Written question asked by Lee Dillon (Liberal Democrat) on Thursday, 16 October 2025, in the House of Commons. It was due for an answer on Monday, 20 October 2025. It was answered by Keir Mather (Labour) on Wednesday, 22 October 2025 on behalf of the Department for Transport.

Large Goods Vehicles: Carbon Emissions

Question: 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.

Answer

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.
