Under what conditions can an active lane change assist system perform a lane change?

The selected combination correctly highlights the conditions necessary for an active lane change assist system to perform a lane change. According to German traffic regulations, the system must detect an adequately marked carriageway with multiple lanes, ensuring that the vehicle is in a suitable environment for a lane change. Additionally, it is critical that the system has not detected any vehicles in the relevant safety zone, which ensures that the lane change can be executed safely without the risk of collision.

However, one key consideration not included in your response is the detection of a sufficiently large gap in oncoming traffic. This is vital because, without a safe distance from oncoming vehicles, the lane change could pose a danger. In essence, all three conditions work together to ensure the lane change is executed safely and in accordance with traffic laws, prioritizing safety and proper traffic flow. Understanding these regulations helps ensure that drivers and their vehicles operate responsibly on the road.
