A vehicle simulating frame assembly is supported on a track recording surface by pairs of non-dirigible tractor wheels spaced laterally outward of track marking devices plotting parallel spaced track lines on the surface in response to wheeled movement of the frame assembly along a path recorded as a center guide line equally spaced between the track lines. The frame assembly is steered along the path by a dirigible guide wheel aligned with said center guide line and angularly displaceable by means of a steering spindle between angular limits corresponding to the maximum steering cramp angle of the vehicle being simulated.
