In Australia, the alcohol interlock device is an electronic breath-testing gadget that has been integrated with the ignition systems of a range of vehicles, from cars to heavy trucks, and is specifically designed to curb the scourge of drink-driving on our roads.

It is a legal requirement for drivers to furnish a breath sample using the Guardian Interlock device which analyses the breath for the presence of alcohol before allowing the vehicle to start. This serves as a preventative measure against the operation of vehicles under the influence of alcohol. In addition, the alcohol interlock is designed to carry out randomly timed breath tests during the course of a journey to further ensure that the driver is not intoxicated.

The alcohol interlock program goes a step further in some states or under certain circumstances by including a camera that captures a photograph of the person providing the breath sample. This feature helps to prevent any attempt to circumvent the program by an intoxicated driver or by someone else providing a sample on behalf of the driver.

There are various factors that can result in an interlock device preventing a driver from starting their vehicle. One of the most conspicuous reasons for this occurrence is the detection of alcohol in the sample provided by the driver. However, it is essential to note that the detection of alcohol does not necessarily mean that the driver has consumed alcohol. Several products that contain alcohol can trigger a positive result in the interlock device. Therefore, it is imperative to exercise caution when using such products to avoid any inconveniences when starting your vehicle.

Reasons you might be locked out of starting a vehicle with an interlock device

When it comes to providing a sample for an interlock device, it's important to keep in mind that certain products we use in our everyday lives can affect the accuracy of the device's readings. Toothpaste, mouthwash, cough medicine, vanilla extract, windshield cleaners, and hand sanitizers are all products that may cause a slight impact on the readings.

While it's not necessary to completely avoid these products altogether, it's recommended that you refrain from using or ingesting any products containing alcohol immediately prior to providing a sample for the interlock device. This can include items such as mouthwash or cough medicine which often contain alcohol. Additionally, if you do choose to use a hand sanitizer before getting into the car, it's important to do so outside of the vehicle.

There are various reasons that may lead to a situation where you find yourself unable to start your vehicle, one of which is a missed scheduled service appointment. As a responsible car owner, you should ensure that you receive timely notifications and reminders for scheduled service appointments for your vehicle. Missing one of these appointments could result in a severe consequence - a permanent lockout, which means you won't be able to start your car at all.

If such an unfortunate event takes place, don't panic. There's still a way out. You can have your vehicle towed to an authorised Guardian Interlock Service Centre, such as The Auto Repair Shop, where you can have a Lockout Reset performed.

Interlock devices are ingeniously designed to safeguard against any attempts to tamper or manipulate them without adhering to the protocol of providing a breath sample. Any efforts to disable or remove the device will lead to permanent vehicle lockout until the system can be reset. Hence, it is advisable to contact an authorised agent for assistance when carrying out any repairs on your car, to prevent getting locked out or falling foul of state regulations. Simple actions like disconnecting or removing the battery can trigger an interlock lockout, requiring a mechanic's affidavit and a special code to safely conduct any maintenance tasks without contravening the device's operational guidelines.

It is crucial to adhere strictly to the regulations governing the operation of the interlock device to avoid any legal issues and to ensure your vehicle's uninterrupted functionality.

An alcohol interlock is a breath-testing device connected to a vehicle’s ignition and stops a driver from starting a vehicle if they have been drinking alcohol. Alcohol Interlocks can be fitted to most types of vehicles, including cars, motorbikes, and trucks.

An interlock device is connected to your vehicle with a preset level for blood alcohol concentration (BAC). This is typically very low, so any alcohol or even using alcohol containing products can cause a test failure.  If you blow into it when you are over the set limit, your vehicle won’t start.

You will need to have regular service appointments for your interlock device to ensure it is operating correctly and failure to attend appointments may result in you being locked out of starting the vehicle and having to get it towed to the nearest service Centre.
