Wales Cracks Down on Engine Idling with Fines Rising to £150

Drivers across Wales who leave their engines running while parked will from Wednesday be liable for fines of up to £150, following a significant increase in the penalty for so-called idling. The change, introduced by the Welsh government, raises the previous fixed penalty of £20 to a range of between £75 and £150, with the exact amount depending on the circumstances of the offence. The new measure is aimed at cutting harmful pollution and protecting public health, particularly around schools and healthcare facilities.

The previous £20 charge had remained unchanged since it was first introduced in 2003, meaning it had stayed at the same level for more than two decades. Ministers argued that this figure was no longer sufficient to discourage drivers from leaving their engines running unnecessarily, and that a higher penalty would act as a more effective deterrent.

Llyr Gruffydd, the cabinet minister for rural resilience and sustainability, said the old £20 fixed fine was "insufficient" and was not being used "in the way everyone might envision it". He said increasing the amount available to local authorities to penalise drivers would provide a "stronger deterrent". Gruffydd added that the government felt it needed to "step up here, clamp down on this as a problem and make sure we protect people's health", describing the change as something that would generally make communities better places to live.

He also expressed hope that the higher range of fines would "change the habits of people who are polluting communities and are putting children and vulnerable people's health at risk". The Welsh government has framed the policy as part of a broader effort to reduce air pollution in built-up areas, where vehicles are often left running while stationary.

The rules around idling are already set out in the Highway Code. Under rule 123, drivers must not leave a parked vehicle unattended with the engine running, nor leave an engine running unnecessarily while the vehicle is stationary on a public road. The new penalty regime gives local authorities a stronger financial tool to enforce that guidance, although questions remain about how widely it will be applied in practice.

Areas outside schools have been identified as high-risk sites where emissions pose particular concerns, partly because children gather in large numbers and their developing lungs are more susceptible to pollution. Hospitals, GP surgeries, care homes and other healthcare facilities have also been classified as high-risk locations, given the presence of older people and those with existing medical conditions.

Professor Isabel Oliver, chief medical officer for Wales, said air pollution was a serious public health issue that contributed to a range of conditions including heart and lung disease. She noted that children, older people and those with existing health conditions are particularly vulnerable to its effects, and argued that while idling may seem like a small, everyday habit, it adds up over time. According to Oliver, every time an engine is switched off rather than left running, the amount of harmful pollution in the air people breathe is reduced, especially around schools, hospitals and other places where vulnerable people spend time.

The measure came into force following a vote at the Senedd in March. Members of the Senedd passed the new rules with 37 politicians voting in favour and 12 against, with no abstentions recorded. The vote followed debate about how best to balance public health concerns with the practicalities of enforcement and the daily routines of drivers.

At Treganna school in Cardiff, parents offered mixed views on the change. Anna, who was collecting her children, welcomed the new measure, describing the area around the school as "really, really busy because cars are everywhere around here". She said that during certain hours it could be difficult to leave, and recalled one occasion when it took her 45 minutes to get down the road. For her, the policy is a positive step because it may stop some cars from parking near the school.

Another parent, Chiara Rinaldi, said she believed there was a good principle behind the fines but doubted whether they would be enforced. She described school runs as chaotic and questioned whether police would ever be present to issue penalties, suggesting the idea was sound but unlikely to be put into practice on the ground.

Wendy Vernon-Fulook, a parent who frequently walks to collect her children, took a more supportive view. She said the higher fine was a "good thing", arguing that leaving a car running is obviously not good for the environment and might discourage some people from doing it. She acknowledged that some drivers may continue regardless, but said efforts to encourage walking made the change worthwhile.

Not all parents were convinced, however. Rhiannon Simmonds said she was not sure she agreed with a "mandatory solution" to the problem, though she said she completely appreciated the logic behind what the government is trying to achieve. Her comments reflect a broader tension between the public health rationale for the fines and concerns about how they will be applied fairly and consistently.

The Welsh government's decision is likely to be watched closely by local authorities, environmental groups and motoring organisations. Supporters argue that higher fines could reduce unnecessary emissions in congested areas and improve air quality where it matters most. Critics, meanwhile, may question whether councils have the resources to monitor idling and whether the penalty will fall disproportionately on certain drivers. For now, the message from ministers is clear: leaving an engine running unnecessarily in Wales now carries a much higher financial cost.
