§ Mr. Chris Davies
To ask the Secretary of State for Transport on what occasions in the past five years his Department has issued advice intended to reduce the danger of road traffic accidents attributable to lost wheels to(a) manufacturers and (b) operators of heavy commercial vehicles. 
§ Mr. Norris
At the Institute of Road Transport Engineers conference in May 1991, my Department launched a pamphlet dealing with the subject of wheel loss and giving advice to operators.
We are in constant contact with manufacturers and operator's trade associations on this problem through my Department's representation on the British Standards Institution committee for wheels and tyres and other forums.
