Illegal Weigh Station Bypassing

Abstract

This study was conducted to determine the extent of illegal weigh station bypassing in Kentucky, including the resulting safety and financial implications. Historical data (2017 to 2021) collected by Kentucky State Police–Commercial Vehicle Enforcement, observation data, and a state survey distributed to law enforcement officials across North America were used in tandem to provide evidence that illegal weigh station bypassing is indeed a problem that justifies swift, comprehensive action. Between 2017 and 2021, there were 2,616 charges for illegal weigh station bypassing in Kentucky. Drivers charged with illegal weigh station bypassing were also charged for an average of two additional violations. Site visits to permanent weigh stations along I-75 revealed that illegal weigh station bypassing was a persistent problem, even among preclearance (PrePass and Drivewyze) users. A survey was sent to law enforcement officials across North America to determine whether other jurisdictions were experiencing similar levels of noncompliance, as well as identifying which methods were being used to combat it. With a survey response rate of 56%, and 49% of respondents reporting a recent uptick in illegal weigh station bypasses, a nationwide problem was confirmed. Despite 70% of jurisdictions reporting enforcement efforts to curb illegal weigh station bypassing, it is clear that increased enforcement levels alone will not be sufficient. With safety and financial implications mounting across North America from illegal weigh station bypassing, novel approaches are warranted.
