When a driver of a vehicle brings his / her detection part close to a case, a sensor detects a pulse of the driver at the detection part with an optical method, and takes an image of the detection part. An individual certification means determines whether the driver of the vehicle is an authorized person or not based on the image of the detection part taken by the sensor. An alcohol concentration determiner calculates an index value of a blood alcohol concentration of the driver based on the pulse detected at the detection part by the sensor, and determines whether the index value exceeds a criterial value of a drinking assessment. When it is determined that the driver of the vehicle is an authorized person and the index value does not exceed the criterial value of the drinking assessment, a permission means permits the driver to start an engine of the vehicle.

Disclosed is a hand-held device for analyzing the alcohol content found in expelled respiratory gas, the device comprising an outer analyzer housing, a gas analysis and readout assembly, and a control circuit. The expulsion of respiratory gas into the device rotates a fan member. The number of revolutions of the fan member generates a revolution signal that is compared to a predetermined revolution value programmed into the control circuit. When the comparison generates a positive result, alcohol detecting means sample and test the respiratory gas passing through the device. The device thus forces the user to expel so-called low-lung, residual respiratory gas, which gas typically comprises more accurate levels of alcohol as compared to the consumer's blood alcohol content. If the comparison results in a negative signal, the user is prompted to repeat the procedure until a reading of low-lung respiratory gas has been acquired.
