With technology that monitors ordinary road markings, Active Lane Keeping Assist helps detect unintended drifting off-course, and alerts the driver by vibrating the steering wheel. If the driver continues to drift, it can selectively brake individual wheels to help guide the car back into its lane. New enhancements to the system help it to further detect and alert the driver to overtaking vehicles, vehicles you would need to overtake if you change lanes, and even oncoming traffic in the adjacent lane.
