HC Deb 19 January 1987 vol 108 c386W
Mr. Gareth Wardell

asked the Secretary of State for Transport what regulations govern the making by London taxi drivers of U-turns on main roads.

Mr. Peter Bottomley

Unless prohibited by a traffic regulation order, this manoeuvre may be carried out anywhere provided that it is safe to do so. London-type taxis are specially constructed so as to be able to execute this kind of turn.
