Abstract
A multi-axle traction vehicle is equipped with apparatus for sensing the speeds of its respective drive axles, and control apparatus is provided for producing a predetermined warning signal if the sensed speed of one and only one of the axles is less than a predetermined low threshold level. In addition, apparatus is provided for inhibiting the control apparatus unless all but one of the sensed axle speeds are greater than a predetermined higher threshold level thereby minimizing the opportunity of producing a false warning signal.
