Lane Departure Warning

Lane departure warning alerts the driver when the car drifts out of its lane without indicating.

What is Lane Departure Warning?

It uses the front camera. Warnings are sounds, vibration or symbols. It does not steer. It is the simpler predecessor of lane keeping assist, which actively steers the car. The system usually works only above a certain speed, such as 60 km/h, and is suppressed when the driver indicates. Roadworks with temporary yellow lines can confuse some systems.

How it works

The camera detects lane markings.

Why it matters for your car

Faded markings reduce reliability. Keep the windscreen clean.
