The UK government has decided not to make breathalysers (alcolocks) mandatory in new cars, despite considering them as a potential tool to combat drink-driving.

Following a consultation that closed in May, officials confirmed that Alcohol Interlock Installation Facilitation (AIIF) will not be a legal requirement for new vehicles.AIIF is a system that allows breathalysers to be installed in cars driven by individuals with previous drink-driving convictions.

Instead, the government will mandate other safety technologies such as blind-spot warnings, tyre-pressure monitoring, drowsiness detection cameras, emergency braking systems, and Intelligent Speed Assistance (ISA) technology.These measures aim to reduce road accidents caused by human error.

While road safety organisations have expressed disappointment, the government argues that AIIF will remain under review as broader policies on alcohol interlocks develop.

Critics argue that the decision misses an opportunity to prevent repeat drink-driving offences, with studies showing strong public support for alcolocks in rehabilitation programmes.The RAC and other groups have called for the technology's inclusion, citing its potential to save lives.However, concerns about costs, implementation delays, and the prioritisation of other safety features have influenced the government's stance.
