Vehicle Defect Analysis
The high level analysis of vehicles in general for vehicle defects showed a high correlation of the defect type and the vehicle type, which is expected since certain defects apply only to trucks. Thus, the study was divided into two separate analyses, one for large trucks and the other for passenger cars. To a large extent large trucks are already inspected by the FMCSA and the ALEA Motor Carriers Unit. The passenger car analysis showed that tires account for over 70% of the fatal crashes caused by vehicle defects in cars, and that speed is a major co-factor.
