A drowsiness sign notification system applied to a vehicle includes a driver monitor and a controller. The driver monitor detects a driver state being a state of a driver of the vehicle. The controller executes a drowsiness sign determination process that determines whether or not the driver shows a drowsiness sign based on the driver state. When it is determined that the driver shows the drowsiness sign, the controller executes a first drowsiness sign notification process that gives a first drowsiness sign notice to the driver through display or vibration without using audio. When it is determined again that the driver shows the drowsiness sign after the first drowsiness sign notification process, the controller executes a second drowsiness sign notification process that gives a second drowsiness sign notice to the driver through audio.
