A jackknife-prevention system for a tractor-trailer rig wherein the present invention is operable to engage the front brakes of the tractor-trailer tractor so as to oppose and reverse a jackknife movement upon detection thereof. The present invention includes a lateral-acceleration sensor that is mounted in the cab of a tractor trailer and transmits power from a source to a left-side circuit or right-side circuit if the tractor is skidding leftward or rightward, respectively. A steering direction sensor is configured to transmit power from said left-side circuit to both of two stopcock assemblies when steering is leftward or from said right-side circuit to both of two stopcock assemblies when steering is rightward, the stopcock assemblies responding to power input by decompressing both front-wheel brake chambers. This action, allowing the front wheels to roll when steered in the direction of a sideward skid, helps align the tractor with its trajectory.
