Road Traffic: Noise

The Government takes the impact of excessive noise on health, wellbeing and the natural environment seriously. Strict noise regulations for cars and motorcycles are harmonised at an international level and require vehicles to demonstrate compliance before being placed on the market. Replacement silencers that are to be used on the road must also meet strict noise limits that are aligned with those of the original vehicle.

The Department for Transport conducted roadside trials of noise camera technology between October 2022 and February 2023. Reports of these trials, including detailed assessment of the technology’s performance and potential merits, were published on 17 March 2024. Overall, the trials demonstrated that noise cameras currently have the potential to be used for enforcement, but only when accompanied by human review of the recorded evidence, which is likely to lower the cost effectiveness of deploying the technology in many circumstances.

It is ultimately for local authorities and the police to consider what the most appropriate enforcement routes may be for addressing issues with excessive vehicle noise within their area. The use of noise camera technology has already been taken forward by some local authorities.
