Lane Keeping technologies are designed to prevent you from leaving your lane of travel.
Lane keeping technologies have the potential to reduce the impact of run-off-road and head on crash types by 21-86%.
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.
