Code of Practice for off-road autonomous vehicles Oxbotica and the Transport Research Laboratory have piloted the use of a Code of Practice for the deployment of autonomous vehicles in off-highway environments, with a live trial conducted in a quarry using a number of off-road vehicles. The Code is available to download here The Code identifies the key elements for safe and efficient deployment of autonomous vehicles in off-road industries. Off-road environments can include mines, quarries, farms, refineries, warehouses, ports, and airports, feature more varied hazards and less structured scenarios than on-road settings with no universal highway rules, such as speed limits or junction etiquette.
