What should a rider do before entering a curve?

Answer: C — Adjust speed and position

Adjusting speed and position before entering a curve is crucial for maintaining control and safety while riding a motorcycle. By reducing speed appropriately, the rider can better handle the turn and avoid losing traction. At the same time, positioning the motorcycle correctly in the lane—whether that's towards the inside or the outside of the curve—allows for a smoother and safer transition through the turn. This approach helps to counteract the natural centrifugal force experienced in a curve, allowing the rider to lean into the turn without risking a fall or losing control. Furthermore, adjusting speed before entering the curve provides time for the rider to assess the road conditions and any potential hazards, ensuring a more confident and safer riding experience.
