title: A study of commercial vehicle safety alliance's out-of-service criteria.
abstract: This paper summarizes a two-phase project that reviewed the Commercial Vehicle Safety Alliance's out-of-service criteria for vehicles. The first phase examined relevant background information and conducted a questionnaire survey of CVSA inspectors and industry representatives. The second phase of the project involved extensive collection and evaluation of accident data. The results of both phases show a high level of support, in terms of contribution to vehicle accidents, for four of the vehicle criteria (regarding brakes, load securement, tires, and wheels and rims). There was some support for coupling devices, fuel systems, lighting devices, steering and suspension. The support for the remaining vehicle criteria (exhaust systems, frames, van and open top trailer bodies, and windshield wipers) was little to none. Further research continuing the study of accident data is recommended to confirm these findings. However, the data must be collected in a consistent and detailed manner if accurate information on the relationship of accidents and vehicle criteria is to be established.
