When riding, you should:

Turning your head and eyes to look where you are going is crucial for safe riding. This technique allows a motorcyclist to maintain a proper posture on the bike, ensuring better balance and control while being aware of their surroundings. By moving your head and eyes, you can significantly expand your field of view, which is vital for spotting obstacles and other vehicles.

Using only mirrors does not provide a complete picture of the environment; blind spots can remain unseen, potentially leading to dangerous situations. Leaning your body can help in some scenarios, such as turning, but it doesn't effectively enhance visibility around obstacles. While checking behind you is important for overall awareness, especially before changing lanes or merging, it is not the primary action that contributes to looking where you are going as effectively as the head and eye movement does. Prioritizing head and eye movement ensures a better response to hazards and smoother navigation.
