Transport noise

Learn about the impact of transport noise, how we regulate it and what you can do to manage it.

Transport noise is a part of everyday life, particularly in urban areas. Common sources of transport noise are:

  • cars and motorcycles
  • vans, trucks and buses
  • road traffic
  • passenger trains and trams
  • freight trains.

For vehicles on residential property, visit Residential noise. For vehicles at a construction site, visit Construction noise.

Transport noise and the law

The general environmental duty applies to managing transport noise. This is important for people who design roads. The unreasonable noise duty also applies to transport noise.

Motor vehicles

Under the Environment Protection Regulations 2021(opens in a new window), motor vehicles must meet noise standards when travelling on roads.

It’s against the law to:

  • use, or permit the use of, a vehicle that breaks noise standards
  • sell a motor vehicle that breaks noise standards
  • modify a vehicle so that it doesn’t meet noise standards.

Motor vehicles include:

  • cars
  • motorcycles
  • light trucks up to 4.5 tonnes
  • buses up to 4.5 tonnes.

Vehicle noise is also covered under regulation 289 of the Road Safety (Vehicles) Regulations 2021(opens in a new window).

Trains and trams

Trains and trams are exempt from the noise requirements in the Environment Protection Act 2017 when:

  • carrying passengers
  • preparing for a passenger service.

However, you can still report noise from public transport.

Noise from trains and trams that are not in service can be unreasonable. This means when they are being moved, maintained and cleaned in a siding, marshalling yard or maintenance depot. These activities must comply with noise requirements for commercial, industrial and trade premises.

Reduce transport noise

You can help to reduce transport noise and its impacts by:

  • walking or cycling instead of driving

The design, construction and maintenance of roads and rail infrastructure can help manage the impact of transport noise. Find out about:

New homes and apartments near busy roads, railways and industry should include noise protection for residents. Learn about:
