asked the Minister of Transport what proportion of the 331,906 licences issued for goods road motor vehicles current at the end of May are in respect of steam-propelled vehicles of the lorry and tractor type, respectively; and whether any other country permits the passage through the streets of cities of steam-driven lorries?
I am unable to state how many licences for goods vehicles current at the end of May were issued in respect of steamdriven vehicles but the census of mechanically-propelled road vehicles taken during the quarter ended September, 1929, showed that there were then 8,520 goods vehicles driven by steam. Tractors are separately classified and are not included in the figure quoted by the hon. and gallant Member. As regards the last part of the question, I have no information.
Will the hon. Gentleman make inquiries as to whether any other countries permit these heavy steam vehicles to go through the streets emitting sparks?
With regard to sparks, regulations can be made, and are under consideration, under the Road Traffic Act, 1930.
