TRIALS OF THE PORTABLE ROAD SIGN PRODUCED BY SAMUEL JACKSON LIMITED

The initial design of the compact sign originated from a member of the staff employed in the Staffordshire Police Vehicle workshops. It was considered that the basic stability and compactness of the design warranted further study and field trials. The designer's objective was to produce a sign of physical dimensions that permitted a full highway kit to be stowed in the trunk of a highway patrol car. The standardization of the kit for all traffic control vehicles was a longer term aim. The stand when stowed into the vehicle occupies a volume of 3200 cubic centimeters maximum, the maximum diameter being less than 12 cm. /PRB/
