1. A system for preventing drunk driving of a vehicle, comprising:
a breath test device configured to detect carbon dioxide and alcohol content in a driver's breath when the driver performs breath authentication;
an alcohol detection unit configured to detect the driver's inebriation through the breath test device;
a computation unit configured, when the alcohol detection unit detects that the driver is in a drunk state, to compute a driving-possible time at which the driver's drunk state is resolved in the future so that driving is possible for the driver; and
a notification unit configured to output the driving-possible time or whether driving is possible for the driver through an infotainment system of the vehicle or the driver's terminal,
wherein the notification unit is configured to set the driving-possible time based on location information of the driver detected through a function of a GPS provided in the driver's terminal.
