A sobriety interlock (1) of the type con- nectable to a machine such as a vehicle (115) and normally operating to disable the machine from starting unless a breath sobriety test is passed, is equipped with a service reminder timer operable to initiate an appropriate indication when the interlock (1) is due to be serviced and optionally, to provide one or more advance indications prior thereto. In the event the interlock (1) is not serviced when due or within an optional grace period thereafter, appro- priate action is preferably initiated. In one alter- native form, this action includes disabling the vehicle (115) or other machine to which the interlock (1) is connected, regardless of whether a sobriety test or other condition normally imposed by the interlock is satisfied, until timely service is obtained. In a second alternative form, the sobriety interlock of the invention does not disable the vehicle for failure to obtain timely service. Instead, the sobriety interlock (1) itself is effec- tively disabled to the extent that it ceases to impose restrictions on the starting of the vehicle until service is obtained and the timer is reset. Also disclosed are remote service devices (55, 56) intended for use by authorized service personnel to inter-alia, effect reading and/or setting of the service reminder timer.
