The Society of Automotive Engineering Standard J3016 defines five levels of driving automation. Levels zero, one and two of driving automation contain driver support features designed to aide a person while driving, but the person must constantly supervise the features and the vehicle to maintain safety. Levels three and four of driving automation contain automated driving features designed to drive the vehicle when certain conditions are met. Level five of driving automation contains automated driving features that can drive the vehicle under all conditions (SAE Standard J3016).
manufacturer is a person who either: 1) manufactures or assembles new
2) manufactures or installs special equipment on a previously-assembled truck that forms an integral part of the new vehicle.
