These vehicles rode on unpaved and often dusty country roads. The only problem of traffic was an occasional pedestrian or a frightened horse or cow frenzied by the roar of this new creature. Today more than 82,000,000 registrations, representing 50 of the worlds automobiles, are recorded in this country. In 1963 these vehicles traveled 798 billion miles over newly constructed modern highways, expressways, freeways, quickways, and thru ways, as well as improved rural and urban roads and streets.

An example of this safety factor can be found by the exacting specifications for cross sections, grades, roadside control, medians, and other design features. For many years, the responsi bility for controlling traffic fell naturally into the domain of the police.
