How Does an Ignition Interlock Device Work?
July 17, 2024
An ignition interlock device is an apparatus installed in a vehicle to prevent it from starting if the driver's blood alcohol concentration (BAC) is above a pre-set limit. This device serves as both a preventative measure and a deterrent for those with a history of drunk driving.
You might wonder how the ignition interlock device (IID) in your vehicle functions. Bretz Legal, LLC is here to help you learn everything about IIDs, their components, operations, benefits, and Missouri laws related to them.
Key Components of an Ignition Interlock Device
The primary parts of an IID include a breathalyzer, a control unit, and a handset. The breathalyzer measures the driver's BAC. The control unit processes the breathalyzer's readings and determines whether to allow the vehicle to start. The handset displays instructions and captures the driver's breath sample.
How It Works
When the driver attempts to start the vehicle, they must breathe into the IID. If the device detects a BAC level above the legal limit, it prevents the engine from starting. The IID will also require periodic retests while the vehicle is in motion to ensure the driver remains sober throughout the trip.
Safety Benefits of Ignition Interlock Devices
Beyond merely stopping a vehicle from starting, IIDs provide several safety advantages. They address the issue of repeat offenders by enforcing sobriety before and during vehicle operations. Studies have shown that states implementing mandatory IID programs see a significant reduction in alcohol-related traffic incidents.
Reducing Repeat Offenses
Studies indicate that IIDs can reduce repeat offenses by up to 70%. Drivers with previous DUI convictions are less likely to re-offend when they know that their vehicle won't start if they have been drinking.
Peace of Mind for Families
For families with members who have a history of alcohol abuse, an IID offers peace of mind. Knowing that a drunk family member won't be able to drive can significantly reduce stress and worry.
Enhancing Public Safety
By keeping impaired drivers off the road, IIDs contribute to overall public safety. This protects the driver and other road users, making the roads safer for everyone.
How to Use an Ignition Interlock Device
Using an IID is relatively straightforward once you understand the steps involved. This section will guide you through using the device effectively.
Breath test before starting: Each time you want to start your vehicle, you must blow into the IID. Follow the on-screen instructions to provide a correct breath sample.
Periodic retests: While driving, the device prompts you to take periodic retests to ensure that you haven't consumed alcohol since the initial test. Failure to take these retests can result in nonstop honking or lights flashing until the vehicle is turned off.
Regular maintenance: Stay up-to-date with regular maintenance and calibration appointments to keep the device accurate and compliant with Missouri law.
Tips for Accuracy
Avoid consuming food or drinks shortly before using the IID.
Follow the manufacturer's instructions for providing a breath sample.
Schedule maintenance appointments in advance to avoid non-compliance.
Common Myths About Ignition Interlock Devices
There are several myths about IIDs that can deter people from understanding their benefits and proper use. Let's debunk some of these myths.
Myth 1: IIDs are Invasive
Many people believe that an IID is an intrusive device. In reality, the device promotes safety and is discreet and easy to use.
Myth 2: IIDs are Only for Repeat Offenders
While IIDs are commonly associated with repeat DUI offenders, many states, including Missouri, mandate their use for first-time offenders as well.
Myth 3: IIDs are Easy to Bypass
Technological advancements have made modern IIDs quite sophisticated, making them difficult to bypass. Attempts to tamper with or disable the device are usually detected and reported, leading to further legal consequences.
Choosing the Right Ignition Interlock Device Provider
Here are some factors to consider while selecting the right IID:
Certified providers: State-certified providers adhere to strict guidelines and offer reliable services.
Customer support: Look for a provider that offers robust customer support.

Violating the terms of IID usage can have severe legal consequences.
Tampering with the device: Tampering with or attempting to bypass the IID is a serious offense. Such actions are usually detected and reported, leading to additional fines and extended IID usage.
Failed tests: Failing a breath test can result in the vehicle being disabled. Repeated failures can lead to more severe penalties, including license suspension.
Missed maintenance: Skipping scheduled maintenance or calibration appointments can flag the IID as non-compliant. This can lead to additional penalties and possibly extend the duration of IID usage.
