You are using your motor vehicle’s lane keep assist system while driving. The system does not respond when you depart from the lane. What could be the cause of this?

The lane keep assist system relies on clear lane markings and good visibility to detect lane boundaries accurately. If the road is poorly illuminated, the system may not see the lanes well enough to function correctly. Heavy precipitation like rain or snow can obscure the camera’s view or lane markings, causing the system to fail. Additionally, if lane markings are missing or faded, the system cannot identify the lanes to provide assistance. These conditions interfere with the sensors and cameras that the system uses, so the assist may not activate or respond properly in these situations. Understanding this helps you recognize when technology may not be fully reliable and when you need to take extra care yourself while driving.
