Ignition Interlock Devices (IID) In Fresno

What is an Ignition Interlock Device (IID)?

Ignition interlock devices (IIDs) are small DUI breathalyzers that are installed in the dashboard of your car and prevent your from starting and operating your car unless you provide an alcohol-free breath sample. There are four counties in California that require an IID to be installed on a first time DUI conviction. Tulare County is one of those counties. In Fresno, you may be required to install an ignition interlock device in your vehicle after a DUI charge. However, it is not mandatory. It will depend on the circumstances. An ignition interlock device is used in order to monitor a driver's Blood Alcohol Concentration. (BAC). It works by requiring the driver to breathe into a breathalyzer-type device, usually installed on the vehicle's ignition. If the ignition interlock device determines that the driver has consumed alcohol, the device will prevent the engine from starting.

How Does IID Work?

If you blow and the IID does not pick up alcohol, the engine will start and you are free to drive your car. However, be aware that the device will conduct random “running” tests. This “running” test requires the driver to give a breath sample while the vehicle is in use. This helps to prevent other people from initially blowing into the device to get the car started. If you fail the “running” test, the car won't shut off, however, when you stop and shut off the car, you will be locked out and prevented from restarting your car for 5 days. If a driver fails this “running” test, a violation will be registered.

If you blow over the threshold level and the device prohibits you from driving, you will be locked out for a short period of time - approximately a few minutes. However, if you fail subsequent tests, you will be locked out for a more substantial length of time.This device has proven to be very successful in preventing drinking and driving offenses. In fact, the California Department of Motor Vehicles (DMV) has stated that the institution of ignition interlock devices along with monitoring and other programs has decreased DUI offenses by 40-95%.
