An Ignition Interlock Device (IID) is a breathalyzer that prevents a car from starting if presented with alcohol. 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:
- Make sure 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.
- Ignition interlock devices are required to go through routine calibration inspections.
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.
