Which statement describes Level 3 automation?

• A. Driver does everything
• B. System drives with no driver input
• C. System provides advisory information
• D. System does most work but you can take over

Answer: (D)

Level 3 automation is conditional automation: the system can handle most driving tasks in certain situations, but the human driver must stay engaged and be ready to take over when the system requests or when its limitations are reached. The statement that describes the system doing most of the work but you can take over matches this setup exactly—the system handles driving most of the time, yet you can intervene if needed. The other descriptions point to different levels: a driver doing everything is fully manual; a system driving with no driver input is higher automation; and system advisory information implies no active driving control.
