HC Deb 20 January 1987 vol 108 c463W
Mr. Maxwell-Hyslop

asked the Secretary of State for Transport what medical evidence has now emerged to indicate a correlation between smoking while driving and an increased accident rate.

Mr. Peter Bottomley

None that I am aware of. Our advice remains that if drivers must smoke they should only do so if they can be sure that their ability to concentrate will not at any time be affected.
