Abstract: A new system monitors ethanol alcohol levels of a vehicle operator by collecting sweat from the operator's hands, and detecting the presence, if any, of ethanol in the sweat. The system can then be used, if ethanol is present, to take action, such as immobile vehicle disablement, in the event of intoxication caused by an impermissibly high levels of ethanol of the operator. The system includes devices, referred to as pods in the description, which are sweat-collecting devices that are attached to the steering wheel of the vehicle. If the measurable ethanol in collected moisture from the operator's hands exceeds a preset threshold, the system could be configured to warn the operator to park the vehicle thereafter to disable operation of the vehicle, but if the operator does not so discontinue operation of the vehicle hazard warning lights and audible warnings within and without the vehicle will be activated alerting near vehicles of a dangerous vehicle being operated in close proximity.
