Choosing the Right Ignition Interlock Device: Factors to Consider

Choosing the Right Ignition Interlock Device

So, you find yourself in the market for an ignition interlock device (IID). Maybe it’s due to a recent DUI conviction, or perhaps you’re a concerned parent wanting to ensure your teen’s safety behind the wheel. Whatever the reason, selecting the right IID is crucial. With many options available, each boasting its own features and benefits, the decision can feel overwhelming. But fear not! We’re here to help.

Understanding Ignition Interlock Devices

Understanding Ignition Interlock Devices

Before we delve into the nitty-gritty of choosing an IID, let’s ensure we’re all on the same page regarding what these devices actually are. An ignition interlock device, such as the devices from Roadguard Interlock, is essentially a breathalyzer for your vehicle. It’s designed to prevent individuals from operating a car if they’ve been consuming alcohol. Once installed, the driver must blow into the device, and if their blood alcohol concentration (BAC) exceeds the preset limit, the vehicle won’t start. Simple, yet effective.

State Requirements and Regulations

First things first, familiarize yourself with the laws and regulations governing IID usage in your state. Requirements can vary significantly from one jurisdiction to another. Some states mandate the installation of an IID for all DUI offenders, while others only require it for repeat offenders or those with particularly high BAC levels. Knowing your state’s specific requirements will narrow down your options and ensure compliance with the law.

Installation and Maintenance

Consider the installation process and ongoing maintenance requirements associated with different IID models. Some devices are relatively straightforward to install and can even be done at home, while others may require professional installation. Similarly, maintenance tasks such as calibration and servicing vary between devices. Opt for an IID that offers ease of installation and minimal maintenance to save time and hassle down the road.

Accuracy and Reliability

When it comes to preventing drunk driving, accuracy and reliability are paramount. You need an IID that consistently delivers precise results to ensure your safety and that of others on the road. Look for devices that undergo rigorous testing and certification to guarantee their accuracy. Additionally, consider reading user reviews and testimonials to gauge the reliability of various models in real-world scenarios.

User-Friendly Interface

Let’s face it: nobody wants to fumble around with a complicated device whenever they need to start their car. Choose an IID with a user-friendly interface that’s easy to understand and operate, even in stressful situations. Features such as clear display screens, intuitive menus, and straightforward instructions can make a world of difference in usability.

Discreet Design

While there’s no shame in prioritizing safety, it’s understandable that you may not want your IID to be a glaring beacon of your past mistakes. Look for devices with discreet designs that blend seamlessly into your vehicle’s interior. Compact units that can be easily concealed from view are ideal for maintaining privacy and avoiding unnecessary attention.

Additional Features

Beyond the basic function of preventing drunk driving, many IIDs offer additional features to enhance convenience and safety. Some models incorporate GPS tracking capabilities, allowing you to monitor the location and movement of your vehicle remotely. Others may offer smartphone connectivity, enabling you to receive notifications and alerts directly to your mobile device. Consider which features are important to you and select an IID that aligns with your needs.

Cost and Affordability

Last but certainly not least, consider the cost and affordability of different ignition interlock devices. Prices can vary widely depending on factors such as brand, features, and installation requirements. While it’s tempting to opt for the cheapest option available, remember that quality and reliability should take precedence when it comes to something as critical as preventing drunk driving. Evaluate your budget carefully and choose an IID that offers the best value for your money.

Installation Process Simplified

Now, let’s break down the installation process to give you a clearer picture of what to expect. While specific steps may vary depending on the make and model of your vehicle and the IID you choose, the general process typically follows these basic steps:

  1. Choose a Certified Provider: Select a reputable ignition interlock device provider. Ensure that the provider is certified and authorized to install IIDs in your state to avoid any legal complications.
  2. Schedule an Appointment: Contact the provider to schedule an installation appointment at a convenient time and location. Be sure to inquire about any documentation or paperwork you’ll need to bring with you.
  3. Vehicle Assessment: On the day of your appointment, the technician will assess your vehicle to determine the most suitable location for installing the IID. They’ll take into account factors such as accessibility and visibility to ensure optimal functionality.
  4. Installation Process: The technician will then proceed to install the ignition interlock device according to the manufacturer’s instructions. This typically involves connecting the device to your vehicle’s electrical system and mounting it in a discreet yet accessible location.
  5. Testing and Calibration: Once the device is installed, the technician will conduct thorough testing to ensure it functions correctly. This may involve calibrating the device to ensure accurate readings and responsiveness.
  6. Training and Education: Before completing the installation process, the technician will provide comprehensive training on using the IID effectively. They’ll walk you through the startup procedure, explain any error codes or indicators, and answer any questions you may have.
  7. Documentation and Compliance: Finally, the technician will provide you with all necessary documentation, including proof of installation and compliance with state regulations. Be sure to keep these documents in a safe place and readily accessible in case you need them in the future.


By taking the time to research and compare different models, you can select an IID that meets your needs and helps keep you and others safe on the road. Remember, safety always comes first. Drive responsibly, and never drink and drive.
