The objective of this study was to survey a nationwide sample of school bus operators in order to identify and document mechanical conditions which, in the opinion of bus fleet personnel, had an impact on the safe operation of the buses, and which did not appear to be the result of inadequate/inappropriate maintenance procedures, abusive operation, or normal wear. The results of the survey consist of: (1) A list of the 368 conditions documented during the survey. Each condition is identified as a chassis or body condition, and is listed by manufacturer and bus subsystem. (2) A detailed description of 56 safety-related conditions which were judged to be significant in terms of one, or both, of the following criteria: pervasiveness (i.e., a number of operators reported the condition); operator-reported criticality (i.e., fleet personnel indicated that the condition could likely result in serious safety consequences). (3) The following data summaries: Safety-related mechanical conditions as a function of chassis and body manufacturer, safety-related mechanical conditions as a function of operating variables, and data quality as a function of operator characteristics.
