Invalid Tricycles Mr. Edwin Wainwright asked the Secretary of State for Social Services in which test or tests by the Motor Industry Research Association an invalid tricycle was blown over or otherwise overturned. Mr. Carter-Jones asked the Secretary of State for Social Services if she will make a statement on the circumstances in which an invalid tricycle overturned during MIRA wind tests. Mr. Alfred Morris No invalid tricycle overturned in the course of any of the MIRA tests. I understand that one was overturned, while being reversed, by a member of the association's staff who was not familiar with tiller steered vehicles. This was not during a test and consequently is not referred to in any of the MIRA reports.
