1. What is an ignition interlock device?

An ignition interlock device is a device installed in a vehicle that requires the driver to take a breath alcohol test before starting the car. If the breath sample exceeds a preset limit, the car will not start. It is commonly used as a requirement for individuals convicted of driving under the influence (DUI) offenses.

2. How does an ignition interlock device work?

An ignition interlock device is a small electronic device installed in a vehicle that prevents the engine from starting unless the driver passes a breathalyzer test. The device is connected to the vehicle’s ignition system and requires the driver to blow into a mouthpiece, similar to a breathalyzer used by law enforcement, before starting the vehicle. When a driver blows into the device, it measures their blood alcohol concentration (BAC). If the level is below the preset limit, usually around 0.02%, then the vehicle will start normally. However, if the BAC level is above the limit, the vehicle will not start.

In addition to this initial test, most ignition interlock devices also require periodic retests while driving. This ensures that the driver remains sober throughout their trip. Failure to pass a retest will not shut off or stall out the engine while driving, but an alarm will sound until the vehicle is turned off or until another retest is passed.

The device also records all tests and results, which are typically reviewed by monitoring authorities such as court officials or probation officers. If any attempts are made to tamper with or circumvent the device, it will be detected and considered a violation of DUI terms.

Overall, an ignition interlock device works by preventing individuals from operating their vehicle while under the influence of alcohol and providing accountability for individuals with past DUI offenses.

11. How does an ignition interlock device monitor alcohol levels in your breath?

An ignition interlock device (IID) uses a fuel cell sensor to monitor alcohol levels in your breath. When you blow into the device, your breath passes through the fuel cell and any alcohol present in your breath reacts with the electrodes in the fuel cell, producing an electrical current. The strength of this current is directly proportional to the amount of alcohol in your breath. The IID translates this current into a digital reading that is compared to a pre-set limit to determine whether or not your vehicle should start.

12. How will I know if I pass or fail a breathalyzer test on my ignition interlock device?

You will receive a pass or fail result on the device’s display screen after you have completed the breath test. If you pass, the vehicle will start and you can continue driving. If you fail, the vehicle will not start and you may be required to take additional action, such as waiting a certain amount of time before attempting another breath test. Your device provider should also provide detailed information on how to interpret these results and what steps to take if you fail a test.

13. Are there any special considerations for people with certain medical conditions when using an ignition interlock device?

Some medical conditions may interfere with the proper functioning of an ignition interlock device.
