Abstract

The purpose of this study is to ascertain what relationship, if any, exists between the several types of speed laws used in the United States and the traffic death rate per 100 million vehicle miles of travel during the 20-year period, 1935 to 1954. Any association found between speed laws and traffic death rates during this time should provide evidence from which a reasonably substantial inference may be drawn that will help to decide which statute type, or variation, that by its operation has proved most effective in reducing traffic fatalities. The null hypothesis that no relation between speed law type and traffic fatalities exists was tested.
