A Case Study of Motor Vehicles Violating Special Weight Permits in the State of Washington


The objective of this paper was to address the problem of accelerated highway and bridge deterioration from overloaded trucks by developing a profile of trucks which exceed overweight permit authorization. The profile of trucks in violation of overweight permits include location, seasonal variation, commodity group, origin/destination, scale type and permit type. The profile was developed from a statewide telephone survey of permit violations between November 1, 1991 and October 31, 1992 and provide policy makers, transportation planners and law enforcement officials greater understanding of the nature of load-related damage created by overload permit violations.
