Log truck safety study
The Forest Engineering Research Institute of Canada (FERIC), performed vehicle dynamic research into common log truck configurations during the Western Log Truck Study between 1992 and 1998.
The main conclusion of this study was that the majority of existing logging trucks failed to meet the minimum criteria for safety performance, when hauling Alberta winter weights.
During 1999 and 2000, FERIC undertook a supplementary project to determine what improvements could be made to bring the safety performances up to the minimum standard.
Based on the results of this study, recommendations for the specifications of logging trucks have been developed, as contained in the Western Log Truck Study – Improvements to Dynamic Stability report.
