Having little better to do I've copied the Introduction from the 1979 edition of Roadcraft.
Quote:- "This booklet, which succeeds former versions of Roadcraft, has been prepared by police officers and embodies the knowledge and experience gained through years of driving under all conditions.
Accidents, with rare exceptions, do not occur at any given times and places, but rather in widely scattered areas and at all times of the day and night. Comparatively few of these incidents can be directly attributed to any particular road feature or vehicle defect, but it is found that in nine cases out of ten the cause of the accident can be traced to the failure of the 'human element' of the person or persons concerned.
The aim of the following chapters is to raise the reader's standard of driving to the highest possible degree of all-round efficiency. A vehicle can be a lethal weapon and, like a gun, it should be handled with care; the advice which follows is not intended to reduce the pleasure to be gained from driving, in fact the opposite is true, the more confidence and knowledge at a driver's disposal, the greater is his capacity for enjoying and taking pride in his driving. Furthermore, if the reader follows this advice he may one day save somebody's life ÷ perhaps his own."
