Technical specifications and timelines have been published by TfL since the summer of 2023. Whilst the specifications are detailed, they are not 100% clear and in places could be viewed as contradictory. This ambiguity/lack of clarity and scope of the changes has led to suppliers offering different PSS solutions. Sadly, it has also meant a lot of ‘new arrivals’ to market offering discount solutions. It would seem wise to be wary of new operators and evaluate all solutions based on merit and likelihood of fulfilling the TfL requirements rather than purely price. Long established and accredited suppliers with long standing relationships with manufacturers will bring you the compliant solutions. ACSS have designed a system not only to fulfil the TfL requirements but to exceed and offer the highest level of protection and safety for vulnerable road users (VRU) and HGV drivers.
