How Does An Interlock Work In Missouri? Exploring The Ins And Outs Of Interlock Devices

By Mariah Cannon

In this article, we will delve into the world of interlock devices and explore how they operate in the state of Missouri.

An interlock device, also known as an ignition interlock, is a breathalyzer installed in a vehicle to prevent individuals from driving under the influence of alcohol.

We will discuss the functionalities, requirements, and regulations surrounding interlock devices in Missouri. So, buckle up as we take a ride through the intricate details of interlock devices in the Show-Me State.

Understanding Interlock Devices

Before we dive into the specifics of how interlock devices work, let’s first understand the basic principles behind these devices.

Interlock devices are designed to measure the blood alcohol content (BAC) of a driver before allowing the vehicle to start.

The driver must blow into the device, and if the BAC level is above a preset limit, usually 0.02%, the vehicle will not start.

Components of an Interlock Device

An interlock device consists of several key components that work together to ensure accurate BAC measurements and prevent impaired driving.

These components typically include:

  • Breathalyzer: The device that measures the BAC level in the driver’s breath.
  • Control unit: Processes the breath sample and determines if the vehicle should start.
  • Relay: A mechanism that controls the vehicle’s ignition based on the results of the BAC test.
  • Camera: Some interlock devices are equipped with a camera to capture images or videos during the breath test.

The Legal Landscape in Missouri

Now that we have a foundational understanding of interlock devices, let’s shift our focus to Missouri and examine the laws and regulations governing the use of these devices in the state.

Missouri Interlock Laws

In Missouri, the installation of an interlock device may be required for individuals convicted of driving under the influence (DUI) or driving while intoxicated (DWI) offenses.

The specific requirements and duration of the interlock program vary based on the circumstances of the offense and prior convictions.

Missouri Interlock Program

The Missouri Department of Revenue oversees the state’s Ignition Interlock Program, which mandates the installation of interlock devices for certain DUI and DWI offenders.

Participants in the program are responsible for the costs associated with the device installation, maintenance, and monitoring.

Installing an Interlock Device

The process of installing an interlock device involves several steps, from selecting an approved provider to completing the installation and calibration of the device.

Choosing an Approved Provider

Before installing an interlock device, individuals in Missouri must select a state-approved provider.

It is essential to verify that the chosen provider meets the requirements set forth by the Missouri Department of Revenue. This ensures compliance with the state’s regulations.

Installation and Calibration

Once a provider has been selected, the next step is to schedule the installation of the interlock device in the vehicle.

During the installation process, the device will be calibrated to accurately measure BAC levels.

Calibration is crucial to the device’s effectiveness and reliability.

Training and Compliance

After the device has been installed and calibrated, participants in the Missouri Interlock Program are typically required to undergo training on how to use the device properly.

It is essential to follow all guidelines and instructions provided by the device manufacturer and program administrators to ensure compliance and successful completion of the program.

Operating an Interlock Device

Now that we have covered the installation process, let’s explore how an interlock device operates on a day-to-day basis for drivers.

Breath Testing

One of the primary functions of an interlock device is to conduct breath tests to measure the driver’s BAC levels.

Drivers are usually required to blow into the device before starting the vehicle, as well as at random intervals while driving, to ensure sobriety.

BAC Thresholds In Missouri

In Missouri, interlock devices are typically set to trigger a violation if the driver’s BAC level exceeds 0.02%.

If a violation occurs, the device may record the event, alert the driver, and in some cases, initiate consequences such as disabling the vehicle’s ignition.

Data Logging and Reporting

Interlock devices are equipped with data logging capabilities that record BAC test results, violations, and other relevant information.

This data is often reported to program administrators for monitoring compliance and enforcing program requirements.

Maintaining Compliance

To successfully navigate the Missouri Ignition Interlock Program, participants must adhere to the rules and regulations governing the use of interlock devices.

Scheduled Maintenance

Regular maintenance and calibration of the interlock device are essential to ensure accurate BAC measurements and proper functionality.

Participants are required to schedule periodic maintenance appointments with their approved provider.

Reporting Violations In Missouri

In the event of a violation or malfunction of the interlock device, firstly participants are obligated to report the issue to program administrators promptly.

Failure to report violations or comply with program requirements may result in penalties or program extension.

Costs and Insurance Implications

Apart from the legal obligations and operational aspects, it is crucial to consider the financial implications of installing an interlock device in Missouri.

Installation and Monthly Fees

The cost of installing an interlock device in Missouri can vary depending on the provider and specific device model.

In addition to the installation fee, participants may also incur monthly maintenance fees for device calibration and monitoring.

Insurance Considerations

The installation of an interlock device may impact an individual’s auto insurance rates nonetheless.

Some insurance companies view participation in the Interlock Program as a high-risk factor. This could lead to higher overall premiums or policy cancellations.
