Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the environmental impact of reducing the maximum operational weight of volumetric concrete mobile plants to 32 tonnes from 2028.

Following regulatory changes in 2017, a temporary regime was put in place to allow a limited number of volumetric concrete mixers (VCMs) to temporarily operate at higher than standard weights until 2028 at the latest. An impact assessment was undertaken at the time of the regulatory changes in 2017 .
