Question to the Department for Transport:

To ask Her Majesty's Government what estimate, if any, they have made of the number of volumetric concrete mixer vehicles produced in the UK in each of the past five years.

No specific estimate has been made of the number of this vehicle type produced in the UK on an annual basis in each of the past five years. A total of 1106 volumetric concrete mixers are currently in circulation in Great Britain operating under Vehicle Special Orders permitting them to operate at higher than usual weights. The Department’s estimate is that these vehicles represent the vast majority of the type in operation at that time and that the service life of the vehicles average effectively about ten to twelve years.
