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.
