Proposed Drink-Drive Changes: Could One Drink Be Too Many?

Written by: Alan Baker 11th August, 2025

The UK government is reviewing drink-driving laws, with plans to cut the legal alcohol limit in England and Wales for the first time in over 50 years.


Why Is the Drink-Drive Limit Being Reviewed?

This reform is part of a wider road safety overhaul. Supporters of the change say it could:

– Reduce road deaths and serious injuries

– Align England and Wales with much of Europe’s drink-driving standards

– Send a strong public safety message that “just one more” drink could put drivers over the limit


How England and Wales Compare to Scotland

Scotland introduced a lower drink-drive limit on 5 December 2014, setting the legal threshold at 22 micrograms of alcohol per 100 ml of breath (50 milligrams (mg) per 100ml of blood). This is significantly stricter than the current limit in England and Wales, which stands at 35 micrograms per 100 ml of breath (80mg per 100ml of blood). The reduction in Scotland brought its drink-drive laws more in line with many European countries, where 50mg per 100ml of blood is the standard legal limit.

Studies indicate that the stricter threshold has helped raise public awareness about the risks of driving after even small amounts of alcohol.


Proposed New Drink-Drive Limits

If approved, the limits for England and Wales would change as follows:

Measurement Type         Current Limit     Proposed Limit
Blood Alcohol (BAC)         80mg/100 ml     50 mg/100 ml
Breath Alcohol         35µg/100 ml     22µg/100 ml
Urine Alcohol         107mg/100 ml     67mg/100 ml

 


What Happens Next?

– The proposals will go through government consultation in late 2025

– Legislation could be introduced in 2026

– If passed, this will be the first reduction in the drink-drive limit for England and Wales since 1967

The drink-drive reform is one part of a wider road safety package, which also includes:

– Eye tests for drivers over 70

– Possible technology-based enforcement measures

– Updated penalties for traffic offences


Key Takeaway for Drivers

If this change goes ahead, the safest and most responsible choice for drivers will be to avoid drinking alcohol entirely before getting behind the wheel. The proposed lower drink-drive limit means that even a small amount of alcohol such as “just one pint of beer” or “a single small glass of wine” could push a driver over the legal threshold. Alcohol concentrations can affect individuals differently depending on factors like body weight, gender, age and how quickly drinks are consumed, it can be difficult to accurately gauge how much is safe.
