摘要： A coupling linking a tractor 10 and a trailer 11 having a fifth wheel assembly 12 having a longitudinal outwardly tapering slot defined by spaced ears 15 is provided with an anti-jackknifing apparatus A, B. Sensor C located adjacent a rear wheel 16 of the trailer generates a frequency reflective of the speed of the tractor and trailer. A radar gun, and the like or other sensor may also be used to determine ground speed. Upon receiving a frequency corresponding to a speed exceeding a predetermined speed, a speed controlled switch D engages the anti-jackknifing apparatus. Similarly, the switch D automatically disengages the apparatus upon receiving a frequency signal corresponding to a speed below the predetermined speed or, upon the occurrence of certain conditions, the activation of a turning signal by the driver. A signal light E mounted externally on the trailer indicates when the apparatus has been activated.
