Turning Radius - Illustrated

The illustration below demonstrates a comparison between two wheel or single end automotive steer, and four wheel automotive steer.

The trailers shown in the two diagrams are of the same size and wheelbase. Note the drastic reduction in turning radius provided by the four wheel automotive steering.

Four wheel automotive steer units virtually turn around on themselves.

As two wheel steer units drive around in a circle, their outside front corner juts out away from center.
