This is a discussion of a paper entitled "Usage Patterns and Misuse Rates of Automatic Seat Belts by System Type", by Donald W. Reinfurt, Cheryl L. St. Cyr, and William W. Hunter of the Highway Safety Research Center (HSRC). The paper reported the results of an HSRC data collection effort that assembled 4,151 observations of restraint use by drivers in North Carolina (the North Carolina study). The data presented generally agree well with the 1988 Department of Transportation (DOT) survey of belt usage rates in 19 cities (the 19-city survey, published in 1989). The paper presented data in broad categories of vehicle manufacturer, model, and occupant age, gender, and race. Other categories that may correlate with belt use or misuse, such as vehicle cost and country of manufacture, were not identified as separate categories. The study showed higher shoulder belt misuse rates than previously reported and, in contrast with other studies, a rate of manual belt use that was higher for the "under 25" age group than for either the "25-54" or the "55 and over" age categories. The authors suggest education of drivers to increase correct use of automatic restraints.
