Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 27 October 2020 to Question 105392 on Motorcycles: Noise, whether his Department plans to publish its research into whether noise enforcement can be made more effective using acoustic camera technology; and if he will make a statement.

The results of the Department’s initial research into the use of a prototype noise camera for the detection of excessively noisy vehicles was published in August 2021. This research showed that the technology demonstrated some potential but required further development to be suitable for enforcement.

Further trials were commissioned in 2022, which included the assessment of the latest noise camera technology on a test track and at the roadside. Roadside trials were undertaken at four sites between October 2022 and February 2023. The Department is currently reviewing the outcomes of the trial before considering any next steps and will publish the final research report in due course.
