PSS goes live in October 2024 and affects all HGV's over 12T GVW rated 0, 1 or 2 stars
DVS has been updated as ongoing research in London, has shown that road safety can be improved due to the increasing availability of assistive technologies.
"Operators must ensure that their equipment for indirect vision, including blind spot and moving off information systems, is fully operational. We recommend that indirect vision devices are fitted to operate with a minimal amount of driver intervention necessary, to enable a positive driving experience." TfL HGV safety permit guidance
Images below are from the HGV Safety Permit Guidance Document
A fully operational camera monitoring system(CMS) must be fitted to the nearside of the vehicle, to eliminate any remaining blind spots along the nearside regardless of whether there are mirrors fitted
- Must include an in-cab monitor positioned close to a window edge or existing mirror location without obstructing the drivers view
- Monitors must only show blind spots related to low speed manoeuvring
- CMS may switch off at speeds above 20mph
- Class V and VI mirrors may be replaced with a camera monitoring system
Class V and VI mirrors, or a camera monitoring system if used in place of the mirrors, or a combination of both, must befitted to the vehicle.
These should be fitted in compliance with UNECE Regulation 46
A blind spot information system, with active detection that gives adequate warning to the driver of the presence of a vulnerable road user, must be fitted to the nearside of the vehicle in accordance with the technical specifications for the PSS.
- Must ensure full coverage down the nearside of the vehicle
- Must not activate in response to roadside furniture or stationary vehicles unless a collision is imminent
- Sensors must be suitable positioned on the tractor unit to provide sufficient coverage of the nearside but not activated by the trailer itself
- Sensors must enable detection in the defined zone and extend to the rear areas adjacent to a semi-trailer. This can be achieved by using a suitable technology supplier to assist the vehicle operator. Fastview360 is our partnered supplier.
A moving off information system (MOIS) must befitted to the front of the vehicle to warn the driver of the presence of a vulnerable road user, in accordance with the technical specifications for the PSS.
- When the vehicle is stationary and the brakes are applied, the MOIS must alert the driver to the presence of pedestrians or cyclists entering the critical blind spot area in front of the vehicle. When the vehicle starts to move, the signal must be escalated.
- Must be active and able to react to vulnerable road users in the detection zone§
- Must not provide false alarms
- Must provide a visual signal to the driver to warn of a vulnerable road users in the detection zone
- When a vulnerable road user is detected and a vehicle moves – an audible alarm signal should sound
An audible vehicle manoeuvring warning must befitted to provide an adequate audible warning to vulnerable road users when a vehicle is turning left.
- Device should have a manual on/off switch for between the hours of 23:30 and 07:00§
- Volume of the warning sound should be between 65 and 88 decibels
- Audible warnings should be a combination of spoken words and alerts to minimise drive intervention
- Lefthand drive vehicles – system to alert when a vehicle is turning right
External pictorial stickers and markings must be displayed on vehicles to provide adequate visual warning to vulnerable road users of the hazards present around the vehicle§
- Must not be instructional
- Must be displayed on the rear of all vehicles; rear of rigid vehicle, rear of trailer and rear of tractor units when a trailer is not present
- Must be visible for a vulnerable road user from a reasonable distance
- Signage should be of at least A3 size
Side under-run protection must be fitted to both sides of the vehicle, except where this is demonstrably impractical. This equipment must be fitted in compliance with UNECE Regulation 73 on lateral protection devices.
- Must be fitted to both sides of the vehicle (unless demonstrably impractical on one side)
- Should consider improved sideguard design e.g. flat panel sideguard
Over 250,000 vehicles now have DVS permits.
Any vehicles rated under 3 stars need to update to PSS.
Thousands more vehicles do not have DVS permits and will be under 3 stars. These will require permits to access London without being fined.
Relevant to all HGV's (over 12T GVW) rated 0, 1 and 2 stars. This comes into enforcement from 28th October 2024
The enforcement zone covers central London and some outer London. To view the enforcement zone please click below
