25 Investigates asked MassDOT how it identifies and stops toll cheats. Our request for an on-camera interview was declined, but in an email, the agency said, “MassDOT looks for repetitive instances of the same vehicle at various toll gantries which allows for different views of the plate and/or vehicle. MassDOT tries to knit together pictures and/or look for specific details that can be used to identify violators such as a logo on the side of a truck. Massachusetts State Police are always aware of vehicles on the roads and look for instances in which license plates cannot be read.”
