§ Mr. Loughton
To ask the Secretary of State for the Environment, Transport and the Regions how many HGVs have converted to road fuel gases since May 1997. 
§ Ms Glenda Jackson
The number of HGVs able to run on road fuel gases increased from 41 vehicles in the first quarter of 1997 to 96 vehicles in the third quarter of 1998, according to the latest statistics from the DVLA vehicle register. While this increase is small, the Government expect that there will be strong growth in the number of HGVs converting to road fuel gases, particularly for those vehicles predominantly operating in urban areas.
