Abstract: A system for cellular communication disablement comprising: a cellular blocking device, where the cell blocking device transmits a blocking signal to block cellular communication in a localized area; leads extending from the blocking device, where the leads engage electronic indicators of a vehicle; and active signals over the leads indicating the vehicle's transmission position, wherein the cell blocking device becomes active upon receipt of active transmission signals. The active transmission signals may indicate placement of the vehicle's transmission in either park, drive, reverse or neutral. Any active signals indicating placement of the vehicle's transmission into drive or reverse causes the cell blocking device to become active.
