A turn that remains the same throughout, getting neither wider nor smaller is called:

• A. Cycle
• B. Danger zone
• C. Cover
• D. Constant radius

Answer: (D)

A turn that stays the same size throughout has a fixed curvature, described as a constant radius turn. When the radius of the turn remains unchanged, the path is a circular arc, so the vehicle maintains the same distance from the center of the circle as you progress. This happens by maintaining a steady steering input that produces equal angular change per distance traveled, keeping the turn from widening or tightening. The other terms don’t describe this geometric idea: cycle refers to repetition, danger zone is a hazard area, and cover isn’t related to turning geometry.
