Our team is dedicated to aiding you in navigating these new requirements and ensuring your full compliance. GET IN TOUCH

The Progressive Safe System (PSS) DVS 2024 star rating

When do I need to have the DVS 2024 Progressive Safe System (PSS) Fitted?

Starting in October 2024, if your Heavy Goods Vehicles (HGVs) weigh over 12T and have a safety rating of 3 stars or lower. If you operate within Greater London, you will be required to implement a DVS Progressive Safe System to apply for a Safety Permit, allowing legal travel within Greater London. Transport for London (TfL) recently concluded a public consultation on the Direct Vision Standard (DVS) for 2024 and the proposed specifications for the Progressive Safe System. Permits granted after October 2024 will be valid for 10 years.

This is the first step to establish what equipment you will require. You can contact your vehicle manufacturer, or simply send us a fleet list and we’ll complete this work for you free of charge.

Detailed Requirements For The Progressive Safe System (PSS) in 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 Direct Vision Standard and HGV Safety Permit

Both sensor systems must meet the performance requirements in the accompanying PSS technical specifications, available online at

To completely eliminate the remaining vehicle blind spot at the nearside, a camera monitoring system must be fitted, regardless of whether mirrors are fitted. In-cab monitors must be positioned close to a window edge or existing mirror location (without obscuring the view through the window) to minimize 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 maneuvering, 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.

It’s important to note that the installation of this camera monitoring system, along with the mandatory installation of the BSIS system, is an optional component and is not currently required to conform to the new PSS legislation. While it offers a valuable solution for eliminating all nearside blind spots, it is not mandatory for compliance.


Vehicles are mandated to be equipped with a front sensor system designed to activate a proximity information signal for the driver. This system’s primary function is to detect pedestrians or cyclists entering the critical blind spot area in front of the vehicle, specifically when the vehicle is stationary with the brakes engaged.

The importance of this signal is underscored by its escalation to a collision warning if the driver initiates preparations to move the vehicle from a resting position.

It’s crucial that front sensor systems are classified as ‘active,’ ensuring their capability to promptly respond to the presence of Vulnerable Road Users (VRU) without generating false alarms.

Moreover, the system should include a visual signal mechanism to indicate the detection of a VRU within the specified detection area, adhering to the technical specifications. In situations where the vehicle begins to move with a detected VRU, signalling an imminent collision, an audible alarm signal must be activated.


Blind spot information systems are required to be installed in the vehicle to ensure comprehensive coverage along the nearside of the vehicle. It is essential that these sensors do not activate in response to stationary vehicles or roadside furniture unless a collision is imminent.

For articulated vehicles, sensors must be strategically positioned on the tractor unit to offer sufficient coverage of the nearside of the combination without being triggered by the trailer itself. These sensors should enable detection within the defined zone, including areas adjacent to a semi-trailer. The specific implementation can be tailored to what works best for the technology supplier and the vehicle operator.


Vehicles are mandated to be equipped with audible warning equipment designed to alert nearby pedestrians, cyclists, and other road users of the vehicle’s intention to perform a turning manoeuvre. The volume of this audible warning, measured at a distance of one meter from the sounder, should fall within the range of 65 to 88 decibels/dB(A).

Operators are encouraged to consider the installation of an audible warning system that combines spoken warnings and white noise. Ideally, such audible warning devices should require minimal driver intervention and include a manual on/off switch for use during the hours of 23:30 and 07:00.

For left-hand drive vehicles, it is imperative to fit an audible vehicle manoeuvring warning to alert pedestrians and cyclists when the vehicle is making a right turn.


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.

Unveiling The Hidden Consequences Of Engine Idling

White Bar

Efficient fleet management is crucial for businesses in the United Kingdom, with a focus on optimising operational costs and sustainability. Among the often overlooked expenses lies the significant impact of engine idling. Though idling may seem inconsequential, it accumulates substantial costs over time, negatively affecting both the environment and a company’s financial performance. In this article, we delve into the true costs of engine idling in UK fleet management, supported by relevant statistics and data from reputable sources.

Fuel Consumption and Financial Implications

Engine idling leads to unnecessary fuel consumption, resulting in increased costs for fleet managers. In the UK, an idling heavy-duty vehicle can consume approximately 2 litres of fuel per hour. For fleets with multiple vehicles idling for extended periods each day, the cumulative expenses become significant. According to research conducted by the Energy Saving Trust, the annual fuel cost per idling truck in the UK can range from £400 to £2,000, depending on the vehicle type and idling duration.

Maintenance and Repair Costs

Excessive engine idling also contributes to higher maintenance and repair expenses. When a vehicle idles for prolonged periods, the engine operates at lower temperatures, leading to incomplete combustion and the buildup of carbon deposits on engine components. These deposits can decrease fuel efficiency, impair engine performance, and potentially require costly repairs. The Energy Saving Trust estimates that excessive idling can result in a 10% to 15% increase in engine maintenance costs.

Environmental Impact

Engine idling significantly impacts the environment, contributing to air pollution and greenhouse gas emissions. Idling vehicles emit pollutants, including nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM), which have detrimental effects on air quality and public health. Furthermore, idling vehicles release carbon dioxide (CO2), a major greenhouse gas contributing to climate change. UK statistics indicate that heavy-duty truck idling accounts for approximately 4.3 million tonnes of CO2 emissions annually.

Productivity Loss

Engine idling not only impacts financial aspects but also reduces operational productivity. When vehicles idle instead of being on the road, valuable working hours are wasted. A study by the Transport Research Laboratory found that idling accounted for an average of 12% of total engine run time for commercial vehicles in the UK. By reducing idling time, fleet managers can improve overall productivity, optimise vehicle utilisation, and enhance operational efficiency.


The true costs of engine idling in UK fleet management extend beyond mere fuel consumption without movement. From financial implications and increased maintenance costs to environmental consequences and health concerns, the impact of idling is substantial and wide-ranging. Fleet managers must adopt strategies to minimise engine idling, such as implementing idle-reduction technologies, conducting driver training programmes, and establishing clear policies and guidelines.

By addressing and mitigating the hidden costs of engine idling, fleet managers in the UK can enhance operational efficiency, reduce fuel consumption, lower maintenance expenses, protect the environment, and create a healthier work environment for drivers and surrounding communities. Recognising and acting upon the true costs of engine idling in fleet management will lead to a more sustainable and profitable future for businesses in the United Kingdom

ULEZ Expansion in August 2023

ULEZ 2023 expansion

ULEZ Expansion in August 2023

White Bar

Navigating the Path to Cleaner and Greener Cities

In a concerted effort to combat air pollution and create a healthier urban environment, London is expanding it’s Ultra Low Emission Zones (ULEZ) in August of this year. This expansion signifies a significant step forward in the pursuit of cleaner air and reduced carbon emissions. As businesses brace themselves for the regulatory changes, it becomes crucial to understand the implications of the ULEZ expansion and how it will impact various sectors. In this article, we explore the upcoming ULEZ expansion and its implications for businesses and individuals alike.

The ULEZ Expansion

The ULEZ was initially introduced as a measure to reduce pollution caused by high-emission vehicles in designated zones. Under the expanded ULEZ, stricter emission standards will apply to a larger number of vehicles, encompassing a broader area within the city limits. This means that more vehicles will need to meet low emission requirements to enter these zones without incurring charges or penalties. The expansion aims to accelerate the transition to greener transportation and encourage the adoption of electric and hybrid vehicles.

This map shows the new ULEZ boundary and the area it will cover. Current inner London ULEZ and the new London-wide ULEZ from 29 August 2023.

Implications for Businesses:

The ULEZ expansion will have a profound impact on businesses, particularly those relying on vehicle fleets for their operations. Non-compliant vehicles that fail to meet the emission standards will face hefty charges or fines, which can significantly impact a company’s finances. Moreover, non-compliance may result in operational disruptions, delays, and even reputational damage. It is, therefore, essential for businesses to be proactive and prepared for the forthcoming changes to minimize these risks.

Your options

Londoners receiving certain low-income or disability benefits can apply to the Mayor of London’s £110 million scrappage scheme. Eligible applicants could receive a payment to scrap their vehicle, or choose a lower payment plus one or two TfL Annual Bus & Tram passes worth more than the payment alone.

London-based sole traders, micro-businesses (10 or fewer employees) and registered charities will also be able to apply to scrap or retrofit a van or minibus.

The scheme eligibility is expanding so that even more Londoners and London-based businesses and charities can benefit (from the end of July 2023). Visit the scrappage scheme pages for more information.

To help make the switch to cleaner forms of transport, there are also exclusive ULEZ support offers for successful scrappage scheme applicants, as well as offers for all Londoners to take advantage of, whether eligible for a scrappage payment or not.

To help disabled Londoners and community transport providers prepare for the expansion, the existing ULEZ grace periods (temporary exemptions) have been extended, and new grace periods have been introduced.

The £10 annual fee to register a vehicle for Auto Pay has been removed. Auto Pay lets drivers who register their vehicles avoid the risk of forgetting to pay the daily ULEZ charge and incurring a penalty charge.

The value of ULEZ and Congestion Charge penalty charges incurred have increased from £160 to £180 (reduced by 50% if paid within 14 days).

Proposed Updates to the Direct Vision Standard

White Bar

Enhancing Road Safety in London with the DVS Update

Transport for London (TfL) has conceived a series of compelling plans with the proposed updates. Their intention is to establish a Progressive Safe System (PSS) that builds upon the existing 2019 Safe System. What does this signify for you, esteemed fleet operators? Commencing October 2024, HGVs entering and operating within Greater London will be required to elevate their safety measures by attaining a minimum DVS rating of three stars. This mandates that you employ the latest safety technology and equipment available. Vehicles possessing a two-star rating or below shall be compelled to adopt the PSS and provide verifiable evidence of compliance in order to acquire the necessary permit. It is time for us to embrace this paradigm shift in the pursuit of safety.

Highlights of the Proposed Updates

  • Recognition of the potential of camera systems in improving vehicle safety and eliminating blind spots.
  • Inclusion of sensor systems for trailers.
  • Activation of sensor
    systems within a range of 2m along the vehicle’s entire length, while avoiding interference from street furniture or parked vehicles.
  • Mandatory compliance with the DVS scheme (changing from “should” to “must”).
  • Requirement of Progressive Safe Systems for vehicles not meeting Safety Permit Scheme requirements.
  • Permission for camera systems to replace class four, five, and six mirrors, ensuring comprehensive coverage of blind spots.

Penalty Charges for Non-Compliance

At present, the penalty charge associated with non-compliance of the DVS scheme in Greater London stands at £550 per day, with a reduced amount of £275 if settled within a 14-day period. Nevertheless, it is anticipated that these charges will undergo an escalation in accordance with TfL’s continuous endeavours to augment safety prerequisites.

To maintain compliance and prevent the risk of penalties, it is advisable for fleet operators to partner with seasoned experts like Fleet Witness. Our team possesses the expertise to offer valuable insights on compliance matters and provide access to cutting-edge safety solutions. By staying connected with us, fleet operators can stay well-informed about evolving requirements and ensure their vehicles adhere to the requisite standards.
