Question to the Department for Transport:

To ask the Secretary of State for Transport, whether her Department plans to extend the (a) 38.4 and (b) 44 tonne limits for lower carbon construction vehicles after 2028.

The Department ran a call for evidence from October to December 2023 seeking views on three potential options on weight limits for Volumetric Concrete Mixers (VCMs). The outcome of this review was published on 18 March 2025.

VCMs will continue to be permitted on our roads, but as planned, a temporary weight limit exemption for this type of vehicle (via vehicle special orders) will end on 31 March 2028, after which VCMs must operate at the legal weight limits applicable to other heavy good vehicles. This is not a ban or change in policy.

There are no plans to extend the 38.4 or 44 tonne weight limits for Volumetric Concrete Mixers beyond 2028.
