Alcohol interlock devices have become increasingly popular in many countries in recent years to prevent drivers from operating a vehicle while under the influence of alcohol. But how exactly do these devices work? In this article, we explore the mechanism behind alcohol interlock devices and what makes them so effective. From technology to installation, we’ll explain everything you need to know about this innovative and effective device.
An alcohol interlock device is designed to prevent a driver from operating a vehicle if they have been drinking alcohol. It works by taking a breath sample from the driver before the vehicle can be started. If the breath sample contains alcohol, the vehicle will not start. If the sample is clear, the vehicle will start as normal.
The device requires the driver to blow into a breathalyzer, which measures the alcohol content in their breath. If the breathalyzer detects a blood alcohol concentration (BAC) of 0.02% or higher, the vehicle will not start. The driver will then be required to wait a certain amount of time before they can attempt to start the vehicle again.
The device is typically installed in the vehicle by a qualified technician, and must be regularly calibrated to ensure accurate readings. Once installed, the device must be used each time the vehicle is started, and will record the results of each test.
What is an Alcohol Interlock Device?
An alcohol interlock device, also known as an ignition interlock device (IID) or car breathalyzer, is a device that is installed in a vehicle to prevent drivers from operating the vehicle if they have been drinking alcohol. The device is designed to measure a driver’s breath alcohol concentration (BrAC) and will not allow the vehicle to start if the BrAC is above a preset level. The device is typically installed as a condition of a person’s probation after they have been convicted of a DUI/DWI offense.
The device acts as a deterrent, reminding drivers of their commitment to sobriety and discouraging them from drinking and driving. It also helps to protect other drivers from the dangers of a drunk driver. The device is installed in the vehicle by a certified technician and requires the driver to provide a breath sample prior to starting the vehicle. If the driver’s BrAC is above the preset level, the vehicle will not start.
How Does an Alcohol Interlock Device Work?
An alcohol interlock device is a breathalyzer that is connected to the starter and ignition system of the vehicle. When the driver wishes to start the vehicle, they must blow into the device and provide a breath sample. The device will then measure the driver’s breath alcohol concentration and compare it to the preset level. If the BrAC is above the preset level, the vehicle will not start.
When the device is installed, the driver is required to enter a code on the device. This code is used to identify the driver and ensures that only the driver of the vehicle can provide a breath sample. Once the breath sample is provided, the device will measure the BrAC and if it is below the preset level, the vehicle will start.
The Benefits of an Alcohol Interlock Device
The most obvious benefit of an alcohol interlock device is that it helps to deter drivers from drinking and driving. The device is a reminder to drivers of their commitment to sobriety and encourages them to make good decisions.
In addition, the device can help to save lives. By preventing drivers from operating a vehicle if they are impaired, the device helps to make the roads a safer place. It also protects other drivers from the dangers associated with a drunk driver.
What Happens if the Vehicle Does Not Start?
If the BrAC is above the preset level, the vehicle will not start. The driver will be required to wait a few minutes and then try again. If the vehicle still does not start, the driver must contact a certified technician to have the device serviced. The technician can then reset the device and allow the driver to start the vehicle.
What Are the Penalties for Violating an Alcohol Interlock Device?
If a driver attempts to start the vehicle with an alcohol concentration that is above the preset level, they will be in violation of the terms of their probation and may be subject to additional penalties. These penalties can include fines, imprisonment, and license suspension or revocation.
How Long Does an Alcohol Interlock Device Need to Be Installed?
The length of time that the device must be installed can vary depending on the state and the terms of the driver’s probation. Generally, the device must be installed for at least six months, but it can be required for up to three years in some cases.

What is an alcohol interlock device?
An alcohol interlock device is a breathalyzer installed in a vehicle. It prevents the vehicle from starting if the driver’s breath alcohol concentration (BrAC) exceeds a preset limit. In some states, it is required by law for drivers with a history of alcohol-related offenses.
How does the alcohol interlock device work?
The alcohol interlock device requires the driver to provide a breath sample before the engine can start. If the BrAC level is higher than the preset limit, the device will prevent the engine from starting. The driver may need to wait a few minutes and try again. The device will also periodically require the driver to provide additional breath samples while the vehicle is in motion. If the BrAC level is too high, the device will sound an alarm and the vehicle will not be able to be driven.
Who is required to install an alcohol interlock device?
In many states, drivers who have been convicted of a DUI are required to install an alcohol interlock device in their vehicles. Some states also require alcohol interlock devices for drivers who have been convicted of other alcohol-related offenses.
How much does an alcohol interlock device cost?
The cost of an alcohol interlock device varies depending on the type of device and the installation company. Generally, the cost of the device and installation is between $75 and $200. Some states also require the driver to pay a monthly fee for monitoring and calibration of the device.
What happens if the driver fails the test?
If the driver fails the breath test, the vehicle will not start and the driver will need to wait a few minutes before trying again. The driver will also be required to take additional breath tests while the vehicle is in motion. If the BrAC level is still too high, the device will sound an alarm and the vehicle will not be able to be driven.
Can the alcohol interlock device be bypassed?
No. Alcohol interlock devices are designed to prevent attempts to bypass them. They are equipped with tamper-proof features that detect any attempt to alter the device or bypass it. Attempts to bypass the device may result in fines or other penalties.
In conclusion, an Alcohol Interlock Device is a highly effective countermeasure against drinking and driving, as it prevents vehicles from starting if the driver has consumed alcohol. The device is effective and reliable, and is an important tool in ensuring that our roads remain safe. If you are convicted of an alcohol-related driving offence, an Alcohol Interlock Device may be a requirement of your sentence. The device is easy to install, and can be monitored to ensure that drivers remain compliant with the terms of their sentence.
