We do not change the standard ignition interlock breath volume setting unless we receive (1) written approval from the court or jurisdiction to lower the breath sample volume or (2) documentation from a licensed physician verifying diminished lung capacity and the need for lowered air volume for a breath sample. In some cases, additional approval from the state authority is also required. Once the required authorization is received, RoadGuard Interlock will lower the volume to the minimum amount sufficient for effective operation of our devices.
