Direct Vision Standard / Progressive Safe System 2024

Starting in October 2024, the Progressive Safe System regulations (or Direct Vision Standard 2024) from Transport for London will affect Heavy Goods Vehicles (HGVs) weighing 12 tonnes and above when entering the Greater London Area. Newer vehicles provided by manufacturers with a 3-star rating or higher will not need any extra hardware. However, vehicles with a rating of 2 stars or below will need to make the following additions to ensure compliance:

  • MOIS (Moving Off Information System)
  • CMS – (Camera Monitoring System)
  • BSIS (Blind Side Information System)
  • Audible alerts to the driver – 1 for VRU near, 1 for imminent collision
  • Driver Alert for system faults (sensor malfunction / video loss)
  • External audible left-hand turn warning

Verify your vehicle’s current safety star rating

Vehicles that formerly attained a 1-star rating under the Direct Vision Standard 2021 regulations must install the enhancements mentioned above and successfully apply for and obtain certification for PSS. You can verify your vehicle’s current safety star rating at

Applications for updated licenses begin on 24th June 2024 via the TFL website.

The New System Requirements Explained:


CMS – Camera Monitoring

A camera aid for drivers, displayed on a monitor inside the cab, eradicates any remaining blind spots in the vicinity.


BSIS – Blind Spot Information

A sensor/camera that ensures comprehensive coverage down the entire nearside of vehicles to detect vulnerable road users. It must not identify roadside furniture or stationary vehicles (capable of recognising VRU or moving vehicles).


MOIS – Moving Off Information

A sensor to be fitted to the front of a vehicle to prevent collisions in the frontal blind spot zone where a vehicle moves off from rest (i.e., directly in front of the cab).

The driver must also be provided with a 2-stage audible warning – one for detection within the range of the vehicle and a second for an imminent collision.
