Quick answer
Yes. It is legal to drink alcohol-free beer and drive in the UK. A 440ml can at 0.5% ABV holds 0.22 units of alcohol, about a tenth of a normal 5% lager, and the average adult clears roughly one unit an hour. You can still be prosecuted if you are unfit to drive for any reason, so if you want zero alcohol before driving, pick a beer labelled 0.0%.

What the labels mean
UK labelling terms come from government guidance, not from drink-driving law:
- Alcohol-free: no more than 0.05% ABV. This is what 0.0% beers use.
- De-alcoholised: alcohol removed, no more than 0.5% ABV.
- Low alcohol: no more than 1.2% ABV.
Many beers sold as "alcohol-free" in the UK are 0.5%, which is the standard across most of Europe. The government has said it is exploring raising the UK alcohol-free limit to 0.5% to match. Until then, the number on the can matters more than the word on the front.
How much alcohol is in your drink?
One UK unit is 10ml of pure alcohol. Units = volume in ml × ABV ÷ 1,000.
| Drink | ABV | Serving | Units |
|---|---|---|---|
| Heineken 0.0 / Guinness 0.0 | up to 0.05% | 330 to 440ml | 0.02 or less |
| Lucky Saint Unfiltered Lager | 0.5% | 330ml | 0.17 |
| IMPOSSIBREW Enhanced Lager | 0.5% | 440ml | 0.22 |
| Regular 5% lager | 5% | 440ml can | 2.2 |
| Regular 5% lager | 5% | pint (568ml) | 2.8 |
So one can of 0.5% beer is about a tenth of one can of normal lager. The NHS says the average adult processes about one unit an hour, though this varies from person to person.
The drink-drive limits
| England, Wales and NI | Scotland | |
|---|---|---|
| Breath (micrograms per 100ml) | 35 | 22 |
| Blood (mg per 100ml) | 80 | 50 |
| Urine (mg per 100ml) | 107 | 67 |
In January 2026 the government's Road Safety Strategy set out plans to bring England and Wales down to Scotland's limit, with a much lower limit of around 20mg for new drivers. That has not become law yet. If it does, new drivers in particular should stick to 0.0%.
The law that applies even under the limit
Section 4 of the Road Traffic Act 1988 makes it an offence to drive while unfit through drink or drugs, whatever your reading. That is why the honest rule is simple: if you feel anything other than normal, do not drive.
A few practical points:
- Check the ABV before you open it, not after.
- Driving straight after? Choose 0.0%.
- Drinking at the wheel is legal, but a can that looks like normal beer can get you pulled over. Save it for when you arrive.
- Going to Scotland, or a new driver? The margin is smaller, so pick 0.0%.
What about IMPOSSIBREW?
IMPOSSIBREW beers are 0.5% ABV, so a 440ml can holds 0.22 units. They are brewed with Social Blend™ (L-theanine, ashwagandha, magnesium and vitamin B1), which is designed to help you relax. They contain no caffeine.
Because the point of IMPOSSIBREW is to help you unwind, it is a drink for when the car keys are put away: at home, at the pub when someone else is driving, or after the journey. If you are about to drive, choose a 0.0% instead.
Frequently asked questions
Can you drink alcohol-free beer and drive in the UK?
Yes, it is legal. A 0.5% beer contains a small fraction of the alcohol in normal beer, and a 0.0% beer contains almost none. You can still be prosecuted if you are unfit to drive, so if you need certainty, choose 0.0%.
How many alcohol-free beers can you drink before driving?
There is no legal number, because the limit is measured in your breath or blood, not in drinks. A 440ml can at 0.5% holds 0.22 units, and the average adult clears about one unit an hour. If you want zero alcohol, choose 0.0%.
Can alcohol-free beer make you fail a breathalyser?
It is very unlikely, because the amounts are so small. A 0.0% beer contains almost no alcohol at all. Our separate guide covers whether alcohol-free beer shows up on a breathalyser.
Is 0.5% classed as alcohol-free in the UK?
Not under current UK guidance, which reserves "alcohol-free" for 0.05% and below. 0.5% drinks are described as de-alcoholised or low alcohol. The government is exploring raising the alcohol-free limit to 0.5%.
Is it illegal to drink non-alcoholic beer while driving?
No. But a can that looks like normal beer may get you stopped, and you can be prosecuted if you are unfit to drive for any reason.
Is the drink-drive limit changing in England?
The government plans to lower the England and Wales limit from 80mg to 50mg of alcohol per 100ml of blood, matching Scotland, with a lower limit for new drivers. Check GOV.UK for the date it takes effect.
