Ignition Interlock in Orange County
An ignition interlock device (IID) is a portable breath-testing instrument that is installed in a DUI offender’s vehicle. They are also knows as breath alcohol ignition interlock devices (BIID).
 They are similar to a Breathalyzer in that they measure the blood alcohol concentration (BAC) of an individual. A significant difference is interlock devices are installed in a vehicle and connected to the engine’s ignition system. The device requires the driver to breathe into it before they can start their car. The interlock device will not allow a vehicle to start if it measures a blood alcohol concentration more than the programmed level in the device. Typically the programmed BAC is 0.02 or 0.04. The device is installed inside the vehicle near the driver’s seat or in the dashboard. The driver must learn specific breath patterns to prevent someone else from blowing into the device to start the car, which is a crime in California. It is also a crime to help or attempt to disable an ignition interlock device.
After the vehicle is started, the ignition interlock device will require the driver to provide breath samples at random pre-set times while the engine is running. If the driver does not provide a sample, or if the sample BAC exceeds the programmed limit, then the ignition interlock device will give a warning, record the event, and slowly bring the vehicle to a stop. The device will trigger specific alarm systems, such as horn honking or lights flashing, until the ignition is turned off. The interlock device will not turn the engine off if alcohol is detected at one of the pre-set tests because that would create an unsafe driving condition. The interlock device does record all events that can be printed out. These logs may be reviewed by the courts, probation department, Department of Motor Vehicles, or other government agency and if violations are found then additional penalties or sanctions may be enforced.
The court can require the installation of an ignition interlock device and the use of them is becoming more common in California. They are being required for the following conditions:
- If the individual is a frequent DUI or DWI offender.
- If the offender had a BAC of 0.10 percent or higher.
- First offenders who refused to take a chemical test to determine their BAC at the time of their arrest.
- If the individual was convicted of driving on a suspended driver’s license if their license was suspended due to a DUI or DWI conviction.
Ignition interlock devices provide an excellent tool for a qualified Orange County DUI lawyer. They may be able to use it to negotiate a better settlement or avoid jail in an appropriate DUI or DWI case.
It is import to note that drunk-driving cases are not the only reason for the installation of an ignition interlock device. The devices can be helpful in any situation where alcohol-free driving is important. Some parents are installing an interlock device to ensure their teenagers are not drinking and driving. Private companies are finding the devices useful to reduce the chance of employees placing others in danger by drinking and driving. Home > Orange County DUI > Ignition Interlock
