Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 17 October 2025 to Question 81178, what estimate his Department has made of the proportion of volumetric concrete mixers which operate over the incoming 32 tonne limit.

The Department does not hold specific data on the proportion of volumetric concrete mixers that operate above the forthcoming 32-tonne weight limit.

In the concrete delivery sector, the Department estimates there are in the region of 1,000 VCMs in operation. Existing vehicles can continue to operate beyond the end of the temporary arrangement provided they are loaded to the lower weight limits (for example, up to 32 tonnes for 4 or more axle rigid vehicles).
