AI Cameras Roll Out Nationwide to Target Illegal Driving Behavior

Police in the United Kingdom are beginning a large-scale rollout of artificial intelligence (AI)‑enabled cameras that automatically detect and capture drivers illegally using handheld mobile phones and those not wearing seatbelts. The system, which uses the Acusensus “Heads-Up” solution and is being provided in a partnership with infrastructure and engineering firm AECOM and National Highways, is already operational in at least ten police force areas and will run until March 2025, when a national rollout decision will be made.

The problem of mobile phone use while driving is considered one of the fatal four factors in serious road collisions in the UK, along with speeding, driving under the influence of alcohol or drugs, and not wearing a seatbelt. In fact, according to National Highways research, drivers using a handheld mobile phone are four times more likely to crash, while not wearing a seatbelt doubles a driver’s risk of dying in a collision. In 2023, over 1,600 people died in UK road collisions, many of them preventable with greater enforcement of mobile phone and seatbelt laws as reported by CyberNews.

Technology Origins and Deployment Timeline

The technology first went on trial in UK roads in 2021 in a “pop-up” configuration mounted on trailers. The first long-term deployment started in Devon & Cornwall police force area in August 2024, with a separate deployment and trial in Greater Manchester starting September 3, 2024. The units used in these programs use high-resolution and infrared cameras, either on trailers, vans, or gantries, to take still images of vehicles’ driver areas as they pass by. Exposure times are less than 50 microseconds, which eliminates motion blur at speeds of up to 70 miles per hour (112 kph), according to CyberNews.

Results From Trials Show Widespread Violations

Results so far are striking. In the pilot deployment in Devon & Cornwall in February–March 2024, the system recorded 408 seatbelt violations and 162 handheld mobile phone use violations in only two weeks, with a relocatable free-standing camera later recording 117 mobile-phone offences and 180 seatbelt violations in just 72 hours on the A30 at Launceston. Vehicle-based units observed 590 seatbelt offences and 45 phone offences over a 15-day trial period, as detailed in the Acusensus report.

A five-week trial in Greater Manchester identified over 3,200 people breaking the law, including 812 for mobile phone use and 2,393 for not wearing a seatbelt, according to Yahoo News. In Northamptonshire, the system collected data along the A5 for one week, which included 114 mobile-phone offences and 180 seatbelt violations. On the basis of these results, the UK government agreed to extend the system nationwide across ten forces until March 2025, with a national expansion to follow, subject to further review.

How the System Works: Human Review and Privacy Protection

Importantly, the system’s AI‑identified potential offences are not considered “automatically guilty.” Instead, those are subject to secondary human verification to confirm whether an offence occurred. Only in the case of a positive identification by trained verifiers does the system’s image collection lead to an enforcement action. Non-offending images are automatically deleted; only when a positive offence is confirmed are they retained, and all of the collected data is encrypted and handled according to GDPR standards.

Matt Staton, National Highways’ Head of Road User Safety Delivery, said: “Distracted driving, like using a mobile phone while at the wheel, and not wearing a seatbelt are two of the biggest causes of fatal crashes. By helping police to enforce the law, we believe technology like this will have a scalable deterrent effect and will make people seriously consider their behavior,” as covered by ITV News.

Penalties for Offenders

Penalties for offending drivers are nontrivial. Police may issue a fixed penalty notice of £200 and six points on the driving licence to those caught using a handheld phone. At court, fines can increase to up to £1,000, and for bus or HGV drivers the fines can be even greater, up to £2,500. Not wearing a seatbelt could lead to a fine of between £100 and £500, also on top of other charges according to GOV.UK.

Public Backlash and Privacy Concerns

However, not all of the reaction to the technology’s expansion has been positive. Some motorists and privacy groups have been vocal in their concern over the privacy implications of the AI system, in particular over the continuous monitoring of a car’s interior. In a survey, one in five drivers reported that they felt that the cameras were invading their privacy. Civil liberties groups including Liberty and Big Brother Watch have called on the government to impose a stronger legal framework and oversight for this type of AI‑enabled policing.

About Acusensus: The Company Behind the Cameras

The Acusensus company, based in Australia, was founded in 2018 in the wake of the death of a friend in a texting-related collision. It has since then grown into a global market leader in distracted‑driving enforcement, with headquarters in Perth and offices in New Jersey, Utah, Texas, Colorado, Australia, and the UK. To date, the company has over 100 deployments worldwide. In 2024, it also expanded its offerings to include not only static and mobile camera deployments, but also custom software to classify vehicles, identify driver posture, and recognise mobile phones with real-time processing and analytics as part of the Heads-Up system.

Next Steps: AI for DUI Detection and Predictive Enforcement

In future, the technology could be used to look for other types of offences. In December 2024, Devon & Cornwall police force launched a world-first AI‑enabled system to flag suspected drink or drug‑driving incidents by monitoring for erratic steering or lane departures. Data is automatically sent to a police call centre, where police located close to the incident can further investigate the situation in person, as reported by AutoExpress. The hope is that such solutions could help prevent collisions before they take place, ushering in a new era of road safety.

Conclusion: A Turning Point in Road Safety?

AI enforcement could eventually become permanent if results hold at scale. The next few months will determine whether this type of intervention is successful. The current trial is in place until March 2025. After that, it will be up to the government and its advisors to weigh in on its effectiveness, cost, impact on civil rights, and how the public feels about it, before a full nationwide expansion can take place, according to the BBC.

AI‑enabled traffic policing is entering a new era in the UK. Trials so far have identified tens of thousands of violations in a short period, prompting larger conversations around civil liberties and effective road safety enforcement. Praised by some as a life-saving technology and decried by others as Orwellian overreach, the AI camera program is already transforming road policing and driver behavior in the UK.
