The utility model relates to a driver fatigue warning device, especially relates to an infrared distance sensor installed in the microcomputer controlled by the driver behind the head, by detecting the driver between the head and the sensor in the regular sitting under distance if there is a non normal increase or offset, in order to determine whether the driver is fatigue driving state, if it is then, the output sound and light signals to remind the driver to restore normal driving posture.
