12. A drunk driving preventing apparatus installed on a vehicle and including an alcohol sensor, comprising:
-
a test determining unit which determines whether or not to perform a test for detecting alcohol by the alcohol sensor, based on a predetermined condition, when the vehicle is started; a test performing unit which performs the test by the alcohol sensor when the test determining unit determines to perform the test; a control unit which disables driving operation of the vehicle when the test performing unit performs the test and alcohol is detected as a result of the test; a specific time storing unit which stores a specific time; and a present time obtaining unit which obtains a present time, wherein the test determining unit determines whether or not to perform the test based on the present time obtained by the present time obtaining unit and the specific time stored by the specific time storing unit, when the vehicle is started. - View Dependent Claims (13, 14, 15, 16)

17. A drunk driving preventing apparatus installed on a vehicle and including an alcohol sensor, comprising:
-
a test determining unit which determines whether or not to perform a test for detecting alcohol by the alcohol sensor, based on a predetermined condition, when the vehicle is started; a test performing unit which performs the test by the alcohol sensor when the test determining unit determines to perform the test; a control unit which disables driving operation of the vehicle when the test performing unit performs the test and alcohol is detected as a result of the test;
a specific position storing unit which stores a position of a specific place; anda vehicle stopped position obtaining unit which obtains a vehicle stopped position, wherein the test determining unit determines whether or not to perform the test based on the vehicle stopped position obtained by the vehicle stopped position obtaining unit and the position of the specific place stored by the specific position storing unit, when the vehicle is started.

18. A drunk driving preventing apparatus installed on a vehicle and including an alcohol sensor, comprising:
-
a test determining unit which determines whether or not to perform a test for detecting alcohol by the alcohol sensor, based on a predetermined condition, when the vehicle is started; a test performing unit which performs the test by the alcohol sensor when the test determining unit determines to perform the test; a control unit which disables driving operation of the vehicle when the test performing unit performs the test and alcohol is detected as a result of the test; a vehicle stopped time storing unit which stores a vehicle stopped time; and a vehicle stopping time period determining unit which determines a vehicle stopping time period by calculating a difference between the present time obtained by the present time obtaining unit and the vehicle stopped time stored by the vehicle stopped time storing unit, wherein the test determining unit determines whether or not to perform the test if the vehicle stopping time period determined by the vehicle stopping time period determining unit is equal to or longer than a predetermined time period, when the vehicle is started.

19. A drunk driving preventing method executed by a drunk driving preventing apparatus installed on a vehicle and including an alcohol sensor, comprising:
-
a test determining process which determines whether or not to perform a test for detecting alcohol by the alcohol sensor, based on a predetermined condition, when the vehicle is started; a test performing process which performs the test by the alcohol sensor when the test determining process determines to perform the test; a control process which disables driving operation of the vehicle when the test performing process performs the test and alcohol is detected as a result of the test; a specific time storing process which stores a specific time; and a present time obtaining process which obtains a present time, wherein the test determining process determines whether or not to perform the test based on the present time obtained by the present time obtaining process and the specific time stored by the specific time storing process, when the vehicle is started.

20. A computer program product in a computer-readable medium for preventing drunk driving, which is executed by a computer installed on a vehicle and including an alcohol sensor, and which makes the computer function as:
-
a test determining unit which determines whether or not to perform a test for detecting alcohol by the alcohol sensor, based on a predetermined condition, when the vehicle is started; a test performing unit which performs the test by the alcohol sensor when the test determining unit determines to perform the test; a control unit which disables driving operation of the vehicle when the test performing unit performs the test and alcohol is detected as a result of the test; a specific time storing unit which stores a specific time; and a present time obtaining unit which obtains a present time, wherein the test determining unit determines whether or not to perform the test based on the present time obtained by the present time obtaining unit and the specific time stored by the specific time storing unit, when the vehicle is started.
