preferred embodiment , a radio frequency identification signal emitter device is contained in an emergency vehicle , in contact with the emergency vehicle , in contact with the emergency vehicle operator and / or in contact with a passenger in the emergency vehicle . such a signal emitter device for transmitting data relating to a motorized vehicle regulation , emergency information and / or emergency command addresses a signal specifically to a particular motorized vehicle . in one embodiment of the present invention , a signal emitted from a signal emitter includes information relating to identification of a particular vehicle . such a signal may be broadcast and received by a signal receiver in a plurality of vehicles . in one option , each signal receiver receiving the information includes processing and memory circuitry for comparison of the broadcast information relating to identification of a particular vehicle with information specific to the vehicle in which the receiver is contained . a comparison is performed , and , where the broadcast information relating to identification of a particular vehicle matches information specific to the vehicle in which the receiver is contained , a control signal pertaining to a vehicle regulation , emergency information and / or emergency command is generated . for example , a license plate number or other identifier may be input

from a signal emitter is directed to a particular vehicle by limitation of the range of signal emission , such that only a vehicle in the immediate vicinity of the emitter will receive the signal . in further embodiments , an inventive system includes a plurality of signal emitter devices for transmitting a signal containing data relating to a motorized vehicle regulation , emergency information and / or an emergency command . in such an embodiment , the plurality of signal emitter devices may be located in contact with a plurality of emergency vehicles . inventive systems and processes are used in marine vehicles in one embodiment . one or more signal emitters may be positioned at sea , on lakes or on rivers , to assist vehicle operators in avoiding marine navigation hazards such as shoals , rocks , and high traffic areas . for instance , a signal emitter may be attached to a buoy . inventive systems and processes may also be used in conjunction with off - road terrestrial vehicles , such as snowmobiles . one or more signal emitters may be placed near hazards such as thin ice in order to protect vehicle operators . as noted above , where it is determined that the motorized vehicle is not in compliance with the regulation , a control signal is generated by the electronic device which is communicated to an effector . the effector responds to the control signal , directly or indirectly , to bring the motorized vehicle into compliance with the motorized vehicle regulation . the effector may illustratively be a component of a fuel injection system , an ignition system , a braking system , an engine airflow intake system , or a combination of these or other effectors . for example , in a direct injection spark ignited internal combustion engine having one or more combustion chambers , fuel injection is controlled by an electronic engine controller unit ( ecu ) conventional in the art . an ecu is a conventional computer including data input and output capacity , processing circuitry , memory circuitry and an executable program for controlling engine functions . the ecu receives signals from various sensors coupled to various components of the vehicle engine . fuel is delivered to the combustion chamber by a high pressure fuel system which typically includes a fuel tank , a fuel pump and a fuel rail . the amount of fuel injected into the chamber is proportional to the pulse width of a signal from the ecu . thus , an effector which is a component of a fuel injection system may include the ecu , and a control signal to the ecu may direct the fuel injection system to deliver less fuel to the combustion chamber , resulting in reduced engine torque and lower engine speed . alternatively , fuel supply to one or more cylinders may be shut off completely to reduce engine power . a speeding vehicle may be brought into compliance with the speed limit by controlling fuel injection . in a further example , an effector includes a component of an engine airflow intake system . in a typical vehicle having an internal combustion engine , activating the accelerator pedal is effective to introduce more air into the combustion chambers , increasing engine torque and thus engine speed . the accelerator pedal may be mechanically coupled to an air intake valve such that depressing the pedal opens the valve and increases engine air intake . alternatively , the accelerator pedal may be coupled to an air intake valve electronically , such as by a sensor which senses the position of the pedal and interpolates a desired increase in speed from the position . a signal to an effector which is a component of an engine airflow intake system may uncouple pedal position from air intake , such that the operator of the vehicle is no longer able to increase the speed of the vehicle . in one embodiment , a second throttle valve is included , controlled by the ecu and a control signal from the electronic device included in a system of the present invention . an effector is optionally a component of the braking system of a motorized vehicle . a signal to a component of the braking system is effective to decrease the speed of the vehicle . for example , hydraulic pressure may be increased in a brake line so as to activate braking in one or more brakes . the effect of accelerator pedal depression by the vehicle operator is optionally uncoupled from air intake in conjunction with activation of braking , so as to more effectively control speed of the vehicle . in a further option , an effector is a component of the ignition system of the vehicle . for example , a control signal may inhibit spark or retard spark timing to one or more cylinders in an internal combustion engine . thus , for example , voltage supplied to one or more spark plugs is decreased or eliminated in order to decrease combustion and thereby decrease engine torque and engine speed . in one embodiment , the effector is actuatable to turn off the engine of the motorized vehicle . the engine may be automatically restarted once the vehicle is in compliance with the regulation . an effector may further be operative to inform a driver regarding a regulation or emergency vehicle command . in one embodiment , an effector includes an audio system of the motorized vehicle and a control signal is effective to direct emission of audio information informing the driver of the approach of an emergency vehicle . a driver may also be informed of directions and commands issued by the operator and / or passengers in an emergency vehicle by emission of audio information . for example , a control signal may be effective to change a radio station to an emergency broadcast frequency for emission of information directed to the operator of the motorized vehicle . a control signal may further be operative to activate the radio if required . alternatively , a specialized audio system may be included in a motorized vehicle for responding to a control signal . such an audio system may be dedicated to function in response to a signal emitter and a control signal . a vehicle operator may be given an amount of time in which to respond to the audio information and bring the vehicle into compliance with a particular regulation and / or command . where the vehicle is not brought into compliance , a control signal is communicated to an effector to automatically bring the vehicle into compliance . in a further embodiment , an effector operative to inform a driver regarding a regulation or command is a visual display , such as a continuous or blinking light in the driver &# 39 ; s vehicle . again , the driver may be given a period of time to respond to the visual display and bring the vehicle into compliance with particular regulation and / or command . where the vehicle is not brought into compliance , a control signal is communicated to an effector to automatically bring the vehicle into compliance . while systems and processes of the present invention are described herein primarily with reference to slowing a speeding vehicle down to bring it into compliance with a speed limit , it is appreciated that at least some of the above controls may be used to increase the speed of a vehicle if desired . in a further embodiment , an effector is a component of a steering system of a motorized vehicle . in particular , off - road vehicles may be controlled by a control signal to the steering system such that the vehicle turns to avoid a hazard or restricted area . a control signal effective to turn a vehicle may be used in conjunction with a control signal effective to activate and effector to change the speed of the vehicle . a process for automatically bringing a motorized vehicle into compliance with a motorized vehicle regulation is provided by the present invention which includes providing a signal receiver in contact with a motorized vehicle and receiving a signal from a signal emitting device , such that the signal is received by the signal receiver in data communication with an electronic device disposed in the motorized vehicle . the signal contains data relating to a motorized vehicle regulation , directly or indirectly . the electronic device has data input and output capacity , processing circuitry , memory circuitry and an executable program for analysis of the data from the signal emitter device to determine whether the motorized vehicle is in compliance with the motorized vehicle regulation and , where the motorized vehicle is not in compliance with the regulation , for generating a control signal . thus , an inventive process further includes determining whether the motorized vehicle is or is not in compliance with the motorized vehicle regulation . such a determination may be made by comparison of the current state of the vehicle with the regulation . for example , where the regulation is a speed limit , the actual speed of the vehicle is compared with the speed limit . if the vehicle is not in compliance with the regulation , a control signal is generated which is effective to activate an effector and automatically bring the motorized vehicle into compliance with the motorized vehicle - regulation . fig3 illustrates a process of the present invention in the form of a flow chart . included in an inventive process 300 is receiving a signal directed specifically to a motorized vehicle from a signal emitter device via a signal receiver in contact with a motorized vehicle , shown at 310 . further included at 320 is determining that the

automatically bring the motorized vehicle into compliance with the motorized vehicle regulation , as shown at 330 . inventive systems and processes may be implemented for a variety of uses . one embodiment of an inventive system is directed to control of vehicles which are part of a fleet of commercial vehicles , such as delivery trucks or rental vehicles . in such an embodiment , a plurality
