Ignition Interlock

Find a Provider

After a DUI conviction, most states require the use of an Ignition Interlock for some period.  An Ignition Interlock Device (IID) is a breathalyzer that will prevent a car from starting if presented with alcohol.  How the Ignition Interlock works is, before the car will start, the driver is required to blow into the mouthpiece and only if the breath alcohol content (BAC) presented is below the limit set by the state, the car will start. Once the car is started, you are required to test randomly while you drive.

Things that Matter:

  • If required, you cannot operate a vehicle without an Ignition Interlock.

  • Make sure that the Ignition Interlock provider has a good service record and a reliable product.
  • A faulty device or poor customer service could leave you stranded and unable to operate your vehicle.
  • Interlock devices are required to go through routine calibration inspections.

Helpful Tip:

The price of the unit is not the only costs of an Ignition Interlock; make sure to inquire about other fees (Removal/Reinstall for switching cars, change/missed/late appointments, violations, maintenance).  Ask about 24-hour mobile assistance and/or response time guarantees. Make sure you read all the terms and conditions associated with the interlock device.
