ABSTRACT:
A sobriety interlock is connectable to a machine such as a vehicle and normally operates to disable the machine from starting unless one or more preconditions, such as the passage of a breath sobriety test, is satisfied. In the event the interlock is bypassed,i.e. the machine started without a prerequisite condition being satisfied, the bypass event is detected and recorded. The record of bypass events preferably includes an indication of each time interval, such as a day, during which at least one bypass event took place as well as the total number of bypass events detected since the sobriety interlock was installed or last serviced. Also disclosed is a remote service device connectable to the interlock by service personnel and useful for such purposes as reading and/or clearing the record of bypass attempts.
