Abstract
A breath alcohol detection device includes a one-piece multi-passage block with attached sensors, a valve and a fuel cell. The cell accurately determines the BrAC of a prospective vehicle operator. In the event the BrAC is less than the legal maximum for a territory, the device unlocks an ignition interlock to permit starting of the engine and operation of the vehicle.
