Understanding the 6 Levels of Self-Driving Cars: A Complete Guide
Self-driving cars are classified into 6 levels (0-5) by SAE International: Level 0 (No Automation), Level 1 (Driver Assistance), Level 2 (Partial Automation), Level 3 (Conditional Automation), Level 4 (High Automation), and Level 5 (Full Automation). Current consumer vehicles typically operate at Level 2, with some reaching Level 3 in specific conditions.
Evolution of Autonomous Vehicle Technology
The journey toward fully autonomous vehicles represents one of the most significant technological shifts in automotive history. As we progress through different levels of automation, each stage brings new capabilities and challenges that reshape our understanding of transportation.
Level 0: No Automation
While classified as having "no automation," modern Level 0 vehicles incorporate several important safety features:
- Basic Safety Systems:
