Safe driving evaluation systems, methods, and programs acquire traffic signal information that indicates the display status of a traffic signal present ahead in the traveling direction of a vehicle, determine the vehicle is within a prescribed stop supplement zone set up in front of the traffic signal installation point, and determine a red light encounter, which is a state where the vehicle is within the stop supplement zone and the traffic signal information indicates that the traffic signal is red. The systems, methods, and programs perform a stop supplementary operation with respect to a driver in order to stop the vehicle at the traffic signal installation point based on a driving operation of the vehicle during the red light encounter, and calculate a stop supplement percentage.
