New figures have reignited the national debate around repeat drink-driving; and could lead to major changes in how offenders are monitored on UK roads.
Data obtained by the RAC through a Freedom of Information request has revealed the true scale of alcohol-related motoring convictions across the country. More than 220,000 drivers currently hold drink-driving endorsements, with over 2,500 motorists caught three or more times in the last 11 years alone.
In response, road safety campaigners are pushing for the introduction of mandatory alcohol ignition interlock devices - commonly known as “alcolocks” - particularly for repeat and high-risk offenders.
What Is an Alcolock?
An alcolock is a breathalyser device connected directly to a vehicle’s ignition system. Before the engine will start, the driver must provide a breath sample. If alcohol is detected above a set limit, the car simply will not start.
In short - no clean breath test, no driving.
These systems are already used in several countries across Europe and parts of the US, particularly for drivers convicted of drink-driving offences.
The Scale of Repeat Drink-Driving in the UK
The RAC’s findings highlight a troubling pattern of reoffending:
-
Over 18,000 drivers have multiple drink-driving convictions
-
Some motorists have been convicted as many as six times
-
More than 2,500 drivers have three or more drink-driving endorsements
The two most common endorsements include:
DR10 – Driving or attempting to drive over the legal alcohol limit
DR20 – Driving while unfit through alcohol
Campaigners argue these figures prove that licence bans alone are not stopping persistent offenders from getting back behind the wheel.
Why the Government Is Considering Mandatory Alcolocks
Road safety groups are urging the Labour Party government to make alcolocks part of a court-ordered programme for repeat drink-drive offenders.
The logic is simple:
- Disqualification punishes
- Alcolocks physically prevent reoffending
RAC road safety spokesperson Rod Dennis summed it up clearly:
“Licence disqualification alone does little to stop some convicted drink-drivers reoffending. Alcolocks physically prevent a vehicle being driven after alcohol has been consumed.”
Public support is also strong, with 82% of drivers backing the introduction of alcolocks to reduce drink-driving.
Could Alcolocks Become Mandatory in All UK Cars?
At present, proposals are focused on repeat and high-risk offenders, not the general driving population.
However, as technology advances and pressure grows, some campaigners believe wider use across new vehicles could eventually follow; similar to seatbelelt laws, speed limiters, and safety assist systems.
For now, the most realistic next step is:
- Court-ordered alcolocks after drink-driving convictions
- Mandatory use during disqualification return periods
- Long-term monitoring of high-risk drivers
Will This Change Drink-Driving Prosecutions?
From a legal perspective, alcolocks could dramatically reduce reoffending rates; but they won’t replace existing offences.
Drivers could still face:
-
Drink-driving charges
-
Driving while unfit charges
-
Disqualification
-
Heavy fines
-
Prison sentences in serious cases
What alcolocks aim to do is stop repeat offences before they happen, rather than punish drivers after further harm occurs.
What This Means for Drivers Facing Drink-Driving Charges
While safety technology evolves, one thing remains constant: A drink-driving charge is still one of the most serious motoring offences in UK law.
Convictions can lead to:
-
Mandatory driving bans
-
Criminal records
-
Insurance premiums skyrocketing
-
Job loss in driving-related roles
-
In extreme cases, imprisonment
And, as MAJ Law regularly sees, not every drink-driving case is as straightforward as it first appears. Procedural errors, faulty evidence, unlawful stops, and testing issues can all affect whether a prosecution is legally sound.
Final Thoughts
The push for mandatory alcolocks highlights just how seriously repeat drink-driving is now being treated in the UK. With tens of thousands of reoffenders on the roads, and public support growing, significant legal reform may be closer than many drivers realise.
If you or someone you know is facing a drink-driving allegation, getting specialist legal advice early is essential.
At MAJ Law, we focus exclusively on motoring offences - challenging evidence properly, protecting licences wherever possible, and ensuring every case is tested fairly under the law.
