Vehicle exhausts and antisocial behaviour

Alert message sent 12/11/2020 21:03:00

Exhaust Noise – The Law

Motor vehicle exhausts, which have been modified to increase noise, can cause annoyance and distress to members of the public and therefore can be regarded as instruments of antisocial behaviour.  Many people are affected, who are then prompted to call to the police.  Nobody is impressed!
     There has long been controversy among motorists - fuelled by so much internet misinformation - as to the legality, or otherwise, of modified exhaust systems, so I would like to clarify the matter regarding drivers’ responsibilities and the law, and dispel the myths.
Regulation 54 (2) of the Road Vehicles (Construction and Use) Regulations 1986 states that: “Every exhaust system and silencer shall be maintained in good and efficient working order and shall not, after the date of manufacture, be altered so as to increase the noise made by the escape of exhaust gases”.
Therefore, any motorist who is driving a vehicle which has been fitted with an exhaust system, which does not conform to the Type Approval for their particular vehicle and which results in more noise, is committing an offence.
Anyone found by the police to be driving a vehicle in this condition is liable to be reported for summons.
     It is not an excuse that the exhaust was modified by the previous owner; the driver is responsible.
Sound measuring equipment is not required to establish the noise level; a police officer’s professional judgement is sufficient.
An MOT pass is not proof that an exhaust system is legal.
Notifying your insurance company does not make the modification legal.
       The Derbyshire Police would like to remind any motorist who is intending to modify their vehicle that their licence to drive is a privilege and not a right, and they must give consideration both to residents and road users alike.  We are committed to suppressing all antisocial behaviour, including that which is waged upon the highways.

Please report vehicle antisocial behaviour.
