In October 2024, the Direct Vision Standard (DVS), a permit to drive HGVs into Greater London, will undergo significant changes that all operators must be aware of. One of the key changes is the minimum star rating requirement, which will increase from one to three stars. This adjustment signifies a higher emphasis on safety, particularly for vehicles that fall short of the star rating. To obtain a permit, these vehicles will now need to be equipped with extra safety equipment.
The Transition from Safe Permit to Progressive Safe System (PSS)
Previously, the permit for additional safety equipment for HGVs was referred to as a “safe permit.” However, starting in October 2024, it will be known as the “Progressive Safe System” (PSS). This transition is part of the broader effort to enhance safety standards. The PSS introduces the latest advancements in technology, which means that some operators may need to replace their existing equipment with new, more advanced technology.

Advanced Technology in Predicting Collisions for DVS Compliance
The PSS requires a significant shift in technology. Unlike the previous safe permit, which required obstacle detection systems on the nearside, the Progressive Safe System demands technology that can predict collisions based on the trajectories of the vehicle and the vulnerable road user (VRU). This prediction is crucial in determining if a collision is imminent. Furthermore, the system includes a specified alarm strategy designed to alert the driver to the severity of the situation.
Understanding UNECE Regulation 151 and 159 vs. DVS Requirements
It’s important to clarify the distinctions between UNECE Regulation 151 and 159 and the DVS requirements. These regulations have different detection areas. For instance, in terms of side detection, Regulation 151 allows for a specific gap, whereas DVS mandates detection right up to the side of the vehicle. The same applies to front detection, where Regulation 159 allows a gap, but DVS requires detection right up to the nose of the vehicle. The General Safety Regulations (GSR) reference whole vehicle homologation rather than individual components. Therefore, a product meeting Regulations 151 and 159 may not necessarily meet DVS requirements at the aftermarket stage.
DVS Equipment Certification and Compliance
The PSS outlines specific test procedures, placing the responsibility on DVS equipment manufacturers to confirm that their products meet the requirements through a ‘sensor functionality statement.’ Manufacturers must also provide details on how their products integrate with other systems without compromising safety-critical aspects or vehicle performance. Products with an E-mark certification will meet these requirements.
Evidence needed to comply with the PSS
Operators will need to upload documentation with photographic evidence of compliance. This documentation will be crucial for monitoring and enforcement. Any non-compliance issues identified later can be readily traced back to the manufacturer used. It is essential for fitters to confirm that the sensors fitted to the vehicle are active and installed in compliance with the technical PSS specification. This approach will promote both product and installation quality.
Sensor Functionality Statement
The PSS sets out specific test procedures and it is the responsibility of the DVS equipment manufacturer to confirm that products meet the requirements via a ‘sensor functionality statement.’ This should include details of how the products link with other systems and confirmation that they do not adversely affect any safety critical aspects or performance of the vehicle. If a product has an E-mark it will meet these requirements.
The document will need to be uploaded by the operator. If there are any non-compliance issues identified at a later date, it will be easily identified from the manufacturer used. Fitters will also need to confirm that the sensors fitted to the vehicle are active and fitted in compliance with the technical PSS specification.

Where in London is the DVS Enforceable?
Our DVS map below outlines the area of London where the DVS regulation is currently in force and where permits are compulsory. Don’t forget this will apply to all vehicles weighing more than 12 tonnes, whether they are from the UK or traveling into London from overseas.
