A vehicle ignition interlock system includes a breath analyzer, a transderma l alcohol sensor configured to be worn by the vehicle operator, and a controll er operably connected to the breath analyzer, to the transdermal alcohol sensor , and to an ignition system of the vehicle. The transdermal alcohol sensor is configured to be worn by the vehicle operator, and is configured to detect alcohol through the skin of the vehicle operator. The controller is configur ed to override one or more periodic breath analyzer retests if alcohol is not detected through the skin of the operator by the transdermal alcohol sensor. The controller is configured to increase the frequency of periodic breath analyzer retests of the vehicle operator in response to the transdermal alcohol sensor detecting alcohol through the skin of the operator. A proximi ty sensor detects proximity of the transdermal alcohol sensor relative to a vehicle operator area.
