Direct Vision Standard

A HGV safety permit for operators entering London.

The Direct Vision Standard is an objective measure of the volume of space visible directly by the driver. HGVs will then be rated 0-5 stars where 0* is Poor direct vision and 5* is Excellent

Why is this being implemented?

The Mayor of London has adopted Vision Zero for road danger in our capital city, aiming for all deaths and serious injuries from road collisions to be eliminated from London’s streets by 2041. Vision Zero means ensuring the street environment incorporates safe speeds, safe behaviours, safe street design and safe vehicles to target road danger at its source.

How will this be achieved?

To achieve this target and reduce risk relating to heavy goods vehicles (HGVs) and people walking and cycling, TFL have developed the world’s first Direct Vision Standard (DVS) and will be issuing a safety permit for all lorries more than 12 tonnes GVW entering or operating in Greater London.

Safe HGV

How do I make my vehicle compliant?

If your vehicle does not meet the DVS star rating or is not rated, you will need to meet the ‘Safe System’ requirements to be granted a permit
