Abstract: Methods and devices for controlling the use of an automotive horn as a function of the speed, motion, vibration or acceleration of the automotive vehicle, are disclosed. The invention contemplates methods and devices for disabling the automotive horn for a certain period of time, abating the volume or noise level of the horn, or modifying the tone or sound of the horn to a tone or sound considered less offensive. In certain embodiments, the method of control includes electronic methods for controlling the horn by connection to the speedometer, accelerometer or braking system of the vehicle. Alternatively, motion sensors, vibration sensors, or acceleration sensors may be used to control the horn. The reduction in volume or modification of sound of the horn may be accompanied by flashing lights or other warning signals as a substitute for the horn.
