Alchol Interlock: The Need to Know
08 April, 2024
An alcohol interlock is a safety device in a vehicle that prevents the driver from starting the vehicle if they have consumed alcohol. It works by requiring the driver to blow into a breathalyser before initiating the engine. The vehicle will not start if alcohol is present in the breath sample. To install the ignition interlock device, the driver must contact an interlock service provider.
Driving Under the Influence (DUI) remains a significant factor in numerous accidents and fatalities. It prompts law enforcement agencies to conduct roadside testing for enhanced road safety measures. People caught with either a high-range drinking offence or multiple lower offences may face licence suspension, mandatory counselling, and educational sessions. Installation of an interlock device is another possible penalty. This article will provide insights into alcohol ignition interlock devices, their operational mechanisms, and the installation process.
What is an Alcohol Interlock Device?
An alcohol interlock device is a machine installed in a motor vehicle. Its primary purpose is to prevent ignition interlock program participants from driving if they are under the influence of alcohol and monitor them. Several types of ignition interlock devices come with various features to help ensure they can fulfil this purpose.
The standard model is the Breath Alcohol Ignition Interlock Device (BAIID). This traditional unit uses a tube to collect the breath specimen. Another type is the Vehicle Alcohol Detection System (VADS), which uses infrared spectrometry. This is an advanced equipment that provides very accurate results.
An interlock condition is a penalty imposed on individuals convicted of high-range drink driving. This can be due to being caught with a Blood Alcohol Concentration (BAC) level of 0.14% or higher or multiple lower-range offences. However, some may petition for an interlock exemption due to valid reasons. Generally, exemptions can be made for those who cannot afford the financial burden of an interlock program.
Purpose of Interlock Programs
- Prevents drink driving: Interlock programs aim to stop people from operating a vehicle while under the influence of alcohol.
- Promotes road safety: They ensure safer roads by reducing the risk of accidents caused by impaired driving.
- Rehabilitation tool: Interlock programs offer a chance for people with DUI offences to rehabilitate.
- Deters subsequent offences: Requiring an interlock device discourages people from committing further drink driving offences.
- Legal compliance: Interlock programs fulfil legal requirements imposed on individuals with DUI convictions.
- Monitoring mechanism: They provide a means for authorities to monitor and track the compliance of the offender with sobriety conditions.
How Alcohol Interlock Devices Work
An alcohol interlock device works by requiring the driver to blow into a breathalyser before starting the vehicle. It utilises a fuel cell sensor to examine alcohol in the breath. This technology provides a highly accurate measurement of the BAC or the concentration of alcohol in the bloodstream.
If the BAC is above the pre-set limit, the motor vehicle will not start. Hence, the driver must wait for a specified period before attempting another test. This ensures that any residual alcohol in the mouth does not affect subsequent readings. In addition, interlock devices may require random breath samples while driving to ensure continued sobriety. If the driver fails to retest, it may set off an alarm or flashlights to alert authorities.
The ignition interlock device also requires monthly recalibration to ensure accurate readings. The person must bring the vehicle to the interlock provider for servicing, including downloading data and checking for any tampering attempts. Failure to comply with these requirements may result in penalties or a more extended interlock period.
Consequences for Failing to Provide a Breath Sample
Consequences for failing to provide a breath sample in an interlock program can vary depending on the location and circumstances. Firstly, if a person does not blow into the device when prompted, their car will not be able to start. Secondly, they may be required to use the interlock for a longer period of time, extending the program duration.
Thirdly, authorities might impose fines or penalties and suspend their licence. Not following the rules could lead to more legal trouble, including facing extra charges or legal action. Therefore, individuals must comply with the program requirements to steer clear of these consequences.
Installation Process for Alcohol Interlock Devices
Firstly, a person gets a mandatory alcohol interlock program after a conviction for a drink driving offence. The individual applies for an interlock service provider and schedules an installation appointment. This may include paying the necessary fees and signing a lease agreement. The service centre will then install the device in the vehicle by connecting it to the ignition system.
Secondly, the technician will explain how to use the interlock and provide training on its operation. The program participant will learn how to provide a breath specimen correctly and what to do in case of a failed test. Furthermore, they will set the alcohol limit based on legal requirements or court orders. The offender is responsible for interlock costs, including installation fees and monthly service.
After the installation, the participant must follow the program guidelines strictly. Regular maintenance and calibration are essential to ensure accurate readings. It is important to note that only the interlock provider can install and remove the device. Any attempts to tamper with or bypass the system may result in penalties or an extension of the interlock condition.
Requirements for Installation
The requirement for installation of interlock devices depends on several criteria. In general, people with multiple drink driving offences on their record are required to install the device in their vehicle. A court may order the mandatory installation of the device as part of a sentencing condition for a DUI conviction, regardless of their BAC levels.
Additionally, it involves individuals with a BAC level of 0.15% and higher at the time of the police breath test. This applies to both repeat and first-time offenders. These alcohol concentration levels typically cause significant impairment and pose a greater risk of causing accidents.
Conclusion
An alcohol interlock device is a crucial tool in preventing drink driving incidents. By requiring drivers to pass a breath test before starting the vehicle, it ensures safety on the roads. These devices use advanced technology to accurately measure blood alcohol levels and prevent ignition if the limit is exceeded. Regular recalibration and monitoring are essential to maintain effectiveness. Some people may qualify for exemptions due to financial reasons.
The installation process is straightforward. Offenders must apply for an interlock service provider and schedule an installation appointment, paying fees and signing agreements. Technicians explain device usage and set alcohol limits based on legal requirements. Tampering or bypassing the system can lead to penalties. Installation requirements vary but generally apply to repeat offenders or those with high BAC levels. Ultimately, these devices play a vital role in preventing drink driving accidents by ensuring accountability and sobriety behind the wheel.
