Monitech Ignition Interlock Monitoring, also known as the IID Ignition Interlock Device or the “Blow-and-Go” is sometimes mandated as a condition for operating a motor vehicle in North Carolina.  The purposes of “monitoring” include:

• Preventing an operator from STARTING a car if the Blow-and-Go detects the presence of alcohol
• Require “Rolling” testing while operating a motor vehicle* to confirm Ethanol hasn’t been consumed after the start-up protocol
