Direct Vision Standard Equipment & FORS solutions

As part of the Mayor of London’s #VisionZero plan to eliminate all deaths and serious injuries on London’s Transport Network by 2041, the Direct Vision Standard (DVS) was designed to minimise the risk to Vulnerable Road Users (VRU) caused by poor driver vision.

Under the current scheme, HGV’s over 12 tonne with a zero-star DVS rating must be fitted with a ‘Safe System’ to operate in London.

DVS star ratings are based on how much the driver can see directly through the vehicle’s cab windows of the area around the vehicle, where collisions are most likely to take place.

TfL have now introduced the ‘Progressive Safe System’ (PSS). From 28th October 2024 requirements will be enhanced and the minimum DVS rating required will be three-star rating. This means that vehicles rated two-star or below on the DVS rating scale will need to fit the new PSS to operate in Greater London.

What is the Progressive Safe System (PSS)

The PSS is a set of vehicle safety measures, fitted after or at the point of manufacture, which are designed to reduce the risks that HGVs present to VRUs.

• Camera Monitoring Systems (CMS): To provide a visual alert of an approaching VRU & prevent collisions in the blind spot areas.
• Moving Off Information System (MOIS): Involves installing a front-mounted vehicle systems to alert drivers about nearby VRU within a two-meter radius. The system must avoid false alerts and provide additional signals for imminent collisions.
• Sensors: Must ensure FULL coverage down the nearside of rigid vehicles to detect VRU. They must not activate to roadside furniture or stationary vehicles
• Audio Warnings: Must be fitted to provide an adequate audible warning to VRU when a vehicle is turning left.
• Warning Signage: Illuminated or non-illuminated be displayed on vehicles to provide adequate visual warning to VRU.
