Alcohol Interlock Removal in Victoria: Eligibility, Timing and the Five-Month Rule

If you're nearing the end of your interlock period, the question on your mind is probably simple: when can I get this thing out of my car? 

Getting your alcohol interlock removed in Victoria isn't automatic. You need to apply, meet eligibility rules, and clock up a clean run of violation-free months first. Here's exactly what's involved, including the five-month rule that catches many people out.

Quick Answer

• Removal isn't automatic. You must apply through the Alcohol Interlock Management System (AIMS) or VicRoads once you're eligible.

• You need a minimum number of clean months on your alcohol interlock before applying, and any violation resets that clock.

• The "five-month rule" means at least five consecutive violation-free months are required if you've had a failed reading along the way.

• Drivers who have completed the Intensive Behaviour Change Program will also be required to complete a 2-hour Pre-Interlock Removal behaviour change program before they can apply.

• You can't legally drive any vehicle without the interlock device fitted while your licence carries the 'I' condition.

  
  

What Does Having an Alcohol Interlock Condition Mean?

Once you're relicensed after a drink driving offence in Victoria, your licence is usually issued with an 'I' condition, meaning you can only drive a vehicle fitted with an approved alcohol interlock device. The minimum period is six months, but it can run much longer for repeat offences, and the length is set by the Magistrates' Court or VicRoads based on your driving history.

During this time, every trip is recorded. The interlock camera captures an image whenever the driver blows into the device, and it also records all failed and refused breath tests, which are logged in your AIMS account.

Eligibility for Alcohol Interlock Removal

Before you can apply to have your alcohol interlock device removed, two things need to line up.

1. You need to have held a current licence for at least the full length of your mandated 'I' condition

2. You need a clean compliance record across a minimum number of months, exactly what the program calls "interlock usage data".

According to the official Victorian Alcohol Interlock Program rules, your first month is treated as a learning month, where you won't be penalised while you get used to using the device. From there, a month only counts toward your progress if you take every breath test the interlock requests, record no confirmed violations, and drive the vehicle at least twice.

If you tick those boxes, you're building real progress. If you don't, the clock resets.

The Five Month Rule Explained

This is where most people get tripped up. If a failed reading or violation does get recorded against your alcohol interlock, you don't just lose that one month; you need to start again and collect at least another five violation-free months before you're eligible to apply for removal.

The good news is those five months don't have to run back-to-back without a single hiccup elsewhere in your program. But there's a catch: if you don't drive at all for six months or more, you'll need to start collecting your five months of interlock data again from scratch. In other words, leaving the car parked for half a year to "wait it out" backfires badly.

Common violations to watch for include:

• Blowing a reading of 0.02 or higher

• Refusing a requested breath test

• Tampering with the device

• Leaving your car idling unattended

• Using alcohol-based hand sanitiser right before a test

• Disconnecting the battery for 20 minutes or more 

  
  

Can I Drive a Work Vehicle Without an Interlock Device?

No. The 'I' condition is attached to your licence, not to a specific car, so it doesn't matter whose vehicle you're behind the wheel of. If you don't have an approved alcohol interlock device fitted to that vehicle, you can't legally drive it. Driving any vehicle without the required interlock during your condition period is a serious offence in its own right, separate from your original conviction.

If your job genuinely requires you to drive multiple vehicles, talk to us about your options before this becomes a problem rather than after.

Do You Need a Behaviour Change Program Before Removal?

If your original offence required you to complete an Intensive Drink and Drug Driver Program, removal isn't just about clean months. You'll also need to complete a 2-hour Pre-Interlock Removal behaviour change program before VicRoads approves your application. We'd recommend booking this at least 6 weeks before your interlock period is due to end, so it doesn't delay your application once you're otherwise eligible.

Some drivers were also required to provide a licence eligibility order application earlier in the process. If you're unsure whether this affects your removal timeline, it's worth checking before you apply.

What About an Interlock Exemption?

A small number of drivers may qualify for an alcohol interlock exemption instead of completing the standard program, generally where a documented medical condition makes using the device impossible or if your offence occurred before 2014. This requires a proper alcohol assessment and supporting evidence, and most applicants still end up completing some form of drink driver program along the way.
