London - New ‘noise cameras’ are to be used on Britain’s roads to catch 'boy racers' revving their engines.
The devices will detect excessively noisy vehicles in quiet residential areas and, like a speed camera, record the number plate.
Anyone caught breaking noise limits could be fined.
An initial trial has been commissioned by Transport Secretary Chris Grayling and will take place later this year.
The move is a response to growing concerns from police about noise pollution from car and motorbike engines.
