Being stopped by the police and asked to take a breathalyser test can be an intimidating experience, especially if you are unsure of your rights or the potential consequences of refusal.

Is it Illegal to Refuse a Breathalyser Test in the UK?
Yes — under section 7 of the Road Traffic Act 1988, it is a criminal offence to refuse to provide a specimen of breath, blood or urine when lawfully required to do so by the police. This applies whether you are tested at the roadside or at a police station.
Common Situations Leading to a Request for a Specimen:
- Being stopped by police on suspicion of drink driving.
- Being involved in a road traffic accident.
- Being stopped at a random roadside breath test checkpoint.
Are There Any Lawful Excuses for Refusing?

You may have a reasonable excuse for not providing a specimen. Examples include:
- Medical conditions such as asthma, chest infections or panic attacks making it physically impossible to blow into the device.
- Mental health conditions affecting your ability to comply.
- A genuine inability to understand the instructions, for example due to language barriers (if not addressed by the police).
The courts require credible evidence of any such excuse, which is why specialist legal representation is crucial.
What Are the Penalties for Refusing a Breathalyser Test?
The penalties can be severe and may include:
- Driving disqualification – Minimum 12 months for a first offence, and at least 3 years if you have a prior relevant conviction.
- Unlimited fine – The amount depends on your income.
- Imprisonment – Up to 6 months in serious cases.
- Criminal record – This can affect employment, travel and future opportunities.
In many cases, the punishment for refusal is the same or greater than if you had taken the test and been found over the limit.
How We Can Help You Avoid Conviction

In many “fail to provide” cases, we can:
- Challenge whether the police followed correct procedure when requesting the specimen.
- Prove that you had a genuine and reasonable excuse.
- Identify technical issues with the testing equipment or process.
- Negotiate reduced penalties or alternative disposals.
Frequently Asked Questions: Can You Really Refuse a Breathalyser Test in the UK?
Can I refuse a roadside breath test?
You can refuse, but unless you have a reasonable excuse recognised in law, you will be arrested and face prosecution.
What happens if I fail to provide a specimen at the police station?
This is treated as a separate criminal offence, with serious penalties including a mandatory driving ban.
Is it better to refuse than to fail?
No — in most cases, refusal carries similar or even harsher penalties than a failed test.
Will I go to prison for refusing?
Prison is possible in serious cases, particularly if your driving was dangerous or you have prior convictions.
How can a solicitor help me?
