Direct Vision Standard (DVS).

An overview of the Direct Vision Standard

The Direct Vision Standard (DVS) which was first implemented in London in 2022, was launched to enhance the safety of pedestrians, cyclists, and other road users by promoting improvements to the direct vision available to drivers, thereby reducing blind spots and mitigating the risk of accidents involving vulnerable road users. Research undertaken by Transport for London (TfL) demonstrates the need for change and emphasises the need for having the right vehicle for the job.

 

DVS affects all goods vehicles over 12 tonnes if they drive into Greater London and a permit is required to comply with legislation. If an affected vehicle doesn't meet the minimum visibility criteria of the required Direct Vision Standard rating, vehicle operators need to fit extra safety devices to comply.

 

Enforced by TfL, the DVS is graded on a ‘star rating’ scale, which indicates how much visibility a driver has from their cab. The vehicle's manufacturer will issue a star rating for each vehicle, from 0-5, based on how the vehicle left the production line. Importantly, this rating does not take into account any aftermarket safety equipment that has been fitted.

​

What's changing?

From October 2024, heavy goods vehicles that do not meet the minimum requirement of 3 stars, will need to comply with the Progressive Safe System (PSS), which may require the installation of additional visibility and safety measures to provide 'indirect vision'. These Progressive safe systems must consist of MOIS (Moving Off Information Systems) and BSIS (Blind Spot Information Systems). Proof of installation must be supplied to TfL when you apply for your DVS permit, including photographic evidence and a functionality statement. Complying with the DVS Safe System will never alter the vehicle’s star rating, provided by the manufacturer, but it will permit vehicles to be driven into Greater London. HGVs driving in London without this permit will incur a penalty charge notice (PCN) of up to £550 per entry into London.

What are MOIS and BSIS?

MOIS (Moving Off Information System) – a detection system installed to the front of the vehicle 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.

BSIS (Blind Spot Information System) – a detection system installed to the nearside of the vehicle to ensure full coverage down the nearside of the vehicle. They must not activate in relation to roadside furniture or stationary vehicles. This aims to prevent left turn collisions. For articulated vehicles, sufficient coverage is required of the combination but without being activated by the trailer itself.

Let us help.

If you are unsure what your DVS star rating is or whether you comply, we can carry out a free lookup service and then offer our recommendations.

Our DVS Solutions.

We offer two key solutions which meet the DVS Progressive Safe System requirements. We will work with you to assess your vehicle needs and recommend the installation of either of the below systems to ensure compliance with the standard.

Our Radar based DVS solution is a blind spot detection system which alerts the driver to risks at key areas around the vehicle. A front and nearside 77 GHz Millimetre wave radar would be installed to detect objects and alert the driver to the presence of vulnerable road users by means of an audible and visual notification.

 

The system will be muted if the footbrake and/or park brake is applied when the vehicle is stationary. It will also sound a “Caution Vehicle Turning Left” alarm when the indicator is selected at speeds under 20mph.

 

An additional Blind Spot Camera and Monitor can be purchased with this system.

Radar Progressive Safe System includes:

  • 1 x Contel PSS BSIS 77GHz Radar 180 deg Nearside Mounted Radar.

  • 1 x Contel PSS MOIS 77GHz Radar 140 deg Front Mounted Radar.

  • 1 x CT-LTVA Left Turn Voice alarm “Caution Vehicle Turning Left”

  • 1 x Contel PSS Internal Visual and audible display.

  • 1 x Timer cut out relay for nighttime audible isolator.

  • 1 x DVS Signal Box with Tacho speed control output.

  • 1 x Audio Alarm Module.

  • 1 x Blind Spot Take Care Sticker.

  • Installation Consumables.

Our Video based DVS solution includes our Activ-Cam. The Contel Activ-Cam system is a blind spot detection system which alerts the driver to the presence of at risk vulnerable road users (VRUs) in key areas around the vehicle.

 

The Contel Activ-Cam detection zone can be programmed at the point of installation to suit the particular vehicle type and to provide compliance with specific legislation such as R151 and R159. Upon detection of VRU's in the designated detection areas, an audible and visual notification is provided, along with the corresponding camera being displayed on the monitor.

 

If the vehicle in question is fitted with a Contel Defend DVR, the alarm output from the Activ-Cam system can be programmed into the DVR, to provide invaluable information to assist audit processes.
