What’s an ignition interlock device?

  • A small breath analyzer that requires a clean, alcohol-free breath sample by a driver in order to start a vehicle.

What’s the purpose of the device?

  • Ignition interlocks are used across the nation as an alternative to license revocation.
  • When the law takes away individuals’ licenses for a substantial period of time, life as they know it becomes difficult (i.e. supporting a job, family and normal lifestyle).
  • Ignition interlocks are an alternative to revocation. They provide those convicted of a DWI with the opportunity to prove they can be responsible drivers again.
  • That’s why Monitech calls it the ‘road to redemption.’

Which drivers are required to have an ignition interlock device by N.C. law?

  • Those convicted of a DWI type offense with a 0.15 or higher BAC
  • Those with a prior DWI conviction or record required to drive an ignition interlock-equipped vehicle

How long are individuals required to have an ignition interlock device?

  • Terms range from one to 10 years depending on the number of convictions.

What happens if the device detects alcohol?

  • If the device records a FAIL, a noncompliance report is sent to the DMV.

Can anything other than alcohol (ethanol) set off the device?

  • A FAIL can occur due to mouth contaminants.

What are examples of mouth contaminants?

  • Some foods and drinks other than beer, wine and liquor include alcohol type ingredients.

What should you do if your device detects a mouth contaminant?

  • If a driver consumes a mouth contaminant before activating the device, it will result in a WARN or FAIL.

By that time, any contaminant should have dissipated.
