As part of the Mayor of London’s Vision Zero plan to eliminate all deaths and serious injuries on London’s transport network by 2041, TFL are now proposing an enhancement to the current Direct Vision Standard (DVS) ‘Safe System’ with the introduction of the ‘ProgressiveSafe System’ (PSS) from October 2024.

Under the current scheme, HGVs over 12T must meet a minimum standard, where vehicles do not meet a minimum of one-star rating operators are required to implement a series of vehicle safety measures, which are designed to reduce the risks that HGVs present to vulnerable road users (VRU). Vehicles must then obtain a safety permit before entering and operating in most of Greater London.

An HGVs DVS star rating is 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.

Since the introduction of DVS in 2019, fatal collisions involving HGV’s and VRUs, where vision was a contributing factor has halved, and is now down incredibly from 12 to 6.

To further improve the safety of ALL road users, HGVs over 12T will need to have a minimum of three-star rating or fit the new PSS to operate in Greater London, from 28 October 2024.


The new PSS will come into force from 28th October 2024, and will apply to all vehicles that have a two-star rating or lower.

0, 1 & 2-star permits granted before 24 June 2024 are valid until midnight on 27 October 2024, by when these permit holders will need to have applied for a new safety permit to demonstrate that their vehicle meets the new PSS requirements to operate in London.

We will begin to accept applications under the new requirements from 24 June 2024 for vehicles that will need a permit with a PSS condition.

These permits will be valid until midnight on 28 October 2030. Existing permits (with a Safe System condition) for these vehicles will remain valid until their stated expiry date, at midnight on 27 October 2024.


Equipment fitted to your vehicle as part of meeting the PSS must comply with the specification set out here.

Operators must ensure that their equipment for indirect vision, including Blind Spot & Moving Off Information Systems (MOIS), is fully operational. Both sensor systems must meet the performance requirements in the accompanying PSS technical specifications, available online at

Camera Monitoring Systems (CMS)

To completely eliminate the remaining vehicle Blind Spot at the nearside, a Camera Monitoring System must be fitted, regardless of whether mirrors are fitted.

Incab monitors must be positioned close to a window edge or existing mirror location (without obscuring the view through the window) to minimise the time the driver needs to take their eyes off the road to see the monitor.

A Mirror Replacement Camera System may also be used as an alternative to fitting Class V and VI mirrors. Monitors only intended to show blind spots related to low speed manoeuvring, such as mirror replacement cameras, may switch off at speeds above 20mph. An additional camera monitoring system does not need to be fitted where one already exists in the vehicle, such as to replace mirrors, and the same safety benefits are achieved.

Moving Off Information Systems (MOIS)

Vehicles must have a system that activates a proximity information signal to the driver, detecting pedestrians or cyclists entering the critical blind spot area in front of the vehicle when the subject vehicle is stationary with the brakes applied.

This signal must be escalated to a collision warning if the driver begins to prepare the vehicle to move off from a resting position.

Front sensor systems must be ‘active’ and able to react to the presence of Vulnerable Road Users (VRU). They must not provide false alarms.

The system must provide a visual signal to show that it has detected a VRU in the detection area, as specified in the technical specifications. If the vehicle then moves off with the VRU detected, then a collision becomes imminent, and an audible alarm signal should sound.


Blind Spot Information Systems must be fitted to the vehicle to ensure full coverage down the nearside of the vehicle.

Sensors must not activate in response to roadside furniture or stationary vehicles where a collision is imminent. For articulated vehicles, sensors must be suitably positioned on the tractor unit to provide sufficient coverage of the nearside of the combination but without being activated by the trailer itself.

Sensors must enable detection in the defined zone, and this will extend rearward to areas adjacent to a semi-trailer. This can be achieved in the way that works best for the technology supplier and the vehicle operator.

Audible Warnings

Vehicles must be fitted with Audible Warning equipment to make nearby pedestrians, cyclists and other road users aware that the vehicle intends to carry out a turning manoeuvre.

Operators should consider fitting an Audible Warning System that combines spoken warnings and white noise. It is recommended that Audible Warning Devices require minimal driver intervention.

The device should have a manual on/off switch for use between the hours of 23:30 and 07:00.

For left-hand drive vehicles, the Audible Vehicle Manoeuvring Warning must be fitted to warn people walking and cycling when a vehicle is turning right.

Warning Signage

Warning Signage must be displayed on the rear of the Rigid Vehicle & any trailer unit in use, not the front tractor unit.

This must be designed to warn people walking and cycling of the hazards posed when near the vehicle.

The signage must not be offensive or give instructional advice to people walking and cycling. The text point size must be legible to a cyclist or pedestrian at a reasonable distance from the vehicle.

Signage used should be of at least A3 size.

NEW AI Intelligent Pedestrian Detection System

Our new AI Intelligent Pedestrian Detection System eliminates blind spots and cleverly detects Vulnerable Road Users (VRU)by providing driver’s with audible & visual warnings of pedestrians or cyclists on the road.


This gives the driver clear distances by measurement and colour codes (redamber & green) which are displayed on the cab monitor. Allowing the driver to gain more reaction time and to make a decision based on the colour coding, thus providing the driver with additional awareness and confidence in congested areas.





The AI Intelligent Pedestrian Detection Camera can be used as a single camera or with a multi camera system, allowing the camera to be used on the side of the vehicle. Ideal for use on Coaches, HGV’s and Plant vehicles.


The PS Ai Detection system can be fully integrated with our Parksafe On Demand Website platform, this allows you to have the ability to remotely view live footage, download footage remotely and track your vehicles location.

Please complete the form below with your registration and VIN number for your trucks over 12T and we will contact the manufacturer on your behalf*

Once we have your DVS star rating, if any further action is required, we can advise you with how to comply, including helping to fit any devices required.

From October 2024, all vehicles’ rates 0, 1 and 2 stars will be required to comply with the DVS Progressive Safe System (PSS). Final specifications for the DVS PSS is expected to be announced in summer 2023.
