Abstract The Crash Investigation Sampling System (CISS) provides a comprehensive national traffic crash database. Data collection is accomplished at 24 geographical sites, called Primary Sampling Units (PSUs). These data are weighted to represent all police reported motor vehicle crashes occurring in the USA during the year involving passenger cars, light trucks and light vans that were towed. The Crash Investigation Sampling System (CISS) is the replacement of the National Automotive Sampling System Crashworthiness Data System (NASS/CDS). CISS provides comprehensive national traffic crash information. This manual and the CISS 2017 Coding and Editing Manual are part of the primary documentations supporting the 2017 CISS data files. This document provides a detailed description of data element definitions and their attributes. 17. Key Words 18.
