HC Deb 02 February 1966 vol 723 cc228-9W
96. Sir M. Redmayne

asked the Minister of Transport what is the meaning of the expression, "average casualty rate", used in her advertisements in the public Press; and what evidence supports the contention that this rate is three times higher at speeds in excess of 70 miles per hour than at speeds between 65 and 70 miles per hour.

Mr. John Morris

The term "average casualty rate" is defined as the number of persons injured per hundred million vehicle-miles of travel. Evidence that this rate is about three times higher at speeds in excess of 70 miles per hour than at speeds between 65 and 70 miles per hour is contained in a report published by the United States of America's Bureau of Public Roads in July, 1964.

I am arranging for a copy of this report to be placed in the library as soon as one is available in this country.
