HC Deb 20 July 1987 vol 120 c38W
Sir Anthony Grant

asked the Secretary of State for Transport if he has any proposals to restrict signs affixed to vehicle windows.

Mr. Peter Bottomley

Our regulations already require windows to be kept in a condition such that the driver's vision is not obscured and for the driver to have a full view of the road and traffic ahead. There are no plans to change these requirements.
