ABSTRACT:
This disclosure pertains to a signaling apparatus installed within a movable large vehicle, such as a truck. Two sensing heads are utilized by mounting one of each on the frontmost opposed sides of the vehicle. Each sensor is manually selectively energized so as to detect the distance separating a vehicle being passed from the equipped vehicle on the side of the energized sensor. The sensors may utilize sound, radio or light waves to operate a conventional range detecting apparatus. A comparetor circuit compares the range of the vehicle being scrutinized with the range manually predetermined by setting a minimum range control element. A warning light continues to indicate the proximity of the scrutinized vehicle until such time that the vehicle remains within the pre-set distance manually selected by the operator. A timer may be used to shut off the sensing activity of the sensor in the event of intentional herding of adjacent vehicles oftentimes encountered in heavy traffic.
