All HGVs over twelve tonnes will need to have a Progressive Safe System installed before 28 October 2024 to operate in Greater London. 

The system includes:
Moving Off Information System (MOIS)
All vehicles must have a front sensor system that detects pedestrians or cyclists entering the blind spot area in front of the vehicle. Detection systems must not be activated by street furniture, or parked vehicles, must recognise vulnerable road users, and must activate to a range of 2m along the front of the vehicle. The requirements of error notifications and when to issue an information signal versus a warning signal when at rest and manoeuvring are specifically defined.

Blind Spot Information System (BSIS) 
The systems should only provide the information signal to the driver in response to the presence of a VRU and not a car or roadside furniture (unless a collision was imminent). The detection range must be 2m in height, 2.2m to the side, and 9m to the back. The system must be active at 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. 

Also required; Camera monitor system, audio warnings and warning signage.
Vehicles already approved to UNECE Regulation 151 and 159 are considered to have BSIS and MOIS requirements. For this reason, Motormax has chosen these specific regulated products to guarantee compliance for fleet operators.
