According to the National Academies of Science, when the law took effect there was a decrease in fatalities of about 4000 lives after the law took effect. Later, the National Academies wrote that that is, “a strong link between vehicle speed and crash severity [which] supports the need for setting maximum limits on high-speed roads,” but that, “the available data don’t provide an adequate basis for precisely quantifying the effects that changes in speed limits have on driving speeds, safety, and travel time on different kinds of roads.” They also note that on rural interstates, the free flowing traffic speed should be the major determinant of the speed limit because, “Drivers typically can anticipate appropriate driving speeds.” This is due, in part, to the strong access control in these areas but also is an acknowledgement of the difficulty of enforcing speed laws in these areas.
