The end of October marks a year until the new Direct Vision Standard (DVS) are introduced.

From 26 October 2020 we will introduce DVS standards for HGVs as well as buses, coaches and other specialist vehicles, driving within Greater London. These will operate 24 hours a day, every day of the year. This action is crucial because every Londoner has the right to safer roads. The is the same date that we are tightening the Low Emission Zone standards, to encourage the most polluting heavy diesel vehicles driving in London to become cleaner.

Reducing the risk posed by dangerous vehicles is at the heart of Vision Zero for London, through which we will eradicate deaths and serious injuries from our roads and make London a safer, healthier and greener place.

Low Emission Zone

Emission standards are tightening from Euro IV Particulate Matter only (PM) to Euro VI Nitrogen Oxides (NOx) and PM. The LEZ emission standards will be changing for the following heavy vehicles with diesel engines:

  • Buses, coaches and minibuses over 5 tonnes
  • HGVs, lorries, vans and other specialist heavy vehicles over 3.5 tonnes including motor caravans, motorised horseboxes, breakdown and recovery vehicles, snow ploughs, gritters, refuse collection vehicles, road sweepers, concrete mixers, fire engines, tippers and removal lorries

Direct Vision Standard

The world leading new DVS is part of the Mayor of London’s plans to eliminate death and serious injury on London’s transport network. Using a star system, the DVS will rate HGVs from zero (lowest) to five (highest) stars, based on how much a driver can see directly through their HGV cab windows. Restrictions in the HGV driver’s field of vision, or ‘blind spots’ have been identified as a significant contributory factor in collisions with vulnerable road users, such as people walking and cycling.

From 26 October 2020 HGVs weighing more than 12 tonnes will be required to hold a HGV Safety Permit when operating within Greater London (the same area as the Low Emission Zone). There will be no charge for permits. Permits will be available a year in advance, from today, and can be applied for at
