<p>At the rear of a towing vehicle for attachment of a trailer, a fifth wheel (10) is mounted upon a slider carriage (12) which is slidably displaceable upon a slider frame (14) between predetermined front and rear positions, for example as defined by notches (17, 27), relative to intended direction of vehicle travel. A sensor (26) detects when the fifth wheel (10) is in its rear position and the sensor (26) is connected to the electrical management system of the towing vehicle so as to limit the operation or speed of the vehicle whenever the fifth wheel is in its rear position.</p> |
