Which cars have a driver monitoring system?

Currently, models equipped with Driver Monitoring Systems (DMS) are primarily found in mid-to-high-end vehicles featuring intelligent driving assistance technology. These systems utilize cameras or infrared sensors to monitor the driver's facial features, eye movements, and head posture in real time, detecting hazardous conditions such as drowsy driving and distracted behaviors (e.g., using a mobile phone or smoking), and triggering audiovisual alerts to enhance road safety. For instance, certain locally assembled Japanese and German brand models have incorporated DMS functionality, typically operating in conjunction with L2-level driver assistance systems like lane keeping and adaptive cruise control. Some commercial fleet management solutions (such as Tenshi Technology's ES06 terminal) also achieve similar capabilities through external devices. As autonomous driving technology advances, DMS will become more deeply embedded in vehicle safety architectures, serving as a critical component in accident prevention.
