A jackknife correction system is provided for an articulated trailer truck vehicle. The system comprises an on dashboard activation switch A in a dc system of the tractor unit. An electrical power connection B connects an additional flat engine E installed on the trailer. A drive shaft F from the engine E is coupled to two or more trailer axles. The engine E is fed by an additional small fuel tank C via a fuel line D. When the system is activated through switch A, the engine E is immediately ignited. It begins to accelerate up to reach its preset rotational speed settings. An installed centrifugal clutch between engine E and shaft F is then set into motion, engaging engine E to shaft F which is coupled to the axles, providing a drive force which is transferred from shaft F to the axles, causing back traction in a reverse direction. Correction can occur whilst the driver uses engine braking and steers in a straight line. The invention tends to return the vehicle to its initial axes. The system can then be reset.
