Six-in-10 drivers (58%) questioned by the RAC said they would be in favour of so-called ‘noise cameras’ being widely used once the findings of the Department for Transport’s £300,000 trials, which began last October, are revealed. Only a fifth (22%) were against the idea, with a similar proportion (20%) unsure.
The cameras, which are triggered by a number of microphones, can pinpoint vehicles exceeding the 74-decibel legal limit as they pass by. Pictures of vehicle numberplates together with recordings of the vehicle noise are then used by local police to identify and fine drivers. Trials took place in Bradford, Great Yarmouth, Birmingham and South Gloucestershire near Bristol.
A third (34%) of those who took part in the RAC study said they regularly hear loud revving engines or excessively loud exhausts. This rose to nearly half of drivers in London (47%) and to 40% in Wales and Scotland. Half of all drivers (51%) questioned said they occasionally hear one or more vehicles with particularly loud exhausts.
- Noise camera trials to take place across England to tackle ‘boy racers’
- New AI speed camera with 4D radar technology can scan drivers inside a vehicle
- Drivers warned about new stealth speed camera vans
- Exhaust repair
Asked for their opinions about whether the current £50 on-the-spot fine for a vehicle breaching the 74-decibel limit is appropriate, drivers were split.
Four-in-10 (39%) felt the fine had been set at the right level whereas 37% disagreed, and a quarter (24%) were undecided. Of those who felt the fine wasn’t severe enough, 43% thought it should carry a £200 fine and a driving ban until the exhaust was found to comply with the legal decibel limit. Among Londoners this shot up to more than two-thirds (67%).
Road noise is known to contribute to health problems, such as heart attacks, strokes and dementia, yet there is no requirement for MOT testers to use decibel meters to check exhaust noise levels.
The Government estimates the annual social cost of urban road noise, including lost productivity from sleep disturbance and health costs, is up to £10bn**.
RAC head of policy Simon Williams said: “Our research with drivers shows there is a very strong desire to put an end to the scourge of excessively noisy vehicles that disturb the peace all around the country.
“It’s plain wrong that those who have fitted their cars with modified exhausts, some motorbike riders and supercar owners can currently just get away with making an unacceptable amount of noise. Fortunately, the Department for Transport’s recent noise camera trials may provide the solution. We hope the findings are positive and that the technology can be quickly and cost-efficiently rolled out to the worst affected areas.
“There is no good reason why cars and motorbikes should make so much noise, so the sooner effective camera enforcement can be put in place the better.”
Roads Minister Richard Holden said: “Boy racers are an anti-social menace and we have extensively trialled noise camera technology in various parts of the country over the past year.
“We are currently analysing data from the trials and will update in due course on any future measures which will help bring peace and tranquillity back to our towns, cities and villages.”
The London Borough of Kensington and Chelsea was the first local authority to trial acoustic cameras in May 2022.***
