Level 4 Automation refers to a high degree of automation in vehicles, where the system can perform all driving tasks in specific conditions without human intervention. This means that the vehicle can handle various driving scenarios, such as navigating through city traffic or highway driving, as long as it operates within its designated environment. In Level 4, the driver is not required to take control of the vehicle, but the system may have limitations based on geography or weather conditions. This level of automation is part of the SAE International classification system, which defines different levels of driving automation from 0 to 5.
