The Interim Report presents preliminary results based on the first year of the fleet monitoring program to evaluate the safety impact of FMVSS 121. Mileage, accidents, and brake system maintenance are being collected on a national sample of vehicles. The fleets and vehicles were selected from manufacturers' sales lists for the production period January 1974 through January 1976 using probability-based sampling techniques. A complete description of the sample design is included. Preliminary results indicate that the adjusted accident rate is slightly lower (19%) for the post-standard vehicles. However, brake system maintenance on the post-standard vehicles occurs more frequently (35%). These results are not statistically significant.
