Which spike line orientation indicates steering?

Explanation:
The key idea is how a spike line on the chart mirrors the actual steering action. Steering changes the vehicle’s heading, not just moving straight or sliding sideways, so the spike line that reflects a steering input is the one described as steered. The other orientations would correspond to motions or signals that don’t show a deliberate change in direction. So the steered orientation is the best indicator of steering because it directly matches the action of turning the heading.
