New research suggests public patience with the high drink drive limit in England and Wales is running out, with most people now backing tougher restrictions and stronger enforcement on the roads.

When the Government recently closed its public consultation on a new Road Safety Strategy, one issue stood out clearly: the drink drive limit.

Campaigners, clinicians and road safety experts have argued for years that the legal limit in England and Wales sits far too high. New findings suggest the public increasingly agrees.

Research commissioned by AlcoSense found that just 12% of people believe the current limit of 0.80 ‰BAC (80mg of alcohol per 100ml of blood) should stay the same. By contrast, 78% favour some form of reduction.

England and Wales now have the highest drink drive limit in Europe. Scotland reduced its own limit to 0.50 ‰BAC back in 2014, bringing it in line with most of the continent. Several countries have gone further still, adopting near zero limits for novice or professional drivers.

Despite this shift abroad, public debate in England and Wales still often treats the issue as though the evidence were uncertain. It is not.

Why the Drink Drive Limit Is Too High

One of the most persistent misconceptions in public debate is that risk only becomes serious as drivers approach 80mg. In reality, impairment begins well below the current drink drive limit.

Research published in the Journal of Studies on Alcohol and Drugs, based on more than 4,000 fatal crashes, found that the likelihood of a fatal collision rises sharply as blood alcohol concentration increases.

The figures are stark. At around 0.50 ‰BAC, the level currently used in Scotland, drivers were roughly five times more likely to be involved in a fatal crash than sober drivers. At 0.80 ‰BAC, that risk climbed to thirteen times more likely. The relationship is not gradual either. Risk accelerates quickly as alcohol levels rise.

This matters because 0.80 ‰BAC can still be presented publicly as a safe threshold. It is not. The legal limit marks the point where criminal liability begins, not the point where risk begins.

In practice, this means many drivers on English and Welsh roads remain legally entitled to get behind the wheel while measurably impaired. The gap between legal and safe is wide, and it is rarely understood by the public.

Even at one eighth of the current English limit, researchers identified a measurable rise in fatal crash risk. That finding sits alongside decades of evidence showing that alcohol affects reaction time, concentration, judgement and hazard perception long before drivers feel any different.

Public Support for a Lower Drink Drive Limit Grows

What stands out in the AlcoSense findings is not simply support for a lower limit, but backing for a wider package of road safety measures.

Three in four respondents supported roadside licence suspensions for drivers who fail or refuse a breath test. Nearly as many backed vehicle seizure powers for drink and drug driving offences, and seven in ten supported random breath testing.

The findings point to a public that increasingly sees drink driving as a public safety issue rather than a minor motoring offence.

Opposition to tighter drink driving laws has traditionally focused on inconvenience or concern for the hospitality trade. Those arguments now appear to carry less weight. More than a third of pub and restaurant visitors said their habits would not change if the limit was reduced, while only a small minority said they would visit licensed premises less often.

Evidence from Scotland points in a similar direction. Polling carried out in 2024, ten years after Scotland lowered its limit to 0.50 ‰BAC, found many motorists had changed their drinking habits entirely when planning to drive, with growing numbers choosing to avoid alcohol altogether before getting behind the wheel.

A majority of respondents said the most effective approach would combine a lower drink drive limit with stronger police enforcement, rather than relying on either measure alone.

Enforcement Matters As Much As the Law Itself

This may be the most important point to emerge from the debate. Changing the law alone is unlikely to shift behaviour if drivers believe enforcement is unlikely.

At present, England and Wales rely heavily on targeted campaigns and testing that takes place after incidents have already occurred. Random breath testing remains unavailable to police, and immediate roadside licence suspension is not currently permitted.

Many other countries take a different approach, where visible roadside testing forms part of routine traffic policing rather than occasional enforcement drives. That distinction matters, because the perceived likelihood of being caught is one of the strongest deterrents to drink driving.

The consultation also lands against a backdrop of continuing harm. Department for Transport figures show 260 deaths in drink driving collisions in 2023, alongside more than 6,000 injuries.

Drink driving deaths remain far lower than in the 1970s, yet progress has slowed. Fatalities fell to around 200 by the mid 2010s but have stayed stubbornly above that level despite major advances in vehicle safety technology. Each of those figures represents a death or injury that did not have to happen.

The Case for Reform Is Growing

Lowering the drink drive limit will not end drink driving on its own. No single measure ever could.

International evidence increasingly suggests that a lower limit, combined with visible enforcement and sustained public awareness, can help shift attitudes and reduce casualties over time.

This is not only a matter of punishment. It is a matter of clarity. The current 0.80 ‰BAC limit can unintentionally suggest that driving below that level is safe, when the evidence shows impairment and rising crash risk begin well before that point.

That is why road safety organisations and researchers continue to call for change, and why the safest choice for any driver remains the simplest one: leave the alcohol for another time.

The Government’s consultation has offered a chance to ask whether current drink driving laws still reflect the evidence, international practice and public expectation. Increasingly, all three appear to be pointing the same way.
