Massachusetts DOT to spend $6.4 million to add truck Weigh-in-Motion tech at fifteen locations statewide
Massachusetts transportation officials are moving forward with a plan to expand truck weight screening across the state.
The Massachusetts Department of Transportation will spend $6.4 million to add Weigh-in-Motion (WIM) technology at 15 locations statewide.
WIM systems measure a truck’s weight as it travels over sensors embedded in or near the roadway, allowing agencies to screen vehicle weights without requiring every truck to stop at a scale. In practice, that can help flag potentially overweight vehicles for closer inspection while allowing compliant trucks to keep moving.
For drivers, the expansion matters because weight enforcement and screening can affect trip flow, routing, and time spent near inspection areas. Adding more WIM locations can also increase the number of places where weight screening occurs, depending on how the sites are used.
The project reflects a broader push by transportation agencies to use technology to support weight compliance and roadway protection, since overweight vehicles can accelerate pavement and bridge wear.
