What Are Autonomous Driving Levels? [An Explanation for Children]

It is an international standard representing the stages of advancement in autonomous driving technology. It is divided into six levels, from Level 0 to Level 5.

• Level 0: Fully human-operated (no autonomous driving)
• Level 1: Some functions, such as the accelerator and brakes, are automated
• Level 2: Steering, acceleration, and deceleration are automated in coordination
• Level 3: Mostly autonomous driving, but control is handed to a human in specific situations
• Level 4: Fully autonomous driving in designated areas
• Level 5: Fully autonomous driving in all situations

Currently (2025), commercially available vehicles generally reach a maximum of around Level 2.
