Navigating the Changes to TfL’s Direct Vision Standard: What You Need to Know

On Monday 4th September, Transport for London (TfL) released their updated guidance on changes to the Direct Vision Standard (DVS).

The current DVS Scheme for vehicles over 12 tonnes, is changing. From October 2024 the minimum star rating requirement is increasing from one to three stars. Operators that fall short of the required star rating will need to apply for a Progressive Safe System (PSS). This replaces the current Safe Permit and requires a new range of blind spot and predictive collision warning technologies. Some technologies fitted to meet the current DVS requirements will not be applicable from October 2024.

Here at Brigade, we have now reviewed the new Progressive Safe System (PSS) technical documents from TfL and we are confident that we can fully service your DVS requirements.

PSS requires technologies that can predict collisions and warn the driver with a range of audible and visual warnings depending on the severity of the danger.

A simplified Version of Requirements:

  • Predictive side sensor technology to warn the driver of a collision
  • A front sensor system that provides alerts to the driver when a vulnerable road user is in the detection path, both when preparing to move off and when moving off.
  • A nearside camera and monitor
  • An audible alarm to warn other road users that the driver is about to move
  • An A3 size DVS sticker.
  • Products must not interfere with safety critical aspects of the vehicle and must therefore have E Mark Certification

The new specification also requires the Original Equipment Manufacturer to test the products with a specific test procedure. We will be testing our DVS solutions based on this new information, so that you can rest assured that our products comply to the highest standard.
