Abstract: A curfew violation notification method includes inputting a destination to a navigation system of a vehicle, detecting a plurality of routes from a current location of the vehicle to the destination, calculating an estimated time of arrival (ETA) of each route, determining whether the ETA of a first route selected among the plurality of routes is within a preset curfew period, and sending a notification message to a preset device if the ETA of the first route is within the curfew period. Accordingly, a driver may preliminarily recognize curfew violation to occur while driving, sudden curfew violation notifications while driving may be effectively reduced, and the possibility of distraction may be reduced.
