This Terminology is a compendium of motor vehicle safety and environmental
engineering words and phrases, and their definitions. They have been extracted
verbatim from SAE Standards, Recommended Practices, and Information
Reports, published in the 1994 SAE Handbook. An Appendix contains a listing,
in J-number sequence, of the reports from which the terms were extracted. The
terms are reported as they were developed and reported by SAE technical
committees concerned with passenger cars, trucks, and certain recreational
vehicles, and their related components, systems, operation, and maintenance.
