Legal context
Drink driving offences in Northern Ireland are primarily governed by the Road Traffic (Northern Ireland) Order 1995, which sets the legal alcohol limit at 35 micrograms per 100ml of breath, 80 milligrams per 100ml of blood, or 107 milligrams per 100ml of urine. The Police Service of Northern Ireland (PSNI) has powers to conduct roadside breath tests and arrest drivers who fail or refuse testing. Prosecutions are brought by the Public Prosecution Service (PPS) in the Magistrates' Court NI, though serious cases involving injury or repeat offences may be heard in the Crown Court NI. Penalties include a minimum 12-month driving ban, fines up to £5,000, and up to 6 months' imprisonment, with enhanced penalties for high readings or aggravating factors.

At a glance
Northern Ireland's drink drive limit is 35mcg per 100ml of breath, identical to England and Wales. The PSNI can require a breath test if they suspect alcohol consumption, after a moving traffic offence, or following an accident. Refusing to provide a specimen is a separate offence carrying the same penalties as drink driving itself.
Most drink driving cases are heard in the Magistrates' Court NI, with the PPS presenting evidence including breath test results and witness statements. Convicted drivers face a minimum 12-month ban (reduced by 25% if completing an approved course), fines based on income, and possible imprisonment. The disqualification period increases for repeat offenders or high readings.
Potential defences include procedural errors in the testing process, medical conditions affecting readings, or the 'hip flask' defence where alcohol was consumed after driving. Special reasons not to disqualify might include genuine emergencies or unknowingly consuming alcohol. Expert legal representation is crucial as these arguments require careful presentation to succeed.

Common questions
The PSNI will conduct a roadside breath test using an approved device. If you fail or refuse, you'll be arrested and taken to a police station for an evidential breath, blood or urine test. You have the right to legal advice before providing the evidential sample. The results will determine whether you're charged, with proceedings typically starting in the Magistrates' Court NI within weeks.
A driving disqualification is mandatory for drink driving convictions unless 'special reasons' apply. These are exceptional circumstances like genuine emergencies or unknowingly consuming alcohol, but they're difficult to establish. The court has no general discretion to avoid imposing a ban. However, completing a drink drive rehabilitation course can reduce the disqualification period by up to 25%.
Failing to provide a specimen when required by the PSNI is a separate offence carrying the same penalties as drink driving - minimum 12-month ban and up to £5,000 fine. The PPS must prove you refused without reasonable excuse. Medical conditions like asthma might provide a defence, but you'll need medical evidence to support this claim in court.
Many employers require notification of criminal convictions, and driving bans can lead to dismissal if driving is essential to your role. Professional drivers face particular difficulties, and some professions have mandatory reporting requirements. The conviction will appear on criminal record checks for 5 years. An experienced solicitor can advise on minimising employment impacts and presenting mitigation to the court.
No, driving disqualifications imposed by Northern Ireland courts are recognised throughout the UK and Ireland under mutual recognition agreements. Driving whilst disqualified is a serious offence that can result in imprisonment. The Common Travel Area arrangements don't affect driving ban enforcement, and you risk arrest if caught driving anywhere on the island of Ireland.
The PPS must prove you were driving or in charge of a vehicle on a public road with alcohol exceeding the legal limit. The main evidence is usually the breath test reading from the evidential machine at the police station. They must also show proper procedures were followed, including the 20-minute observation period. Any procedural failures could invalidate the evidence.
Most drink driving cases in the Magistrates' Court NI conclude within 2-4 months from the offence date. The first appearance is usually within 4-6 weeks, where you'll enter a plea. Guilty pleas are sentenced immediately or after reports. Not guilty pleas result in a trial date being set, typically 2-3 months later, when the PPS must prove their case.
Yes, you can appeal to the County Court NI against conviction or sentence within 21 days. The appeal is a complete rehearing of the case before a County Court judge. You can also appeal on points of law to the High Court NI by way of case stated. Legal advice is essential as appeals must identify specific grounds and follow strict procedures.
