Lane Departure Warning
How this technology works
Lane Departure Warning systems detect markings in the road and warn a driver if he or she unintentionally leaves their lane without using the turn signal. Most systems use a forward facing camera mounted inside the windscreen by the rear view mirror. When the system finds that the vehicle is leaving its lane without a turn signal, it warns the driver with a warning light on the dashboard or a warning sound. Some systems vibrate the steering wheel or the driver's seat on the side the car is drifting.
- These systems may only operate over limited speed ranges. Most operate at speeds over 60 km/hr.
- Warnings stop if the driver turns on the turn signal.
Things for drivers to keep in mind
- The warning system reacts when a vehicle appears to be drifting out of its lane.
- This is a warning system only.
- A lane departure warning systems does not take control of your vehicle or prevent you from driving.
- These systems do not work without clear lane markings, on curvy roads, or in inclement weather
- Drivers are encouraged to read the owner's manual to become familiar with the system and the conditions when system operation is different or is not guaranteed.
As a car drifts off to the shoulder of the road, the driver is notified by an alert sound and graphic displayed on the dash.
