1. A warning system for alerting a vehicle driver to different types of traction losses comprising:

  • a first sensing circuit for detecting a loss of adhesion by a vehicle wheel with respect to a relatively moving traction surface;

    a second sensing circuit for detecting application of a vehicle brake;

    a logic circuit for combining sensor signals from said first and second sensing circuits and for producing a first command signal indicative of the detection of both the loss of adhesion by said vehicle wheel and the application of said vehicle brake and a second command signal indicative of the detection of the loss of adhesion by said vehicle wheel but not the application of the vehicle brake;

    a first indicator responsive to the first command signal of said logic circuit for alerting the vehicle driver to wheel skidding; and

    a second indicator responsive to the second command signal of said logic circuit for alerting the vehicle driver to wheel slipping.
