Level 3 Automated Vehicle

Limited Self-Driving Automation is the fourth level of the 5-level NHTSA vehicle classification system. Vehicles at this level of automation enable the driver to cede full control of all safety-critical functions under certain traffic or environmental conditions.

Vehicles at this level of automation enable the driver to cede full control of all safety-critical functions under certain traffic or environmental conditions and in those conditions to rely heavily on the vehicle to monitor for changes in those conditions requiring transition back to driver control. The driver is expected to be available for occasional control, but with sufficiently comfortable transition time. The Google car is an example of limited self-driving automation.
