asked the Secretary of State for Transport, further to the reply, Official Report, 17 November, c. 195, what his Department's policy is with regard to the fitting of hazard warning lights to tricars in present use.

A retrospective requirement for users to fit hazard warning lights to existing invalid tricars would be costly and difficult to implement, and the accident record is not such as to justify a step of that kind. But, as I said in answer to the hon. Member on 17 November, we shall be making this a requirement for new vehicles.—[Vol. 32, c. 195.]
