Drink Driving in Western Australia — What You Need to Know Right Now
Do You Need a Lawyer?
You should treat a drink driving charge in Western Australia as seriously as any criminal charge — because it is one. Even a first offence can result in a criminal conviction, mandatory licence disqualification, and fines that reach into the thousands. Without a lawyer, most people plead guilty without understanding whether there are grounds to challenge the charge, whether a Section 10 equivalent under WA law (a spent conviction order under the Spent Convictions Act 1988) might apply, or whether the police followed the correct breath or blood testing procedures.
You absolutely need a lawyer if: - Your BAC was 0.08 or above (mid or high range), as custodial sentences and longer disqualifications become live possibilities - This is not your first drink driving offence in WA — repeat offences carry mandatory minimum disqualification periods and the court has less discretion - You are a professional driver, nurse, teacher, or hold any licence or registration that a criminal conviction could destroy - You refused a breath test or blood test, which is itself a serious offence under the Road Traffic Administration Act - You were involved in an accident while over the limit - You were charged with a drink driving offence while driving unlicensed or disqualified
The consequences of not having legal representation are real: people routinely receive harsher disqualification periods, miss opportunities to have charges withdrawn due to procedural errors, and fail to present mitigating factors the Magistrate could have considered. The Magistrates Court of Western Australia moves quickly — your window to prepare is short. Call 1800 951 176 now and speak to a lawyer tonight.
The Law in Western Australia
Drink driving in Western Australia is primarily prosecuted under the Road Traffic Act 1974 and administered through the Road Traffic (Administration) Act 2008. The relevant offence is driving with a blood alcohol concentration (BAC) above the prescribed limit, and the law creates a tiered penalty system based on how far over the limit you were and whether you are a first or repeat offender.
The prescribed limits in WA are: 0.05 BAC for full licence holders; 0.02 BAC for holders of a vehicle licence with a condition (such as an interlock condition); and zero BAC for learner drivers, provisional licence holders, and drivers of heavy vehicles, taxis, and certain other vehicles.
WA Police are authorised under the Road Traffic Administration Act to conduct random breath testing (RBT) and to require a driver to undergo a breath analysis at a police station if a preliminary test indicates alcohol presence. A blood test may also be required in certain circumstances, including where a breath test is not possible. Refusal to submit to a breath or blood test is a standalone offence under section 67 of the Road Traffic Administration Act and carries penalties comparable to a mid-range drink driving offence.
When charged, WA Police can issue an immediate licence suspension notice — meaning your licence is suspended on the spot before any court hearing. Your matter is then listed in the Magistrates Court of Western Australia, which has jurisdiction over all summary drink driving offences. Matters are typically heard within four to eight weeks of being charged in metropolitan Perth courts, though regional WA courts such as those in Bunbury, Geraldton, Kalgoorlie, and Broome may have different timelines.
For serious offences — including high-range readings above 0.15 BAC, dangerous driving involving alcohol, or matters connected to serious injury — charges may be escalated or additional charges laid under the Road Traffic Act. The court has powers to impose fines, mandatory disqualification, interlock orders, and imprisonment. Mandatory alcohol interlock conditions apply to many offenders upon licence restoration under the Road Traffic (Authorisation to Drive) Regulations 2014.

What Happens Next — Step by Step
1
Step 1 — Do not make any further statements to police: If you have already been charged and released, do not contact WA Police to explain yourself or provide additional information. Anything you say can be used against you in the Magistrates Court of Western Australia. Your right to silence exists and you should exercise it.
2
Step 2 — Call Legal Hotline immediately on 1800 951 176: Our lawyers are available 24 hours a day, 7 days a week. Tell them exactly what happened, what reading you were given, what documents police gave you, and whether your licence was suspended on the spot. The earlier you call, the more options you have.
3
Step 3 — Locate and keep all documents police gave you: You should have received a Notice to Appear or a charge sheet, and possibly an immediate licence suspension notice. Note the court date, the court location (e.g. Perth Magistrates Court, Fremantle Magistrates Court), and the exact charges listed. Do not miss your court date — a warrant can be issued in your absence.
4
Step 4 — Gather all relevant information about the incident: Write down everything you remember — where you were, what you consumed and when, what the police said and did, whether you were offered a blood test, and whether the roadside and station readings matched. Details about the testing procedure can be legally significant in WA.
5
Step 5 — Attend court with legal representation and a mitigation plan: Even if you intend to plead guilty, a lawyer can present your personal circumstances, employment, family situation, and any steps you have taken (such as seeking counselling) to the Magistrate. This can directly influence whether you receive a lesser disqualification period, a fine rather than imprisonment, or a spent conviction under the Spent Convictions Act 1988 (WA).
Mistakes to Avoid
⚠️
Pleading guilty at the first mention without legal advice: Many people appear at the Magistrates Court of Western Australia on their first mention date and plead guilty immediately, believing it will be resolved quickly. This is a critical error — it eliminates any chance to challenge the charge, identify procedural errors in the breath testing process, or explore whether the charge can be reduced or withdrawn. A one-week adjournment to get legal advice costs nothing and can change everything.
⚠️
Assuming a low BAC reading means a minor outcome: A reading of 0.06 or 0.07 is still a criminal charge in WA and results in a mandatory licence disqualification even for first offenders. People underestimate how seriously the Magistrates Court treats even low-range drink driving, particularly when their occupation depends on driving. The impact on employment, insurance, and travel visas is often not considered until after the conviction is recorded.
⚠️
Ignoring the immediate licence suspension and continuing to drive: WA Police issue immediate licence suspension notices on the spot, and driving on a suspended licence is a separate and serious criminal offence under the Road Traffic Administration Act 2008. Some people mistakenly believe they can drive until their court date — they cannot. Being caught driving while suspended compounds your original charge significantly and can result in imprisonment.
⚠️
Not challenging the accuracy or procedural legality of the breath test: In WA, the breath analysis process must comply with strict procedural requirements under the Road Traffic Administration Act 2008. Errors in calibration records, failure to observe the required observation period before testing, or improper administration of the test can provide grounds to challenge the reading. Without a lawyer reviewing the prosecution brief, these opportunities are missed entirely.
Likely Outcomes
The outcome of a drink driving charge in Western Australia depends primarily on your BAC level, whether it is a first or repeat offence, and the specific circumstances of the offence. Here is an honest picture of what the Magistrates Court of Western Australia typically imposes:
For a first offence at low range (0.05–0.079 BAC), you can expect a fine typically between $500 and $1,500, a mandatory licence disqualification of at least six months (though the court can reduce this with strong mitigation), and the possibility of a spent conviction under the Spent Convictions Act 1988 if circumstances support it.
For a first offence at mid range (0.08–0.149 BAC), fines increase substantially — commonly $1,500 to $3,000 — and disqualification periods extend to a minimum of seven months to over a year. An alcohol interlock condition is frequently imposed on licence restoration under WA's interlock scheme.
For a high-range offence (0.15 BAC or above) or a repeat offence within ten years, imprisonment becomes a real possibility. WA courts impose mandatory minimum disqualification periods of two years or more for repeat offenders, and fines can reach $5,000 or higher. A mandatory alcohol interlock requirement on licence restoration is effectively guaranteed.
Refusal to undergo a breath or blood test is treated as seriously as a mid to high-range offence. All drink driving convictions in WA are recorded on your criminal history and reported to the Department of Transport, affecting your driving record permanently unless a spent conviction order is obtained.
First offence, low range (0.05–0.079 BAC)
Fine $500–$1,500 | Licence disqualification minimum 6 months | Possible spent conviction under Spent Convictions Act 1988 (WA) | No mandatory interlock for first low-range offence
First offence, mid range (0.08–0.149 BAC)
Fine $1,500–$3,000 | Disqualification 7–12+ months | Alcohol interlock condition likely on restoration | Criminal conviction recorded unless spent conviction granted
High range (0.15+ BAC) or repeat offender
Fine up to $5,000+ | Disqualification 2+ years (mandatory minimums apply) | Mandatory alcohol interlock on restoration | Imprisonment a real risk | No spent conviction available for repeat offences
Refusal to submit to breath or blood test
Treated as mid to high-range equivalent | Significant fine and disqualification | Criminal conviction recorded | Magistrates Court of WA has limited discretion to reduce penalties for refusal
Legal Aid in Western Australia
Legal Aid Western Australia (Legal Aid WA) is the body that provides government-funded legal assistance for eligible Western Australians facing criminal charges, including drink driving. Legal Aid WA can be contacted on 1300 650 579 and their offices are located in Perth and major regional centres including Bunbury, Geraldton, Kalgoorlie, and Broome.
However, you need to be honest about what Legal Aid WA can and cannot do for drink driving matters. Eligibility for funded representation is means-tested and merit-tested, and Legal Aid WA often does not fund representation for first-offence summary drink driving charges where there is no realistic prospect of imprisonment. This means many people facing drink driving charges in WA do not qualify for a funded lawyer.
Legal Aid WA does operate a duty lawyer service at Perth Magistrates Court and some regional courts, and a duty lawyer may be able to provide brief advice on the day of your court appearance — but this is not the same as full representation, and duty lawyers have very limited time to review your matter.

Frequently Asked Questions — Drink Driving in Western Australia
What are the drink driving BAC limits in Western Australia?
In Western Australia, the prescribed BAC limit is 0.05 for most full licence holders, 0.02 for drivers with a conditioned licence (such as an interlock condition), and 0.00 (zero) for learner drivers, provisional licence holders, and drivers of heavy vehicles, taxis, and certain other vehicle classes. These limits are set under the Road Traffic Act 1974 (WA). Exceeding any of these limits while driving constitutes a criminal offence that will be prosecuted in the Magistrates Court of Western Australia. If you are unsure which limit applies to your licence, call 1800 951 176 now.
Can WA Police suspend my licence on the spot before I go to court?
Yes — WA Police have the power to issue an immediate licence suspension notice on the spot under the Road Traffic Administration Act 2008 (WA). This means your licence is suspended from the moment you receive that notice, regardless of whether you have been convicted of anything. You cannot legally drive until the matter is resolved or the suspension is lifted. Driving on an immediately suspended licence is a separate criminal offence that can result in additional charges, fines, and imprisonment. If you have received an immediate suspension, call 1800 951 176 immediately for advice on your rights.
What happens if I refused a breath test in Western Australia?
Refusing a breath or blood test in Western Australia is a serious criminal offence under section 67 of the Road Traffic Administration Act 2008 (WA). The penalties are equivalent to or exceed those for a mid to high-range drink driving offence and include significant fines and mandatory licence disqualification. Police in WA are authorised to require a breath test at roadside and a breath analysis at a police station; refusal at either stage can be charged. There is very limited legal justification for a refusal that courts will accept. If you have refused, you need urgent legal advice — call 1800 951 176 now.
Will a drink driving conviction in WA appear on my criminal record?
Yes, a drink driving conviction in Western Australia is a criminal conviction and will appear on your criminal history unless a spent conviction is granted under the Spent Convictions Act 1988 (WA). A Magistrate has discretion to impose a spent conviction for first offences in limited circumstances, which means the conviction is not disclosed after a ten-year period for most purposes. However, spent convictions are not guaranteed and are not available for repeat offenders. A conviction can affect employment, professional licensing, immigration status, and overseas travel. Getting legal advice before you plead is critical to maximising your chances of a spent conviction.
What is the minimum licence disqualification for drink driving in WA?
In Western Australia, the minimum licence disqualification for a first drink driving offence at low range (0.05–0.079 BAC) is six months, though the Magistrates Court has some discretion based on mitigating circumstances. For mid-range first offences the minimum is around seven months. For high-range or repeat offences, mandatory minimum disqualification periods apply and extend to two years or more. These minimums are set under the Road Traffic Act 1974 (WA) and cannot be reduced below the statutory floor regardless of your circumstances. Legal representation can help ensure you receive the minimum rather than a longer period.
What is the alcohol interlock program in Western Australia and will it apply to me?
Western Australia's alcohol interlock program requires eligible offenders to have an approved interlock device fitted to their vehicle as a condition of licence restoration after disqualification. The program is administered by the Department of Transport WA under the Road Traffic (Authorisation to Drive) Regulations 2014 (WA). It typically applies to mid and high-range first offenders, all repeat offenders, and those with high BAC readings at first offence. The interlock must remain fitted for a mandatory period — often 12 months or more — and all costs are borne by the offender. Breaching an interlock condition is a criminal offence. A lawyer can advise whether the interlock applies to your specific charge.
Which court will hear my drink driving charge in Western Australia?
Drink driving charges in Western Australia are heard in the Magistrates Court of Western Australia, which handles all summary criminal offences including road traffic matters. In the Perth metropolitan area, matters are typically listed at Perth Magistrates Court on Hay Street or at suburban courts including Fremantle, Joondalup, Midland, and Armadale. In regional WA, cases are heard in Magistrates Courts in cities such as Bunbury, Geraldton, Kalgoorlie, Albany, and Broome. The court date is printed on your Notice to Appear. You must attend — if you do not appear, a warrant for your arrest may be issued.
Can I challenge a breath test result in Western Australia?
Yes, it is possible to challenge a breath test result in Western Australia, though success depends on the specific facts of your case. Challenges are typically based on procedural grounds — for example, whether the required observation period before testing was followed, whether the evidentiary breath analysis device was properly calibrated, or whether the test was administered in compliance with the Road Traffic Administration Act 2008 (WA). The prosecution must produce evidence of the device's accuracy and the officer's compliance with procedure. A lawyer can request the prosecution brief and assess whether there are grounds for challenge. Call 1800 951 176 to discuss whether this is available in your matter.
I was charged with drink driving in a regional area of WA — does the same law apply?
Yes, the same Western Australian legislation applies statewide — the Road Traffic Act 1974 (WA) and the Road Traffic Administration Act 2008 (WA) govern drink driving offences in all parts of WA, including regional and remote areas. However, regional courts such as those in Kalgoorlie, Geraldton, Broome, and Port Hedland may have different listing timelines, and accessing legal representation in some areas can be more difficult. Legal Hotline operates 24/7 for all of Western Australia regardless of location — call 1800 951 176 and a lawyer will help you regardless of where in WA you are located.
I need to drive for work — will I lose my licence for drink driving in WA?
Needing your licence for work does not exempt you from the mandatory licence disqualification that applies to drink driving convictions in Western Australia. Unlike some other jurisdictions, WA does not currently offer a work licence or restricted licence scheme that allows disqualified drink drivers to continue driving for employment purposes. Mandatory disqualification under the Road Traffic Act 1974 (WA) applies regardless of employment need. However, a lawyer can present your employment situation as a mitigating factor when the Magistrate considers the length of disqualification, and in some cases this may influence the outcome. Call 1800 951 176 to discuss your specific circumstances.
