DVS PSS Kit

A DVS Progressive Safe System (PSS) kit is the equipment combination required to bring a zero-star or low-star HGV into compliance with Transport for London's Direct Vision Standard. Understanding what a compliant kit includes — and how to verify that what you're fitting actually meets the standard — is essential for fleet operators procuring PSS equipment.

What a Compliant PSS Kit Includes

A compliant PSS kit must include camera monitoring that covers the nearside blind spot and rear of the vehicle, with a display visible to the driver. It must also include a sensor-based system that detects pedestrians and cyclists in the immediate vicinity of the vehicle and provides an audible and visual warning to the driver.

The specific technical requirements for both the camera system and the proximity warning system are defined by TfL. Not all camera and sensor combinations meet these requirements, and operators should verify compliance for their specific vehicle configuration using TfL's DVS checker.

Approved vs. Non-Approved Equipment

TfL maintains a list of approved safety systems for DVS PSS compliance. Equipment that appears similar to approved systems may not actually meet the standard. Operators should purchase equipment from suppliers who can provide explicit documentation of TfL approval for the specific configuration being fitted.

Installation Quality Matters

A compliant kit installed incorrectly may not function as intended. Camera angles, sensor positioning, and system calibration all affect performance. Exeros provides professional installation with commissioning checks to ensure the fitted system performs as specified.

Staying Compliant

DVS requirements have been updated and will continue to evolve. Operators should build a relationship with their compliance supplier that includes proactive notification when requirements change, rather than relying on their own monitoring of TfL guidance.
