Depending on the source, driver error is cited as the cause of 45 to 75 percent of roadway crashes and as a contributing factor in the majority of crashes (Hankey, et al, 1999). However, which driver errors lead to a crash, and the degree to which these errors contribute to the crash, often cannot be specified. Instead, driver error is used as a general catchall category that is invoked when environmental and mechanical causes are no longer considered. The objectives of the "Identification and Evaluation of Driver Errors" project included: (1) Development of driver error taxonomies; (2) Determination of the causes of the identified errors; (3) Collection of data to support the use of these taxonomies in the study of incidents and accidents; and (4) Development of recommendations for improvements in traffic control devices, roadway delineations, and accident reporting forms based on the study findings. This executive summary highlights the work that was conducted and the major project results. This is a summary of Report FHWA-RD-02-003
