Autonomous trucks generally officially operate at what's known as Level 2, an engineering standard that includes technologies such as automatic braking, acceleration, and some amount of steering. (Basic cruise control, by contrast, would amounts to Level 0, and certain features such as lane-assist or adaptive cruise control would be Level 1). However, autonomous trucks are often effectively operating at Level 4 – or "high automation," with their safety drivers generally only taking over on local roads.
