The UK Government has announced plans to reduce the legal drink-driving limit in England and Wales for the first time since 1967 — a move set to transform how motorists approach alcohol consumption before driving.

From autumn 2025, ministers are expected to introduce legislation lowering the legal blood alcohol concentration (BAC) limit from 80 milligrams per 100 millilitres of blood to 50 milligrams per 100 millilitres. This change would align England and Wales with the stricter limits already in place in Scotland and much of Europe.

Background: A First in Nearly Six Decades

The drink-driving limit in England and Wales has remained unchanged for almost 58 years. Introduced in 1967 under the Road Safety Act, the current threshold allows for 35 micrograms of alcohol per 100 millilitres of breath — equivalent to around 80mg BAC.

By comparison, Scotland reduced its limit to 50mg BAC in December 2014, and most European nations have long adopted the same or stricter rules. Campaigners have repeatedly argued that England and Wales are lagging behind in road safety standards, especially given advances in understanding the effects of alcohol on driving ability.

Government figures show that in 2023, 220 people died in collisions where a driver was over the legal limit, and thousands more were seriously injured. Safety advocates point out that even at the current legal level, reaction times are impaired and accident risk rises sharply.

The UK Government plans to cut the drink-driving limit in England and Wales from 80mg to 50mg of alcohol per 100ml of blood, matching Scotland’s stricter threshold. The change, expected after consultation in autumn 2025, means even one drink could put drivers over the legal limit. Officials say the move will improve road safety and reduce alcohol-related crashes.

Who Will Benefit from the New Law

This measure is expected to benefit a wide range of road users, from pedestrians to motorists, cyclists, and passengers. By lowering the limit, the likelihood of alcohol-related collisions should decrease, improving safety across the transport network.

Key beneficiaries include:

• Families and children — reducing the risk of serious accidents during school runs or family travel.

• Night-time commuters — especially those working late shifts, who often face greater risk from impaired drivers.

• Rural communities — where road lighting is limited, and drink-driving incidents are more frequent.

• Emergency services — potentially easing the strain on ambulance crews, police, and NHS accident and emergency departments.

Insurance experts also note that this change could lead to lower claims and premiums in the long term, provided the drop in collisions is significant.

Why the Change Was Made

The decision is rooted in a growing body of scientific evidence showing that impairment begins well below the existing 80mg BAC limit.

Studies conducted by the UK’s Department for Transport and the World Health Organization suggest that drivers with a BAC between 50mg and 80mg are six times more likely to be involved in a fatal crash compared to sober drivers.

Public pressure has also played a role. Over the past five years, road safety charities such as Brake and the Royal Society for the Prevention of Accidents (RoSPA) have campaigned vigorously for reform. A YouGov poll in 2024 found that 71% of the public supported lowering the limit, with strong backing from younger drivers and parents.

Medical organisations, including the British Medical Association (BMA), have warned that the current threshold creates a false sense of security, encouraging some motorists to “push their luck” and misjudge their level of intoxication.

How the New Limit Will Work

Under the proposed legislation, the drink-driving limit in England and Wales would change as follows:

*Note: Alcohol affects individuals differently depending on weight, gender, metabolism, and food intake.

Enforcement would still rely on roadside breathalyser tests, with suspected offenders taken to police stations for further confirmation. However, police forces are expected to increase random testing, especially in nightlife areas and during holiday seasons.

The government will launch a public awareness campaign ahead of implementation, warning drivers that even one drink could put them over the new limit. Campaign slogans may mirror Scotland’s 2014 approach — “None for the Road.”

Impact on the Public

The change is expected to alter social habits around alcohol and driving. Pubs, restaurants, and event organisers may see more customers opting for alcohol-free alternatives or arranging designated drivers.

For motorists, the safest choice will be total abstinence from alcohol before getting behind the wheel. With the reduced limit, it’s possible for a person to fail a breathalyser after just half a pint of beer or a single small glass of wine.

Businesses could also be affected. Employers with fleet vehicles or staff who drive for work will need to update internal policies, provide awareness training, and potentially offer alternative travel arrangements.

The NHS anticipates fewer alcohol-related road trauma cases, which could save millions in public healthcare costs annually. Meanwhile, road safety advocates hope the new law will also deter “morning after” driving when alcohol remains in the bloodstream from the previous night.
