Which action is recommended to check for blind spots while riding a motorcycle?

Turning your head to the left and right is the recommended action to check for blind spots while riding a motorcycle because it provides the most accurate assessment of your surroundings. Motorcycle mirrors have limitations in their field of vision and may not show everything happening around you, particularly in your blind spots, which are the areas not visible in your mirrors. By turning your head, you expand your vision and ensure that you are aware of other vehicles or obstacles that may not be reflected in your mirrors. This motion helps increase safety by allowing you to make better-informed decisions before changing lanes or merging.

Option A, zooming out on the mirrors, is not feasible as motorcycle mirrors do not have a zoom function. Checking only the left mirror, as mentioned in option C, limits your visibility to just one side and could allow other vehicles to go unnoticed on your right side. Looking straight ahead, as suggested in option D, does not take into account the need to monitor the areas in your blind spots, which could lead to dangerous situations on the road.
