ISO 11270:2014 contains the basic control strategy, minimum functionality requirements, basic driver interface elements, minimum requirements for diagnostics and reaction to failure, and performance test procedures for Lane Keeping Assistance Systems (LKAS). LKAS provide support for safe lane keeping operations by drivers and do not perform automatic driving nor prevent possible lane departures. The responsibility for the safe operation of the vehicle always remains with the driver. LKAS is intended to operate on highways and equivalent roads. LKAS consist of means for recognizing the location of the vehicle inside its lane and means for influencing lateral vehicle movement. LKAS should react consistently with the driver expectations with respect to the visible lane markings. The support at roadway sections having temporary or irregular lane markings (such as roadwork zones) is not within the scope of ISO 11270:2014. ISO 11270:2014 is applicable to passenger cars, commercial vehicles, and buses.
