ISO 17361:2017规定了车道偏离警告系统的系统定义、分类、功能、人机界面（HMI）和测试方法。这些车内系统可以在高速公路和类似高速公路的道路上警告驾驶员车道偏离。主体系统可利用光学、电磁、GPS或其他传感器技术，发出与可见车道标记一致的警告。在有临时或不规则车道标记的路段（如道路施工区）发布警告不在ISO 17361:2017的范围内。ISO 17361:2017适用于乘用车、商用车和公共汽车。 系统不会采取任何自动措施来防止可能的车道偏离。驾驶员仍需对车辆的安全运行负责。

ISO 17361:2017 specifies the definition of the system, classification, functions, human-machine interface (HMI) and test methods for lane departure warning systems. These are in-vehicle systems that can warn the driver of a lane departure on highways and highway-like roads. The subject system, which may utilize optical, electromagnetic, GPS or other sensor technologies, issues a warning consistent with the visible lane markings. The issuance of warnings at roadway sections having temporary or irregular lane markings (such as roadwork zones) is not within the scope of ISO 17361:2017. ISO 17361:2017 applies to passenger cars, commercial vehicles and buses. The system will not take any automatic action to prevent possible lane departures. Responsibility for the safe operation of the vehicle remains with the driver.
