HC Deb 25 July 1985 vol 83 c654W
Mr. Sheerman

asked the Secretary of State for Transport what information he has as to the proportion of heavy goods vehicles and public service vehicles, respectively, which come on to the United Kingdom market fitted with high penetration resistance laminated windscreens.

Mrs. Chalker

We do not keep this information, but believe most HGVs and PSVs sold here have toughened glass windscreens.
