Refusing the breath or blood test in Ireland: an offence in its own right

Refusing or failing to provide a specimen when a Garda lawfully requires one is an offence in Ireland, separate from drink or drug driving and in most cases punished more heavily. This guide explains what the Road Traffic Act 2010 requires, what counts as a refusal, the defence the Act allows, what follows a refusal charge in the District Court, and what the court looks at. It does not tell you how to refuse, because there is no way to do so that is not an offence.

What the Act requires

The Road Traffic Act 2010 gives the Garda the power to require specimens at two points.

At the roadside. At a mandatory intoxicant testing checkpoint, where the Garda has formed an opinion that you have consumed alcohol or taken a drug, or after a collision, the Garda can require a preliminary breath specimen into a handheld device and, since the Road Traffic Act 2016, an oral fluid specimen for drugs. You must provide it. Refusing, or failing to provide it in the way the Garda directs, is an offence carrying a fine of up to €5,000 and/or up to six months, and the Garda can arrest you.

At the station. After arrest, the Garda can require you to provide two specimens of breath on the station apparatus, or a specimen of blood taken by a designated doctor or nurse, or, at your option in place of blood, a specimen of urine. The Garda tells you the requirement and the consequences of refusing. Refusing or failing to provide the specimen is the offence most people mean when they search this question, and it is the one that carries the mandatory disqualification.

What counts as a refusal

The Act treats refusing and failing alike. In practice a refusal charge follows where a person:

• says no;
• does not blow into the apparatus in the way the Garda directs, so that it cannot record a reading, where the Garda forms the view this was deliberate;
• agrees to give blood and then does not let the doctor or nurse take it;
• agrees to give urine and does not provide it within the time allowed;
• is obstructive or leaves the room when the requirement is made.

An incomplete breath specimen is treated as a failure unless there was a medical reason the court accepts. The apparatus records the attempt, and the Garda gives evidence of what happened.

The defence the Act allows

The Act provides a defence where the person shows there was a special and substantial reason for the refusal or failure, and that, as soon as practicable after the reason arose, they offered to provide a specimen of another kind that the Garda could have required. In the cases where it succeeds, it rests on medical evidence: a respiratory condition that made a breath specimen impossible, a needle phobia documented before the event, a condition affecting the ability to provide urine. Saying "I have asthma" at the station without more is not what the Act means.

Where breath cannot be given for a medical reason, the Garda can require blood or urine instead. The route through a medical difficulty is to say so and give the other specimen, and that is the route the Act expects.

Drunkenness is not a special and substantial reason. Neither is the wish to speak to a solicitor first, though you can ask for one and the Garda should facilitate it within a reasonable time without the requirement being suspended.

The doctor or nurse at the station

Blood and urine specimens are taken by a designated doctor or nurse, who is called to the station. You are not examined by them unless impairment is alleged, in which case a separate medical examination may be carried out. The specimen is divided, one part sent to the Medical Bureau of Road Safety and one offered to you, and the Bureau's certificate of analysis is the evidence. Refusing to let the doctor or nurse take the specimen after agreeing to it is a refusal.

What follows a refusal

A refusal at the station is charged under the 2010 Act and goes to the District Court on a summons or a charge sheet. The Road Traffic Act 2010, section 65, fixes a minimum disqualification of four years for a first offence and six years for a second or later offence, the same as driving while incapable of proper control. The figure is the one in the Citizens Information account of the Act, and this site flags it for verification against the current text. The court can also impose a fine of up to €5,000 and/or up to six months in custody. A conviction is a criminal record.

For comparison, a reading over the limit carries a minimum of six months to three years for a first offence depending on the band. For almost every reading, a refusal is the heavier outcome. The disqualification periods guide sets out the table.

A refusal does not end the drink driving case. Without a reading the Garda cannot charge driving over the limit, but they can and do charge driving while incapable of proper control under section 4(1), on their observations of the driving and of your condition, and the two charges can be heard together. In that case there are two mandatory disqualifications in play.

There is no fixed penalty notice for a refusal.

What the court looks at

On a guilty plea the Garda outlines the facts and you or your solicitor speak in mitigation. The things the court weighs are the ones it weighs on any road traffic charge: a plea at the first opportunity, your record, the circumstances of the stop, cooperation otherwise, your work and family and what a four-year disqualification means, and steps taken since. The court cannot go below the minimum for any of them; they bear on the fine, on custody and on whether the court goes above four years.

On a not guilty plea the hearing turns on the evidence from the station. The prosecution has to show that the Garda lawfully required the specimen, told you what was required and what would follow a refusal, and that you refused or failed. The defence, where there is one, is the special and substantial reason, and the court hears the medical evidence for it. That is work for a solicitor with the custody record and the station CCTV, which can be sought by a disclosure request once a not guilty plea is entered.

Legal aid

A refusal charge carries a risk of custody and a four-year disqualification, which meets the gravity test under the Criminal Justice (Legal Aid) Act 1962. If your means are insufficient, complete a statement of means and ask the judge for legal aid at the first appearance, before anything else is dealt with. The legal aid check applies the two tests.

The figures

The Courts Service Annual Report 2025, published on 13 July 2026, counts refusal charges within the 9,784 drink and drug driving orders made in the District Court, which included 3,663 disqualifications and 100 sentences of imprisonment. A separate figure for refusals is not published.

Afterwards

The disqualification takes effect from the fifteenth day after the order unless you appeal within fourteen days and enter the recognisance, which stays it until the Circuit Court decides. After the period you apply to the NDLS (see the glossary) for a new licence; the court may have ordered a driving test first, and where the disqualification is two years or more an application for early removal can be made after half of it has run. See getting your licence back. The conviction and insurance afterwards are covered in is drink driving a criminal record and car insurance after a drink driving conviction.

Where this leaves you

The drink and drug driving checker shows the minimum disqualification the Act fixes for a refusal and the fine and custody the court can impose, and the court date tool counts the days to the summons date and the appeal window. Find a court gives you the office.

If you may qualify for legal aid, ask the judge for it at your first appearance. A refusal charge is one most people do not face without a solicitor. The support page lists services if the night at the station has left you struggling.
