NATIONAL ACCIDENT SAMPLING SYSTEM. NONREPORTED ACCIDENT SURVEY

The National Accident Sampling System (NASS) is the data collection program from which the National Center for Statistics and Analysis (NCSA) will estimate national totals for categories of police-reported accidents, in support of the research of the National Highway Traffic Safety Administration. Because there is currently no provision in NASS for sampling non-police reported accidents, NASS could underestimate accidents, injuries, and societal costs associated with traffic accidents. The survey described in this report provides estimates of the magnitude of the non-police reported accident problem and thereby a means for adjusting for the underestimate. Telephone interviews were conducted with a nationally-representative set of 6,541 households with follow-ups to 5,424 of these households. A total of 215 police-reported and 264 non-police reported accidents were described in the form of a detailed set of questionnaires. This report describes the results and implications of the study.
