The purpose of the present invention is to manage an available exit gate for each vehicle exiting a parking lot. A vehicle exit management system having a gate terminal (161) for controlling an exit gate of a parking lot, a data communication module (DCM) (141), and a vehicle management server (110) which is connected to the DCM (141) via a network (170), is characterized by being configured suchthat the DCM (141) transmits priority information, which is acquired from the vehicle management server (110) on the basis of a user ID of an occupant of a vehicle (130), to the gate terminal (161) when exiting the parking lot, and the gate terminal (161) opens the exit gate when the received priority information satisfies a condition.
