Lane keeping technologies are designed to prevent you from leaving your lane of travel.
Lane Departure Warning systems use cameras to detect line markings and warn you if you’re drifting out of lane. It will alert you via a sound, visual display or vibration that your car is about to veer out of your lane.
These systems are only a warning and you are still required to take action and steer back into the driving lane.
Lane Keep Assist is estimated to reduce run off road and head on crashes resulting in fatality or serious injury by 22%.
Lane keep assist technologies must be able to detect the lane markings or road edge to determine if the car is leaving or has left the lane. If there are no visible line markings the technology may be able to detect the edge of the road and continue to function.
Lane keeping systems will not function on gravel roads and in snowy conditions where there are no visible line markings or a distinct road edge.
