Comprehensive Truck Size & Weight Limits Study Technical Reports

As part of the MAP-21 Comprehensive Truck Size & Weight Limits Study, FHWA has developed a series of Technical Reports that contain the technical analyses required by the Study. These Technical Reports cover the study areas of Bridge, Compliance, Modal Shift, Pavement and Safety. The Technical Reports compare the impacts of vehicles currently operating above Federal truck size and weight limits to those operating at or below these limits as well as assess various impacts of alternative truck configurations if they were allowed to operate above current federal size and weight regulations. Below are these Technical Reports.
