The Direct Vision Standard (DVS), introduced in March 2021, set a new benchmark for road safety in the Greater London area, requiring heavy vehicles over 12 tonnes to obtain a safety permit.
From 28th October 2024, the minimum star rating for vehicles will increase from 1-star to 3-star. Vehicles that don’t meet this new rating must either be replaced or retrofitted with Progressive Safe System (PSS) measures.
Non-compliance with these updated standards could result in a £550 fine per violation, making it crucial for fleet operators to understand the new requirements and implement the necessary changes. In this guide, we will explore the Progressive Safe System (PSS), its purpose, and how to ensure your vehicle meets the new DVS requirements.
What is the Progressive Safe System (PSS)?
The Progressive Safe System (PSS), set to replace the existing Safe System in October 2024, is designed to enhance road safety by reducing the risks that heavy goods vehicles (HGVs) pose to vulnerable road users, such as cyclists and pedestrians.
Vehicles with a star rating below 3 must be upgraded or retrofitted with the PSS safety measures to meet the new DVS standards.
The PSS focuses on three core safety objectives:
- Improving indirect vision.
- Warning other road users of intended manoeuvres.
- Minimising the physical impact of a hazard. Below, we break down each of these goals and explain the measures required to achieve compliance.
1. Improve Indirect Vision
A star rating of 2 or lower indicates a higher risk of close proximity collisions, so enhancing indirect vision is vital.
To comply with the PSS, vehicles must be fitted with the following safety features: Camera Monitoring Systems: A fully operational camera system must cover all vehicle blind spots.
The feed should be easily viewable by the driver, minimising the time spent shifting their gaze.
Class V and VI Mirrors
These mirrors improve the driver’s view of the nearside and front of the vehicle. For left-hand drive vehicles, ensure the mirrors adequately cover blind spots on the right-hand side.
Sensor Systems with Alerts
Sensor systems should be installed to alert drivers to pedestrians or cyclists in proximity. The sensor should cover a 6-metre range along the side or 1 metre behind the vehicle and must be programmed to avoid false alerts, such as from stationary objects like streetlights.
It’s essential to perform regular checks to ensure that these systems are functioning correctly. Any malfunctioning equipment should be repaired or replaced immediately.
2. Warn Road Users of Intended Manoeuvres
Beyond improving visibility, vehicles must also be equipped with systems that effectively warn other road users of upcoming manoeuvres.
Audible Vehicle Manoeuvring Warning
An audible alert system should be installed to inform pedestrians and cyclists when the vehicle is turning. The warning must be between 65 and 88 decibels, using a combination of white noise and verbal messages for maximum clarity.
Warning Signage
Clear visual warnings must be displayed on the vehicle exterior, alerting other road users to potential hazards. These stickers should include simple messages like “Blind Spot: Take Care” and must be regularly checked to ensure they remain visible and legible. Both audible and visual warnings should be inspected frequently to guarantee they are in proper working order.
3. Minimise the Physical Impact of a Hazard
To reduce the severity of collisions, vehicles must be equipped with side protection to prevent vulnerable road users from being caught underneath.
Side Under-run Protection
Sideguards should be fitted on both sides of the vehicle, except where impractical (e.g., for road sweepers or gully emptiers). The sideguards should work in conjunction with the vehicle’s visual warnings to further reduce risk.
Ensuring Compliance with the Direct Vision Standard (DVS)
By 28th October 2024, vehicles operating in Greater London must have a minimum DVS rating of 3 stars.
For vehicles with lower ratings, the Progressive Safe System (PSS) measures outlined above must be implemented to achieve compliance. Fleet operators have the choice to either retrofit their existing vehicles or invest in new, compliant models.
