asked the Minister of Transport whether he can give any information to the House in connection with experiments recently conducted on the resistance to skidding exerted by various road surfaces?

The trial sections to which I referred in my reply to the hon. Member's question on 18th June last have since been laid along the course of the Kingston by-pass in Surrey, and the nonskid qualities of the various materials are now being tested. These trials will, however, have to proceed for a long period under varying weather conditions before reliable deductions can be drawn.
