Wales to raise idling fines to £150 to curb pollution

From 30 September drivers who leave their engines running while parked can be hit with fines of up to £150 across Wales.

The Welsh Government has lifted the fixed penalty for stationary idling from the current £20 to a band of £75‑£150, a move aimed at curbing air and noise pollution in towns and cities.

Under Rule 123 of the Highway Code, motorists must not leave a vehicle unattended with the engine running, nor keep it running unnecessarily while stationary on a public road.

Local authorities will be empowered to enforce the new charge, deciding where and when to target the offence in their respective areas.

Health officials warn that idling engines emit fumes that contribute to heart and lung disease, with children, older people and those already ill being the most at risk.

“Idling engines pump out fumes that people breathe in, including children outside schools and vulnerable people outside healthcare settings,” said Cabinet Minister for Rural Resilience and Sustainability Llyr Gruffydd during a visit to Marshfield Primary School in Newport.

The minister joined pupils who have been part of a Welsh Government‑funded anti‑idling project run with Newport Council, where they designed a banner urging drivers to switch off their engines.

The banner now hangs outside the school, a visible reminder that a simple habit can have a measurable impact on local air quality.

Chief Medical Officer for Wales Professor Isabel Oliver stressed the broader public‑health implications, noting, “Air pollution is a serious public health issue, contributing to a range of conditions including heart and lung disease.”

She added, “Idling may seem like a small, everyday habit, but it adds up.” Every time an engine is switched off rather than left running, we reduce the amount of harmful pollution in the air we all breathe, particularly around schools, hospitals and other places where vulnerable people spend time.”

Professor Oliver urged motorists to treat switching off an engine as a normal part of parking, not only to avoid fines but to protect community health.

The new penalty regime follows a series of Welsh Government initiatives to improve air quality, including low‑emission zones and stricter vehicle inspection standards.

Transport analysts predict that the higher fines will encourage a cultural shift, especially among drivers who habitually idle while waiting for passengers or while loading goods.

Local councils are already planning awareness campaigns, with some considering additional signage near schools, hospitals and busy junctions to remind drivers of the rule.

Environmental groups have welcomed the step, arguing that reducing idling can cut carbon dioxide emissions by an estimated 0.5 tonnes per 1,000 vehicles each year.

Business owners, however, have raised concerns that the penalty could affect delivery drivers and small‑scale traders who rely on short stops to keep engines warm in colder months.

The Welsh Government has indicated that enforcement will focus on high‑traffic areas and locations where vulnerable populations gather, rather than targeting occasional, low‑risk incidents.

Police forces across the nation have been briefed on the new powers and will be equipped with training to identify and record offences efficiently.

Legal experts note that the fixed‑penalty system allows for swift processing, reducing the burden on courts while still delivering a deterrent effect.

As the September deadline approaches, motorists are being urged to check their vehicle settings and adopt the habit of turning off the engine whenever the car is stationary for more than a minute.

Failure to comply could see drivers facing a £75 fine for a first offence, rising to £150 for repeat breaches, according to the new schedule.

With the health stakes high and public awareness growing, the Welsh Government hopes the measure will contribute to cleaner air and healthier communities across the nation.
