Abstract: A blocking system and a method for virtual blocking of SMS/MMS/EMS protocols based on vehicular and handset conditions are disclosed. One aspect of the invention is to virtually block the non-voice related messaging on a handset by disabling the display and keyboard. In one embodiment, a blocking module is installed on the handset and when conditions are met, the blocking module will disable the display and keyboard of the handset. Several parameters are monitored for determining whether the driver is engaged in driving the vehicle or is parked. Furthermore, the method and the blocking system are adapted to disable virtual blocking in times of emergency.
