Drink Driving Laws in the UK: What You Need to Know

Drink driving offences are among the most common road traffic cases in the UK, but many people don’t fully understand the law—or the serious consequences that can follow a conviction.

In this article, we explain the key facts about drink driving laws, the legal alcohol limits, possible penalties, and how a solicitor can help if you’re facing charges.


What Is Drink Driving?

Drink driving is when a person drives (or attempts to drive) a vehicle on a road or public place after consuming alcohol in excess of the legal limit.

The law doesn’t only apply if you’re caught driving erratically—being “over the limit” is enough to commit the offence, even if you believe you’re in full control of your vehicle.


What Are the UK Drink Driving Limits?

The alcohol limit depends on whether you’re in England, Wales, Northern Ireland or Scotland:

  • England, Wales and Northern Ireland:

    • 35 micrograms of alcohol per 100ml of breath

    • 80 milligrams of alcohol per 100ml of blood

    • 107 milligrams of alcohol per 100ml of urine

  • Scotland (stricter limits):

    • 22 micrograms of alcohol per 100ml of breath

    • 50 milligrams of alcohol per 100ml of blood

    • 67 milligrams of alcohol per 100ml of urine

It’s important to remember that alcohol affects everyone differently. Age, weight, gender, food intake and even stress can change how your body processes alcohol. There’s no safe way to calculate “how much you can drink and still drive.”


What Are the Penalties for Drink Driving?

Drink driving carries severe penalties. The exact sentence depends on the circumstances, but common consequences include:

  • Driving or attempting to drive while over the limit:

    • At least 12 months’ driving ban (3 years if convicted twice in 10 years)

    • Unlimited fine

    • Up to 6 months in prison

  • Being in charge of a vehicle while over the limit:

    • 3 months in prison

    • Up to £2,500 fine

    • Possible driving ban

  • Causing death by careless driving while under the influence:

    • Up to 14 years in prison

    • Unlimited fine

    • Minimum 2-year driving ban and extended retest

In addition, a conviction will go on your criminal record and can impact employment, insurance costs, and travel abroad.


Police Powers and Drink Driving Tests

If the police suspect you’ve been drinking, they can stop you and require a breath test at the roadside.

If you fail (or refuse) this test, you’ll be taken to a police station for further tests, including blood or urine samples if necessary.

Refusing to provide a specimen without reasonable excuse is itself a criminal offence, carrying penalties similar to drink driving.


Can You Defend a Drink Driving Charge?

Every case is different, and while drink driving is taken extremely seriously, there are situations where a defence may apply. Examples include:

  • Procedural errors – if the police didn’t follow correct procedure.

  • Medical conditions – certain conditions (e.g. asthma) may affect breath test results or ability to provide a specimen.

  • Post-driving consumption – where alcohol was consumed after driving but before testing.

A solicitor can also argue “special reasons” (such as driving in a genuine emergency) to help reduce or avoid a disqualification.
