For stabilizing a tractor and/or a trailer of a tractor-trailer unit against jackknifing, the tractor and/or trailer carries a gyroscopic mass which spins about a horizontal first axis. The tractor and/or trailer is operably uncoupled from the mass during a non-jackknifing of the tractor and/or trailer to permit free relative swiveling between the spinning mass and the tractor and/or trailer about a vertical second axis. Such relative movement can be prevented during a jackknifing state wherein a precessing of the spinning mass occurs about a horizontal third axis oriented perpendicular to the first axis and produces a torque that is transmitted to the jackknifing component for opposing the jackknifing motion thereof.
