A simple and easily-installed system for vehicles equipped with an extensible pole, mast, boom, or other structure, providing an audible alarm when the operator attempts to drive away without first completely retracting the pole, mast, boom, or other extensible structure. The system includes a sensor for sensing a first position and a second position of a vehicle's gearshift lever, and a control module. The control module receives an electrical signal from an extensible structure when the extensible structure is fully or partially deployed and communicates the electrical signal to an audible alarm if the sensor senses that the vehicle's gearshift lever has been moved from the first position to the second position.

What is claimed is: 1. An audible alarm system for vehicles having an extensible structure, the system comprising: a sensor for sensing a first position and a second position of a vehicle's gearshift lever, wherein the sensor is affixed to an exterior of the vehicle's dashboard; and a control module, the control module receiving an electrical signal from said extensible structure when the extensible structure is fully or partially deployed and, wherein the control module communicates the electrical signal to an audible alarm if the sensor senses that the vehicle's gearshift lever has been moved from the first position to the second position, and wherein the system does not inhibit the vehicle from being driven. 2. The system of claim 1, wherein at least a portion of the sensor is affixed to the vehicle's gearshift lever. 3. The system of claim 1, wherein the sensor is a microswitch. 4. The system of claim 3, wherein the microswitch is a normally closed single pole single throw microswitch. 5. The system of claim 1, wherein the sensor is an infrared LED and an infrared receptor affixed to an exterior of the vehicle's dashboard. 6. The system of claim 1, wherein the sensor is a magnetic device. 7. The system of claim 6, wherein the magnetic device comprises a magnetic sensing switch and a magnet. 8. The system of claim 1, wherein the control module comprises an enclosure, a circuit board, and a plurality of electrical connections. 9. The system of claim 1, further comprising a remotely controlled switching device. 10. The system of claim 9, wherein the switching device is an electromechanical device. 11. The system of claim 9, wherein the switching device is a semi-conductor circuit which uses the existence of a control voltage to enable a passage of electricity from the device's input terminal through it to its output terminal. 12. The system of claim 9, wherein the switching device is an optical switch device. 13. The system of claim 9, wherein the switching device is a magnetic circuit. 14. The system of claim 1, wherein the alarm is a piezo alarm siren. 15. The system of claim 1, further comprising a flashing light. 16. The system of claim 1, wherein the first position is park and the second position is any other drive position. 17. An audible alarm system for vehicles having an extensible structure, the system comprising: a sensor for sensing a first position and a second position of a vehicle's gearshift lever, wherein the sensor comprises a magnetic sensing switch affixed to a vehicle's dashboard and a magnet affixed to the vehicle's gearshift lever; and a control module, the control module receiving an electrical signal from said extensible structure when the extensible structure is fully or partially deployed and, wherein the control module communicates the electrical signal to an audible alarm if the sensor senses that the vehicle's gearshift lever has been moved from the first position to the second position and wherein the system does not inhibit the vehicle from being driven. 18. The system of claim 17, wherein the first position is park and the second position is any other drive position. 19. A method of warning an operator of a vehicle having an extensible structure when the vehicle is about to be driven with the extensible structure deployed, the method comprising the step of: sensing a first position and a second position of a vehicle's gearshift lever; receiving an electrical signal from said extensible structure when the structure is fully or partially deployed; and communicating the electrical signal to an audible alarm if the vehicle's gearshift lever has been moved from the first position to the second position and wherein moving the gearshift lever does not inhibit the vehicle from being driven. 20. The method of claim 17, wherein the first position is park and the second position is any other drive position. 21. An audible alarm system for a television microwave truck having an extensible pneumatic mast, the system comprising: a sensor for sensing a first position and a second position of the truck's gearshift lever, wherein the sensor is affixed to an exterior of the truck's dashboard; and a control module, the control module receiving an electrical signal from the extensible pneumatic mast when the extensible pneumatic mast is fully or partially deployed and, wherein the control module communicates the electrical signal to an audible alarm if the sensor senses that the truck's gearshift lever has been moved from the first position to the second position. 22. The system of claim 21, further comprising a microwave transmitter attached to the extensible pneumatic mast. 23. The system of claim 22, wherein the truck is an ENG van.
