Facing a first drink driving charge in the UK? Understand the legal process, likely penalties, driving ban length, and what options may be available.
Last reviewed: 30 March 2026
Quick answer
A first drink driving offence in the UK is treated seriously and typically results in a driving disqualification of at least 12 months, an unlimited fine, and a possible prison sentence of up to 6 months. The exact outcome depends on the level of alcohol detected and the circumstances of the case.
What this means in practice
After being charged, the case will generally be listed at the Magistrates' Court. Most first-time drink driving cases are dealt with in the Magistrates' Court rather than the Crown Court. The court considers the alcohol reading, any aggravating factors such as an accident or passengers being present, and any mitigating circumstances. People found guilty of a first offence may be offered a Drink Drive Rehabilitation Course, which, if completed, can reduce the disqualification period by up to 25 percent. Insurance premiums typically increase significantly after a drink driving conviction, and the conviction remains on a driving record for 11 years.
Common situations
Common situations include: being stopped at a routine police checkpoint, being breathalysed after a minor road traffic accident, being reported by a member of the public, morning-after drink driving where alcohol from the previous evening is still in the system, and being asked to provide a blood or urine sample at the police station.
What UK law says
Drink driving is an offence under Section 5 of the Road Traffic Act 1988. The legal limit in England and Wales is 35 micrograms of alcohol per 100 millilitres of breath, 80 milligrams per 100 millilitres of blood, or 107 milligrams per 100 millilitres of urine. Section 6 of the Road Traffic Act 1988 gives police the power to require a preliminary breath test. The Road Traffic Offenders Act 1988 sets out the penalties, including mandatory disqualification of at least 12 months for a first offence. The Magistrates' Court Sentencing Guidelines classify drink driving into three bands based on the breath reading.
What people often consider
People facing a first drink driving charge often consider whether to plead guilty or not guilty, whether there were procedural errors in the breath test or blood sample process, whether they can demonstrate exceptional hardship to avoid or reduce a ban, and whether a solicitor specialising in motoring law might achieve a more favourable outcome. Some people explore whether the Drink Drive Rehabilitation Course might reduce their disqualification period. The impact on employment, particularly for those who drive for work, is often a significant concern.
Common mistakes to avoid
Common mistakes include: assuming a first offence will result in a lenient sentence (mandatory disqualification applies regardless), not seeking legal advice before the court hearing, failing to attend court which may result in being found guilty in absence with potentially harsher penalties, not understanding how morning-after alcohol can still put someone over the limit, and not checking eligibility for the Drink Drive Rehabilitation Course at sentencing.
Frequently asked questions
How long is the driving ban for a first drink driving offence?
The minimum disqualification for a first offence is 12 months, but this can be longer depending on the alcohol reading and circumstances. Completing a Drink Drive Rehabilitation Course, where offered by the court, may reduce the ban by up to 25 percent.
Will I go to prison for a first drink driving offence?
Prison is possible but uncommon for a first offence where the reading is lower and there are no aggravating factors. The maximum sentence is 6 months. Higher readings or cases involving accidents may carry a greater risk of custody.
Can I refuse a breathalyser test?
Refusing to provide a breath specimen without reasonable excuse is a separate offence under Section 7 of the Road Traffic Act 1988, carrying the same maximum penalties as drink driving itself, including mandatory disqualification.
