How does the lane departure warning feature work in the Audi A1?

I've heard about the lane departure warning feature in the Audi A1 but I'm not sure how it actually works. Can someone explain it to me?

The lane departure warning feature uses sensors and cameras to detect the markings on the road. It then alerts you if you are drifting out of your lane without signaling.

I've found that the lane departure warning feature in the Audi A1 is a great tool for helping me stay focused and within my lane on long drives.

The lane departure warning feature can be adjusted to give either audible or visual alerts, depending on your preference. It's a handy feature to have, especially on busy highways.
