The Direct Vision Standard (DVS) and HGV safety permit scheme for heavy goods vehicles (HGVs) requires operators of lorries over 12 tonnes gross vehicle weight to obtain a safety permit before entering and operating in most of Greater London. Otherwise, you may receive a Penalty Charge Notice (PCN).


The Direct Vision Standard and HGV Safety Permit Scheme are part of the Mayor of London's Vision Zero plan to eliminate all deaths and serious injuries on London's transport network by 2041.

The DVS measures how much an HGV driver can see directly through their cab windows. This is expressed as a star rating from zero (limited) to five (good) direct vision, indicating the level of risk to vulnerable road users, such as people walking and cycling.

Direct Vision Standard requirements in London are changing. To improve the safety of all road users, heavy goods vehicles over 12 tonnes will need to have a three- star rating or fit the Progressive Safe System to operate in Greater London, from 28 October 2024.

Regulation 151 & 159

Vehicles already approved to UNECE Regulation 151 and 159 are considered to have BSIS and MOIS requirements. For this reason, G-Force Communications have created these specific kits to guarantee compliance for fleet operators.

Moving Off Information Systems (MOIS)

Vehicles must have a Moving Off Information Systems (MOIS) that detects pedestrians or cyclists entering the blind spot area in front of the vehicle, when the vehicle is stationary with the brakes applied. This signal must be escalated to a collision warning if the driver begins to prepare the vehicle to move off from a resting position. Front sensor systems must be ‘active’ and able to react to the presence of Vulnerable Road Users (VRU). They must not provide false alarms.

The system must provide a visual signal to show that it has detected a VRU in the detection area, as specified in the technical specifications. If the vehicle then moves off with the VRU detected, then a collision becomes imminent, and an audible alarm signal should sound.


Blind Spot Information System (BSIS)

All vehicles must have a Blind Spot Information System (BSIS). The systems should only provide the information signal to the driver in response to the presence of a Vulnerable Road User (VRU) and not a car or a piece of roadside furniture (unless a collision with those items was imminent). The detection range must be 2m in height2.2m to the side, and 9m to the back. The system must be active at all vehicle speeds between 0 km/h and 30 km/h and able to issue information signals and warnings irrespective of the activation status of the direction indicators.


Camera Monitoring Systems (CMS)

To completely eliminate the remaining vehicle Blind Spot at the nearside, a Camera Monitoring System must be fitted, regardless of whether mirrors are fitted. Incab monitors must be positioned close to a window edge or existing mirror location (without obscuring the view through the window) to minimise the time the driver needs to take their eyes off the road to see the monitor. A Mirror Replacement Camera System may also be used as an alternative to fitting Class V and VI mirrors. Monitors only intended to show blind spots related to low speed manoeuvring, such as mirror replacement cameras, may switch off at speeds above 20mph. An additional camera monitoring system does not need to be fitted where one already exists in the vehicle, such as to replace mirrors, and the same safety benefits are achieved.

Audible Warnings

Vehicles must be fitted with Audible Warning equipment to make nearby pedestrians, cyclists and other road users aware that the vehicle intends to carry out a turning manoeuvre. Operators should consider fitting an Audible Warning System that combines spoken warnings and white noise. It is recommended that Audible Warning Devices require minimal driver intervention. The device should have a manual on/off switch for use between the hours of 23:30 and 07:00.

For left-hand drive vehicles, the Audible Vehicle Manoeuvring Warning must be fitted to warn people walking and cycling when a vehicle is turning right.


Warning Signage

Warning Signage must be displayed on the rear of the Rigid Vehicle & any trailer unit in use, not the front tractor unit.
