A steering mechanism for a vehicle having steered front and rear wheels, comprises steering linkages for connection to both sets of wheels. The steering linkage to the rear set of wheels includes a variable length lever and a link mechanism to vary the length of the lever in response to the amount of steering movement imparted to the steering connection to the front wheels. The variable length lever mechanism is such that the amount of steering movement transmitted to the rear wheels for a given amount of steering movement imparted to the front wheels is greater when the front wheels approach full lock than when the front wheels are moving from the straight ahead position.
