HC Deb 19 July 1973 vol 860 c186W
Mr. Proudfoot

asked the Minister of Posts and Telecommunications what change there has been in the number of accidents to Post Office telephone vehicles since they were painted yellow.

Sir J. Eden

Accident rates are influenced by many factors and it is not possible to measure the effect of any particular one. However, the Post Office tells me that there were 10 per cent. fewer accidents per million miles in the 12 months ended December 1972 compared with the same period immediately before the change in colour was introduced.
