Ensuring fleet safety and compliance is a critical responsibility every transport manager must undertake. A key aspect of this role is selecting a Progressive Safe System (PSS) that meets the requirements of the Direct Vision Standard (DVS). This guide outlines four areas of considerations for sourcing DVS-compliant vehicle safety systems, including CCTV kits and cameras, ensuring your fleet meets the standards set by Transport for London (TfL).
What is DVS and Why Comply with TfL Requirements?
The Direct Vision Standard (DVS) is an initiative by Transport for London (TfL) aimed at reducing road fatalities by improving drivers' visibility of vulnerable road users (VRU). DVS ratings are determined by how much a driver can perceive directly through windows without cameras or mirrors. For vehicles that do not meet the required DVS rating, Progressive Safe System (PSS) and DVS Cameras play a crucial role in enhancing visibility and compliance.

1. Sourcing Progressive Safe Systems from a FORS Associate
Why Choose a FORS Associate for DVS?
The Fleet Operator Recognition Scheme (FORS) is a voluntary accreditation scheme that drives best practices for commercial vehicle operators. It provides a framework for fleet operators to achieve exemplary levels of safety, efficiency, and environmental protection. TfL recommends sourcing DVS safety equipment, such as the Progressive Safe System (PSS), from a FORS associate, this can ensure quality, reliability, and full DVS compliance.
2. Ensuring Full Compliance
DVS Coverage Requirements
When selecting a DVS Progressive Safe system (PSS), it is crucial to ensure comprehensive coverage. The system must cover the blind spot areas set out by TfL. Including side, rear, and front views. A complaint system can enhance a driver's indirect vision, allowing them to be more aware of the vehicle's surroundings, and significantly reduce the risk of accidents involving vulnerable road users.
The DVS Progressive Safe System (PSS) enhances driver safety by integrating advanced detection technologies, including the Blind Spot Information System (BSIS) and the Moving Off Information System (MOIS). These systems, essential components of the PSS, are designed to identify and distinguish between stationary and moving objects around the vehicle, alerting drivers only to moving hazards. By eliminating blind spots on the nearside and front of the vehicle, the PSS ensures both comprehensive coverage and compliance with TfL's Direct Vision Standard (DVS) requirements, significantly improving road safety.
3. Importance of Testing to TfL’s Detailed Specifications
Rigorous Testing Standards
Durite’s Progressive Safe System (PSS) has been rigorously tested to ensure full compliance with Transport for London’s (TfL) Direct Vision Standard (DVS) requirements, including the technical specifications for the Blind Spot Information System (BSIS) and Moving Off Information System (MOIS).
The Durite PSS has been Independently tested by Loughborough University, a TfL-appointed testing body. Our system passed all required tests, including the static tests for nearside visibility and advanced testing to eliminate false positives from non-hazardous objects. Durite PSS has met all upcoming DVS Phase 2 requirements, ensuring it delivers both enhanced safety and full compliance. For a detailed walkthrough of our testing process, check out our video guide.
4. Additional Considerations When Sourcing a PSS
Warranty, Customer Support and After-sales Service
The warranty is an important factor when investing in PSS and other vehicle safety equipment. A solid warranty not only reflects the manufacturer’s confidence in their product, but also provides you with protection against potential defects or failures. Durite Progressive Safe System is type approved and comes with a 2-year warranty as standard to ensure peace of mind.
Alongside our fully compliant kit, Durite provides exceptional technical support to ensure seamless implementation and reliable maintenance—an essential factor when sourcing safety systems you can trust. The quality of after-sales service can significantly impact the overall experience and effectiveness of your DVS CCTV system. It’s advisable to evaluate the customer support offered by suppliers, considering factors such as response times, availability of technical support, and the ease of accessing spare parts or replacements.
