Michigan's experience in passing a much publicized primary belt use law in the Fall of 1999 provides strong evidence of the benefits of primary enforcement laws. Statewide driver seat belt use increased from 70 percent in September 1999 to 84 percent in March 2000. In attitude surveys, officers consistently preferred primary laws and report that a secondary enforcement law is a major deterrent to issuing citations.
