To ask the Secretary of State for Transport, pursuant to the Answer of 5 February 2018 to Question 256295, Motor Vehicles: Carbon Emissions, what steps a member of the public can take if they want to report a private vehicle that has an excessively smoky exhaust and may not be meeting the required emissions standards.
The Road Vehicles (Construction and Use) Regulations 1986, as amended, requires all vehicles to meet strict emission standards and be constructed and maintained so as not to emit any avoidable smoke or avoidable visible vapour.
The police are responsible for enforcing these requirements on public roads for light goods vehicles and private cars. They also have powers, under Regulations 54 and 61 of the Regulations, to take action if they suspect a vehicle is in breach of these regulations.
The Government would encourage members of the public to bring such problems to the attention of the police through their neighbourhood policing teams to ensure they are given an appropriate priority.
Additionally, the Driver and Vehicle Standards Agency operate a website so that members of the public can report heavy goods vehicles that appear to have excessively smoky exhausts.
