Autonomous cars have become prominent over the years. As such, the industry has set standards for determining a vehicle's automation level to ensure road safety. These standards can also help owners identify their vehicle needs like required maintenance or car insurance policy coverage.

Level 0 (No Automation): The vehicle operates without autonomous capabilities at this level. Human drivers control all aspects of driving, such as steering, acceleration, and braking.

Level 1 (Driver Assistance): Level 1 vehicles feature systems that can assist the driver with specific functions, like adaptive cruise control or lane-keeping. However, the driver still primarily controls the car.

Level 2 (Partial Automation): These vehicles have advanced driver assistance systems (ADAS) that simultaneously control steering, acceleration, and braking under certain circumstances. However, the driver must remain attentive and always ready to take control.

Level 3 (Conditional Automation): Vehicles in this level can manage most driving tasks under specific conditions and environments. The driver is not required to monitor the road constantly but must be ready to take over when the system prompts their control.

Level 4 High Automation: Level 4 vehicles can perform all driving tasks and functions within a defined operational design domain (ODD). They can operate autonomously without driver intervention in certain conditions or areas, like predetermined geographic spaces or specific road types. However, they may still have limitations or require human control in complex situations.

Level 5 (Full Automation): This level represents the pinnacle of autonomous driving. Level 5 vehicles can operate autonomously in all conditions—eliminating human intervention. They can handle complex environments, unexpected events, and diverse road conditions without drivers controlling the car.


How Autonomous Cars Work
