Abstract
The principal objectives have been to ascertain how speed enforcement is being accomplished today and what changes might be appropriate considering the highway conditions that now prevail. As in a previous study, a survey by questionnaire was conducted. Most of the questions asked in 1947 were still valid in 1968. The purpose in asking them again was as before, to discover the degree of variation in regulation and practice; and second, to discover the prevailing attitudes of enforcement officials and the resultant effects on enforcement policies.
