The present invention relates to vehicle breath monitors, and in particular to a vehicle breath monitoring system which either inhibits the starter motor solenoid of a motor vehicle or gives other indication when a driver's breath sample has an alcohol level above the legal limit. The system comprises an electro-chemical fuel cell assembly, which measures the level of ethanol of a breath sample supplied by the driver. The output of the fuel cell is fed to a microprocessor which uses the data as well as data of the ambient condition to determine the alcohol level of the driver's blood. The operation of the system requires the driver to use the system prior to the initial start of the motor vehicle, and a second repeat test to ensure that the alcohol level has not risen over time. If the tests are not passed the system gives an indication to the driver of the results so that the driver can act accordingly. |
