A recent survey has revealed that four in five UK motorists support fitting cars with breathalysers to tackle drink-driving, highlighting strong public demand for tougher road safety measures. These devices, also known as alcolocks, require drivers to provide a breath sample before starting their vehicle, preventing the engine from running if alcohol is detected. With drink-driving still responsible for thousands of accidents each year, many believe mandatory breathalysers could dramatically reduce reoffending rates.
The findings suggest motorists are ready for stricter enforcement, and the government may face increasing pressure to adopt this technology as part of its road safety strategy.
Public Support for In-Car Breathalysers
According to a poll commissioned by the RAC, 82% of UK licence holders support the installation of in-car breathalysers — also known as alcohol interlock devices or “alcolocks” — to reduce drink-driving offences. These devices require drivers to provide a breath sample before starting their vehicle, preventing the engine from running if alcohol is detected.
The survey highlights growing frustration among motorists who believe existing penalties are not enough to deter repeat offenders. Since 2010, 17% of drink-driving offences have been committed by individuals with a prior conviction, underscoring the need for stronger interventions.
How Breathalysers Work
Breathalysers in cars are not new. Countries such as Belgium, the Netherlands, Australia, Canada, and the US already use alcolocks for convicted drink-drivers, often in exchange for shorter bans. The technology is simple but effective: if the driver fails the breath test, the car won’t start.
Supporters argue that this real-time safeguard could save lives by stopping intoxicated drivers before they even hit the road. Critics, however, raise concerns about cost, practicality, and whether mandatory breathalysers for all drivers would be too intrusive.
Linking to Wider Policy Debates
The call for in-car breathalysers comes at a time when UK motorists are already facing new policies such as the pay-per-mile tax on electric cars. Just as drivers worry about being penalised financially for greener choices, many now want reassurance that road safety is being prioritised.
The overlap is clear: whether it’s taxation or technology, motorists are increasingly aware of how government decisions affect their daily driving experience. Breathalysers represent a measure that, unlike new taxes, could directly improve safety and reduce fatalities.
The Case for Mandatory Installation
The RAC survey found that 71% of drivers believe every motorist caught over the legal limit should be forced to have a breathalyser fitted. A further 23% think the devices should be reserved for repeat offenders. This shows strong public appetite for targeted enforcement rather than blanket rules.
Campaigners argue that mandatory breathalysers for convicted drink-drivers could cut reoffending rates dramatically. With drink-driving still responsible for thousands of accidents annually, the potential impact is significant.
International Lessons
Looking abroad, the evidence is compelling. In Australia and the US, alcolocks have been credited with reducing drink-driving reoffences by up to 64%. In the Netherlands, they are part of rehabilitation programmes that combine technology with education.
If the UK were to adopt similar measures, it could align with global best practice while addressing a persistent road safety issue.
Final Thoughts
The debate over breathalysers in cars reflects a wider shift in motoring policy. While taxes like the pay-per-mile scheme risk dampening enthusiasm for electric cars, measures such as alcolocks could win public support by tackling dangerous behaviour head-on.
With four in five motorists backing the idea, the government faces a clear mandate: prioritise safety, reduce reoffending, and ensure that Britain’s roads are protected from the devastating consequences of drink-driving.
With 4 out of 5 motorists backing the idea of fitting cars with breathalysers, some drivers may be rethinking their next vehicle choice.
