A method for preventing circumvention of a intoxication test includes defining a detection time envelope with a first sensor activated in response to the presence of a human test subject proximate the first sensor and sensing with a second sensor for a change from an ambient condition caused by the presence of the human test subject proximate the second sensor. The intoxication test is validated when a change from the ambient condition is detected by the second sensor during the time envelope defined by the first sensor.
