A fifth wheel trailer coupling system comprises a plurality of proximity sensors which, through a controlled area network bus system, transmits data to an engine/electronic control module which, depending upon the sensor readings, is adapted to transmit an alert to an operator or transmit signals to control units to alter operating parameters of a tractor. The plurality of sensors comprises a fifth wheel position sense adapted to detect fifth wheel positioning beneath a trailer chassis; a kingpin sensor adapted to determine kingpin positioning within a fifth wheel yoke; a jaw sensor adapted to determine jaw positioning; a fifth wheel height sensor adapted to determine fifth wheel height; and a weight sensor adapted to measure the weight of the trailer near the weight sensor.
