Alcohol and transport

• Drink driving
• Alcohol in airports

One of the most significant changes in British drinking culture over the last 40 years has been the decline in drink driving. Driving under the influence was not a social taboo before the invention of the breathalyser, the introduction of new laws on blood alcohol limits, and the use of hard-hitting information campaigns.

Today, while drink driving remains the cause of far too many injuries and deaths, our social norms have mostly changed. There is greater awareness that alcohol increases our risk of injuries and fatalities by impairing our ability to drive.

However, drink driving still causes many preventable injuries and fatalities. We have seen that these can be reduced, but to cut them further we need to address the anomaly in our system and bring our law into alignment with the rest of the world.

What is the drink drive limit in the UK?

The legal drink driving limit differs across the United Kingdom. There are also different ways of understanding how much alcohol is in our system, as set out by the relevant legislation:

England and Wales have one of the highest legal limits in the world, as most countries have limits between zero and 50mg alcohol/100ml blood.¹ Seven countries in the European Union have limits between zero and 20mg alcohol/100ml blood.² The legal drink driving limit in England and Wales has not changed since 1967.

What does the evidence show?

There is clear evidence that lowering the legal limit will reduce road collisions and save lives:

Evidence from Scotland, which has had a lower BAC limit of 50mg alcohol/100ml blood since 5 December 2014, suggests that lowering the limit should be accompanied by access to cheaper, alternative transport and adequate law enforcement.^{7 8}

What does the public think?

Public polling has consistently shown support for lowering the legal drink driving limit.

According to a 2025 survey of 2,000 UK adults:⁹

• 87% believe stricter laws are needed to stop people getting behind the wheel under the influence
• 78% want the existing drink-drive limit of 80mg alcohol/100ml blood slashed
• 28% said it should be brought in line with Scotland’s 50mg alcohol/100ml blood
• 50% said it should be cut to 20mg alcohol/100ml blood

What does Alcohol Change UK think?

We agree with the public that it if we choose to drink alcohol, we should not be driving.

We support reducing the limit to 20mg alcohol/100ml blood.

This is essentially a “zero-tolerance” limit, which allows for low but traceable levels of alcohol which may exist in someone’s body, and for minimal presence of alcohol, like if someone has used mouthwash or certain medications.

Currently, the existing 80mg alcohol/100ml blood limit makes some people think that they can drive after having one or two drinks, trying to figure out how long it will take for the alcohol to leave their system depending on how much they’ve eaten, their body weight, and other factors. A 20mg alcohol/100ml blood limit sends a much clearer message – “don’t drink and drive” – and we know that clear messaging results in better outcomes.

The UK Government is consulting on lowering the limit. Find out more and respond to the consultation before 11 May 2026.

In the UK, any premises selling alcohol needs to be licensed. This has been the case for centuries and allows for basic controls on the way alcohol is sold and maintained. The one exception to this is airports, where – once airside – licensing laws no longer apply.

This is a clear anomaly that needs to be addressed. This is not to say that alcohol should be banned from airports – though, given the rising levels of alcohol-related disorder passengers suffer on flights, there are growing calls for some kind of restriction to be introduced. It is, rather, to ask that airport operators follow the same rules as every other alcohol retailer in the country. Anyone selling alcohol should be licensed to do so, and the conditions of that licence should be adhered to. There is no reason why that should apply less in an airport than anywhere else.
