Traffic Emissions

Report a polluting engine

Poorly maintained engines produce more pollution than those that are well maintained. You can report an excessively smoky lorry or bus to the Driver and Vehicle Standards Agency (DVSA).

The information required to trace the vehicle operator is:

  • type of vehicle (e.g. HGV or a Passenger Service Vehicle)
  • the vehicle’s registration number
  • company name (if apparent)
  • road name/number where vehicle seen
  • when you saw the vehicle (date and time)
  • your name and address (not compulsory and is confidential)

Idling Vehicles

Idling of a vehicle is when the engine is running while the vehicle is not in motion. It is an offence for a vehicle to idle its engine unnecessarily.

Idling vehicles create emissions containing a range of pollutants such as carbon monoxide, nitrogen dioxide and particulate matter. These emissions can affect the air quality of the surrounding environment and the air we breathe.

The Road Traffic (Vehicle Emissions) (Fixed Penalty) (England) Regulations 2002 allow Local Authorities in England to issue a £20 fixed penalty notice to drivers who allow their vehicles to idle whilst on the road, if the engine is not switched off after being instructed by an authorised officer.

There are however, some situations where the vehicle will be allowed to run while stationary and a fixed penalty notice will not be issued.  These include:

  • While in a traffic jam or stationary at traffic lights.
  • While defrosting or running air conditioning as weather conditions dictate.
  • Where a vehicle is broken down and the engine is running for diagnostic reasons.
  • To facilitate the operation of on board equipment i.e. refrigeration.

Monday to Thursday: 9am to 5pm
