Direct Vision Standard Guidance

Transport for London (TFL) has now released its HGV safety permit guidance to support phase one of the Direct Vision Standard (DVS). The new legislation, applicable for vehicles over 12 tonnes, starts in October 2020 but operators can start applying for permits in October 2019.

We now have a selection of Direct Vision Standard HGV Safety System now available to order online.

DVS Timeline

October 2019

DVS Permit and Safe System applications open

October 2020

DVS legislation live in Greater London for vehicles over 12 tonnes banning vehicles rated 0 stars.


DVS star requirements increased to 3 stars

Do I Require a Permit?

All vehicles over 12 tonnes and operating in Greater London will need a permit.

If your vehicle meets the minimum requirements for the Direct Vision Standard of one star, you will automatically be granted a permit. However, there are few vehicles that will meet this.  If your vehicle does not meet the requisites, you can still be eligible for a permit by applying for the Safe System. The Safe System is a specification, similar to that of FORS silver and CLOCS, that requires devices for indirect vision (cameras, sensors and audible alarms) to be fitted to the vehicle to improve driver visibility.

How Do I Find Out What My DVS Star Rating Is?

Vehicle operators need to contact their vehicle manufacturer to find out what their DVS star rating is. There is currently no published list available. Operators will need the VIN number of the HGV to hand.

What Indirect Vision Devices Are Required for the Safe System?

Devices that comply with the London lorry scheme include:

  • A camera monitor system fitted to the nearside
  • A proximity sensor system with audible driver alert to warn the driver to the presence of a vulnerable road user on the nearside, such as a cyclist
  • An audible vehicle manoeuvring warning “Caution: this vehicle is turning left”

Brigade Electronics has a range of products to help operators meet the requirements of various specifications including the safe system for the Direct Vision Standard. Brigade’s team of experts work closely with road safety associations and charities to provide the best and most up to date advice. Interpreting various specifications and understanding the terminology can be a minefield for operators. For example, references to ‘shall’, ‘should’ and ‘may’ in the Direct Vision standard depict whether a requirement is mandatory, recommended or permitted and transport managers can be left confused.

The Direct Vision Standard in Detail

Camera Monitoring Systems

Camera monitoring systems should eliminate the nearside blind spot. Brigade has a range of camera types suitable for the Direct Vision Standard including; high definition, wide angle, shutter and flush mount with mirror or normal view. A range of cables, adapters and ancillaries are also available. For the ultimate blind spot coverage Brigade’s Backeye®360 eliminates all blind spots around a vehicle by providing four camera images that appear as one seamless image on the monitor in the cab.

Monitors in the cab are required to be positioned close to a window edge or existing mirror location without obscuring the window. Monitors should only display camera views for low speed manoeuvring such as turning left and reversing, and may turn off at speeds above 20mph.

Sensor System

Brigade’s ultrasonic proximity sensors can be fitted to vehicles to meet Direct Standard compliance. According to the London lorry specification, the sensors should be fitted to rigid vehicles and articulated tractor units and should ensure coverage six metres down the nearside or one metre from the rear of the vehicle. Brigade’s proximity sensors are activated by the left turn indicator and it is recommended that the system turns off at speeds above 20mph so as not to cause driver overload or distraction.

Sensor System that Alerts the Driver

Brigade’s sensor system alerts the driver to the presence of a vulnerable road user via a graduated visual and audible distance warning display which draws the driver’s attention to their blind spots. For the ultimate coverage Brigade offers an Ultrasonic On-Screen Display Module which integrates proximity sensors and camera monitor systems. The ultrasonic detection warnings are overlaid onto a camera image on the in-cab monitor and provide a three-stage audible and visual warning.

Audible Vehicle Manoeuvring Warning to Alert the Vulnerable Road User

To comply with the London lorry scheme, it is mandatory that vehicles over twelve tonnes are fitted with an audible vehicle manoeuvring warning to alert the vulnerable road user that the vehicle is turning left. Brigade’s Backchat provides a real speech warning to the pedestrian and cyclist “this vehicle is turning left.”

Camera Systems Should Comply with GDPR

All of Brigade’s camera monitors can be connected to digital recording systems. To check whether your cameras or digital recording systems are compliant with GDPR regulations, Brigade has created a handy guide and checklist.
