§ Mr. Kershaw
asked the Minister of Transport how many accidents involving motor cyclists occurred between 1st May, 1964 and the latest convenient date; and whether he will express in figures the comparison between the degree of safety enjoyed by those motor cyclists who used crash helmets and those who did not, during this period.
§ Mr. Marples
National road casualty statistics are published for each month, and I will send my hon. Friend the figures for May as soon as they are available. These monthly figures do not show the effect of wearing safety helmets but our studies confirm that the risk of head injuries is reduced.
