To ask the Secretary of State for Transport, what impact assessment his Department carried out on legislative changes to the operating weight of MCBP vehicles.

There have been no legislative changes to the weight limits applicable to Mobile Concrete Batching Plant (MCBP) vehicles. The applicable legal requirements remain the same as those that apply to all heavy goods vehicles, including barrel concrete mixers. The Department does not in general conduct impact assessments on the application of existing legal requirements.

In April 2018 the Department put in place a temporary administrative arrangement to enable much of the current fleet of vehicles to be legally operated for up to the next 10 years above the standard weight limits. This is intended to provide relevant operators with time to come into compliance with those currently-applicable limits.
