Drink Driving Penalties in Tasmania: Ranges, Fines, Licence Loss and the Interlock

By James Stevens, Director and Solicitor, Go To Court Lawyers. Last reviewed 20 April 2026.

In Tasmania, a first drink-driving offence at a reading of 0.05 to under 0.1 carries a court fine of $426 to $2,130, up to 3 months' jail, or both, and a disqualification of 3 to 12 months, or police may instead give an infringement notice of $426 with 3 months off the road.

Checked on 22 October 2026 against the Road Safety (Alcohol and Drugs) Act 1970 and its Regulations 2018, the Vehicle and Traffic Act 1999, the Sentencing Act 1997, the Monetary Penalties Enforcement Act 2005, the Government's penalty unit and interlock program pages, the Magistrates Court's restricted licence form and Tasmania Legal Aid.

The limit and the bands

Tasmania has no 0.08 band. A reading of 0.08 or 0.09 is in the lowest band, 0.05 to under 0.1. Driving under the influence is a separate offence that needs no reading: driving while so affected by alcohol or a drug that you cannot properly control the vehicle.

Court penalties

Fines in Tasmania are set in penalty units. The dollar figures on this page use $213 a unit, the value from 1 July 2026 to 30 June 2027.

• The court must impose a fine within the range, jail up to the maximum, or both, and must disqualify you for a period within the range.
• Special circumstances: if you satisfy the court that there are special circumstances, it may impose a lower fine or a shorter disqualification than the minimum. The law sets no floor. Jail has no minimum.
• There is no third-offence tier: every offence after the first uses the second-offence column.
• Your licence: a disqualification of 4 months or less suspends it; a longer one cancels it.
• One occasion of driving counts as one conviction, even if you are convicted of more than one offence for it.
• Refusing the roadside breath test (as opposed to the breath analysis that follows) carries up to $2,130 or 6 months' jail, and the court may disqualify you for up to 3 years.

Infringement notices (first readings under 0.15)

• Police may give an infringement notice instead of charging you for a reading of 0.05 to under 0.15. It is their choice.
• 0.05 to under 0.1: 2 penalty units ($426) and 3 months' disqualification. 0.1 to under 0.15: 4 penalty units ($852) and 6 months' disqualification.
• Not available if you have ever been convicted of an offence under the drink-driving Act, or of manslaughter involving driving or a dangerous-driving offence, or if you were driving a prescribed vehicle (such as a bus or other passenger transport vehicle, a goods vehicle over 4.5 tonnes or a dangerous-goods vehicle). Whether a learner or P-plater can be given one is not clear from the regulations.
• Court only: 0.15 or more, driving under the influence, any refusal, and a zero-alcohol reading under 0.05.
• Electing court: you have 28 days from when the notice is served to lodge a notice of election to go to court, or to ask for the notice to be withdrawn. If you pay, or do nothing in that time, you are taken to have been convicted, and you are sent a notice of disqualification.
• A restricted licence can still be applied for after a disqualification by infringement notice, if you are eligible (see below).

On-the-spot disqualification

• Police may disqualify you on the spot (a road safety disqualification notice) if they believe on reasonable grounds that you drove under the influence; had a reading of 0.15 or more (0.07 or more if you do not hold a full licence, which includes learners and P-platers); refused a breath analysis or blood test; or committed what would be your second or later offence.
• How long: until the court deals with the charge, or until the minimum disqualification for that offence has passed, whichever comes first. For a first offence at 0.15 or more, driving under the influence or a refusal, that minimum is 12 months; for a learner or P-plater it is 3 months at 0.07 to under 0.1 and 6 months at 0.1 to under 0.15.
• Credit: the court must take the time you have served into account when it sentences you.
• Challenging it: you can appeal to the Magistrates Court on the ground that the notice will cause you severe and unusual hardship, or that there are other special circumstances, giving 14 days' written notice to the Commissioner of Police and a registrar. The court hearing the charge, or the Commissioner, can also cancel the notice.
• No restricted licence can be granted while the notice is running.

Restricted licences

• Tasmania has a restricted licence. If your licence is, or will be, suspended or cancelled for drink driving (by a court or by an infringement notice), you can ask the Magistrates Court for one.
• The test: that losing your licence would cause severe and unusual hardship to you or your dependants, which a restricted licence would relieve, and that granting it would not be contrary to the public interest. Alcohol dependency counts as contrary to the public interest, and the court may want a doctor's evidence.
• Not available if the reading was 0.15 or more; for driving under the influence; for refusing a breath analysis or blood test, or objecting to blood analysis; if you held a learner or provisional licence; if you were not licensed for the vehicle; if you were driving a prescribed vehicle; or if the offence was committed during, or within 3 years after, a disqualification under the drink-driving Act. In practice, that leaves full licence holders under 0.15 with no recent disqualification.
• How to apply: a written application in the form of a statutory declaration, served on the Registrar and the nearest Police Prosecutions office at least 7 days before the hearing. The court charges a filing fee.
• Conditions: the court sets the vehicles, days, hours and routes, and may require a log book; you must have no alcohol at all in your body when you drive. If it grants a restricted licence, the court may also extend the disqualification by up to the period still to run.
• Breaching it carries up to $8,520 or 6 months' jail, and $17,040 or 12 months for a later breach.

The alcohol interlock

• Who: the Government's Mandatory Alcohol Interlock Program applies to anyone convicted of driving under the influence, a reading of 0.15 or more, two or more drink-driving offences in five years, or failing to give a breath or blood specimen for analysis.
• How it works: after the disqualification your licence carries an interlock condition (the "I-condition"). You may drive only a vehicle fitted with an approved interlock, you blow into it every time you start the car and again while driving, your reading must be zero, and the device must be serviced regularly.
• How long: at least 15 months, a 9-month learning period and a 6-month demonstration period. To finish, you must record no lockouts in the demonstration period (the last 180 days).
• Cost: the Government estimates about $3,000 to $3,500.

Refusing a test

• Refusing a breath analysis, or a blood test after a crash causing injury, or objecting to the analysis of your blood sample, carries the high-range penalties: $1,065 to $6,390, up to 12 months' jail, or both, and 12 to 36 months' disqualification for a first offence. Police may disqualify you on the spot, the interlock program follows, and no restricted licence is available. Tasmania Police says a refusal "carries the same serious consequences as high-range drink driving offences".
• The defence is a reasonable excuse. A medical condition is an excuse for not giving breath only if it would also stop you giving blood.
• Refusing the roadside breath test is a lesser offence: up to $2,130 or 6 months' jail, and the court may disqualify you for up to 3 years. Police can then require a breath analysis.

How the test is done

• Police can require a breath analysis or blood test within 5 hours of your last driving.
• The limit is 0.05 grams of alcohol in 210 litres of breath, or in 100 millilitres of blood.

How earlier offences are counted

• No time limit: an earlier conviction for driving under the influence, driving over the limit, drug driving, or refusing or objecting to a test makes a new offence a second or later offence, however long ago it was.
• Other time windows: the interlock program looks at two offences in five years; the restricted licence bar at an offence within 3 years after a disqualification ends; and the zero-alcohol rule applies to anyone with 3 or more convictions under the Act from 3 occasions within 10 years.
• An infringement notice is not available to anyone with an earlier conviction under the drink-driving Act, however old.

No conviction recorded

The Sentencing Act 1997 lets a court deal with many offences without recording a conviction, weighing the offence, your character and your employment prospects, and such a finding is not a conviction for any purpose unless another law says so. But that power is subject to laws dealing specifically with an offence, and the drink-driving penalties bind "a court that convicts". Whether a drink-driving charge can end without a conviction, and whether the disqualification would then apply, is not settled by the sources checked for this page, so get advice before you rely on it.

Getting your licence back, and driving while disqualified

• Reapplying: if your licence was cancelled (a disqualification over 4 months), you apply for a new licence when the disqualification ends, and it is a probationary licence. The interlock condition follows where the program applies.
• Driving while disqualified carries up to $8,520 or 6 months' jail, or both, and up to 3 more years' disqualification; for a later offence, up to $17,040 or 12 months, or both, and up to 5 more years.
