup Einride began operating the electric truck on a short stretch of road in the heart of Scandinavia.
Einride said the trial, which is due to run until the end of 2020, is the first time a fully self-driving truck without a backup driver has been allowed on a public road.
The truck can reach speeds of up to 85 kilometers per hour (53 miles per hour), but is only allowed to drive at 5 kilometers per hour (3 miles per hour) during the trial. The speed limit was set by the Swedish Transport Agency.
