new technology will aim to detect illegal, excessively noisy vehicles.
New camera technology to be trialled by the government aims to measure the sound levels of passing vehicles to detect those that are breaking the law on noise limits, and could use automated number plate recognition to help enforce the law.
Research commissioned by the Department for Transport, found that a noise camera system could help tackle extremely noisy vehicles which breach legal noise limits.
All vehicles must legally meet strict noise limits before they are allowed on the road. Once a vehicle is in service, exhausts and silencers must by law be maintained in good working order and not altered to increase noise.
Studies have found that exposure to noise can have significant physical and mental health implications – with heart attacks, high blood pressure, type 2 diabetes and stress all linked to long-term contact with loud environments.
Currently, enforcement is mainly reactive and relies on subjective judgement. The trials of the new technology will determine whether the legal noise limit has been breached by taking into account the class and speed of the vehicle relative to the location of the noise camera.
