When Is An Ignition Interlock Device Required?

Imagine this: you’ve had a great night out with friends, but now it’s time to head home. You might think you’re okay to drive, but the reality is, alcohol impairs judgement. That’s where ignition interlock devices come into play. They may appear to be an inconvenience, but in truth, they save lives.

So, what exactly is an ignition interlock device? It’s a small device installed in your vehicle that makes sure you’re sober before you can start the engine. In this article, we’ll ensure you understand the ins and outs of these devices and make sure you know you might need to have an interlock ignition device installed in your vehicle.

What is an Ignition Interlock Device?

An ignition interlock device is a helpful tool that is installed in cars, trucks, and motorbikes to protect drivers, passengers and pedestrians from the dangers of drink driving. Generally used as a mandate following drink driving charges, this compact device is seamlessly connected to your vehicle’s ignition, preventing it from starting until the driver provides a breath sample that’s free from alcohol.

Here’s how it works: Before you can hit the road, you simply blow into the interlock device’s mouthpiece. If your breath sample falls within the acceptable range, the interlock gives you the green light to start your vehicle. If, however, the device detects alcohol levels above the predetermined limit, the information will be stored within the system, and alarms will sound out.

These interlock devices are about the size of a mobile phone, and they use advanced technology, including ethanol fuel sensors, to ensure precise and reliable readings every time you use them. Even though the legal blood alcohol concentration (BAC) limit for fully licensed drivers varies by location, these devices leave no room for alcohol in your breath test, aligning perfectly with safety guidelines.

But the benefits of ignition interlock devices don’t stop there. They’re not just about rules and regulations; they’re about keeping you, your passengers, and everyone else on the road safe. By separating drinking and driving, these devices play a vital role in preventing accidents and promoting responsible behaviour. This makes them a vital rehabilitation tool, contributing to positive outcomes in road safety today and tomorrow. 

When Is An Ignition Interlock Device Required? 


Legal Requirements and Drink Driving Convictions

All Australian states and territories carry out Alcohol Interlock Programs that assist individuals in safely returning to driving and assisting them in their rehabilitation following a drink driving conviction. Participation in these programs is mandated by the conviction and the duration that each individual participates in the program depends on the severity of their conviction (which is determined by their Blood Alcohol Content). 

The length of time imposed by the state authority is determined by the range of the alcohol reading i.e Low, Mid or High, how many previous offences have occurred and any specific conditions imposed by the licence. 

Voluntary Installation and Private Use

In addition to legal requirements, some individuals choose to install ignition interlock devices voluntarily for various reasons. Athletes, individuals following company policies, or those who want an extra layer of personal safety typically opt for voluntary use. The advantages are clear: it’s a responsible choice that prioritises safety for both the driver and others on the road.

Understanding when an alcohol interlock device is required is vital, as it helps us all take responsibility for our actions and make informed choices when it comes to drinking and driving. Whether it’s a legal obligation or a personal decision, these devices are crucial in promoting safer roads and responsible behaviour.
