The DVS System Explained
The Direct Vision Standard (DVS) is a system designed to make the streets of London safer for pedestrians and cyclists. The DVS system applies to ALL 12 tonne and above vehicles that enter London. Without a permit, there’s a hefty £550 per day fine for non-compliance.
NOW AVAILABLE: The Progressive Safe System (PSS) is an enhanced version of the current DVS Safe System that fleet operators will need to install on their HGVs over 12T, so they can travel and operate legally within Greater London from October 2024.
From October 2024, the minimum DVS rating for HGVs entering and operating in Greater London moves from one star to three stars. Vehicles that have a two star rating or lower must have the PSS fitted and provide proof of this to obtain a permit.
All of the required DVS/PSS compliant audio-visual equipment can be ordered with us and installed by our mobile engineers.

Requirements
Improving indirect vision:
Camera Monitoring Systems (CMS) guidance will be updated to allow use of both systems. This will give the driver a wider field of vision and reduce the cognitive workload.
CMS fitted on vehicles must eliminate any remaining blind spots. This provides a visual alert of an approaching vulnerable road user and prevents collisions in the blind spot area.
Sensors must ensure full coverage down the nearside of rigid vehicles to detect vulnerable road users. They must not activate in relation to roadside furniture or stationary vehicles. This aims to prevent left turn collisions. For articulated trailers, sensors must be fitted to the front tractor unit but are recommended for the trailer where possible.
Moving Off Information Systems (MOIS) sensors must be fitted to the front of a vehicle to prevent collisions at the frontal blind spot zone when a vehicle moves off from rest.
Warning vulnerable road users of intended manoeuvres:
Audio warnings must be fitted to all vehicles, including those with left-hand drive to ensure all vehicles have the ability to warn of an intended manoeuvre.
Warning signage requirements remain unchanged.
Minimising physical impact of a hazard:
Sideguard requirements remain unchanged.
