An Act relative to the tracking of certain electronic devices

This bill restricts how Massachusetts toll collection systems can use data from electronic devices like transponders and GPS. It prohibits using this information for any purpose other than charging tolls and forbids sharing it with law enforcement without a valid warrant. The law also makes illegally obtained data inadmissible in court and allows individuals to sue for damages if their privacy is violated. While it generally requires a warrant for access, it permits emergency exceptions where there is an immediate threat of death or serious injury, provided officials document the emergency within 48 hours.
