The first radio is equipped for two-way communication with one or both of a base station and at least one second radio of a second vehicle. The second switch is engageable to a floorboard of the first vehicle and can be actuated by a foot of an operator. Programming code, which is selectively positionable on a microprocessor of the first radio, enables the microprocessor to accept signals from the first and second switches. Switching of the first switch signals the microprocessor to operate the first radio in a handsfree operational mode, wherein a microphone and a transceiver of the first radio are actuated upon actuation of the second switch. ## Claims ### Claim 1 A selectively handsfree communications module comprising: a first switch configured to be operationally engaged to a control panel of a first radio mounted in a first vehicle, wherein the first radio is equipped for selective two-way communication with one or both of a base station and at least one second radio positioned in a second vehicle; a second switch configured to be engaged to a floorboard of the first vehicle, such that the second switch is positioned for being actuated by a foot of an operator of the first vehicle, the second switch being configured to be operationally engaged to the first radio and the first switch; and programming code selectively positionable on a microprocessor of the first radio enabling the microprocessor for accepting signals from the first switch and the second switch, wherein the first switch is configured for switching for signaling the microprocessor for operating the first radio in a handsfree operational mode by operation of the second switch, wherein a microphone and a transceiver of the first radio are actuated upon actuation of the second switch. ### Claim 2 (depends on 1) The selectively handsfree communications module of claim 1, wherein the first switch comprises a toggle switch engaged to the control panel. ### Claim 3 (depends on 1) The selectively handsfree communications module of claim 1, wherein the second switch comprises a plunger switch. ### Claim 4 (depends on 3) The selectively handsfree communications module of claim 3, wherein the plunger switch is engaged to the floorboard between a brake pedal and a sidewall of the first vehicle, wherein the plunger switch is configured for selective depression by a left foot of the operator. ### Claim 5 (depends on 3) The selectively handsfree communications module of claim 3, wherein the programming code enables the microprocessor for connecting the first radio to the base station upon a single depression of the plunger switch and for connecting the first radio to the base station and the at least one second radio upon a second depression of the plunger switch. ### Claim 6 A selectively handsfree communications system comprising: a first vehicle; a first radio mounted in the first vehicle, the first radio comprising a microprocessor, a transceiver, and a control panel, the transceiver and the control panel being operationally engaged to the microprocessor, wherein the first radio is configured for selective two-way communication with one or both of a base station and at least one second radio positioned in a second vehicle; a first switch operationally engaged to the control panel; a second switch engaged to a floorboard of the first vehicle, the second switch being operationally engaged to the first radio and the first switch, wherein the second switch is positioned for being actuated by a foot of an operator of the first vehicle; and programming code selectively positionable on a microprocessor of the first radio enabling the microprocessor for accepting signals from the first switch and the second switch, wherein the first switch is configured for switching for signaling the microprocessor for operating the first radio in a handsfree operational mode by operation of the second switch, wherein a microphone and a transceiver of the first radio are actuated upon actuation of the second switch. ### Claim 7 (depends on 6) The selectively handsfree communications system of claim 6, wherein the first switch comprises a toggle switch engaged to the control panel. ### Claim 8 (depends on 6) The selectively handsfree communications system of claim 6, wherein the second switch comprises a plunger switch. ### Claim 9 (depends on 8) The selectively handsfree communications system of claim 8, wherein the plunger switch is engaged to the floorboard between a brake pedal and a sidewall of the first vehicle, wherein the plunger switch is configured for selective depression by a left foot of the operator. ### Claim 10 (depends on 8) The selectively handsfree communications system of claim 8, wherein the programming code enables the microprocessor for connecting the first radio to the base station upon a single depression of the plunger switch and for connecting the first radio to the base station and the at least one second radio upon a second depression of the plunger switch. ### Claim 11 A selectively handsfree communications module comprising: a first switch configured to be operationally engaged to a control panel of a first radio mounted in a first vehicle, wherein the first radio is equipped for selective two-way communication with one or both of a base station and at least one second radio positioned in a second vehicle, the first switch comprising a toggle switch engaged to the control panel; a second switch configured to be engaged to a floorboard of the first vehicle, such that the second switch is positioned for being actuated by a foot of an operator of the first vehicle, the second switch being configured to be operationally engaged to the first radio and the first switch, the second switch comprising a plunger switch, the plunger switch being engaged to the floorboard between a brake pedal and a sidewall of the first vehicle, wherein the plunger switch is configured for selective depression by a left foot of the operator;
